What are the dew point comfort ranges? Why do we have dew pointss? — Preceding unsigned comment added by 72.152.218.24 ( talk) 21:11, 12 March 2012 (UTC)
What is a good empirical formula for calculating dew points based on temperature and relative humidity?
I have two questions / suggestions for extra material.
1. I understand the diagram shows the percentage of water vapour that can be carried as a component of air at a given temperature. But what is it a percentage by? Percentage weight, percentage volume, percentage of moles, something else?
2. Are the physiological reasons known why a high dew point is held to be oppressive? Notinasnaid 15:51, 11 November 2005 (UTC)
will a change in air temperature cause the dew point temperature to change as well? —Preceding unsigned comment added by 216.6.155.118 ( talk) 02:22, 4 December 2009 (UTC)
I used this formula vs. wunderground.com's ambient conditions, and the formula was incorrect. -- 130.18.64.104
This article needs to be re-named. Dew point is ambiguous. There are two phycial properties that are closely related Dew Point Pressure AND Dew Point Temperature. The article clearly is speaking of the latter.
When one says "the dew point" it is often correct to assume that the dew point temperature is being spoken of, however, this is not always the case.
In addition the dew point temperature of a gas or vapor is dependent on the absolute pressure of the gas - that is to say: dew point temperatures must always be refrenced to a pressure and dew point pressures must always be referenced to a temperature.
The article doesn't explain or ellude to this important relationship.
This figure looks like it was done in about 1 minute with very little effort, should this figure not be polished up significantly? chiefhoser 08-08-2006
how can the dew points be changed? Can dew points only be changed by temperature?
the article defines very nicely what dewpoint temperature is and how it can be calculated. What i'm missing here is some background information on what determines the dewpoint. (Relative humidity, yes, but what influences RH? You can't just say RH is determined by DP, and DP is determined by RH, you have to give information on what influences the relative humdity/DP which should be considered as one factor, since RH is just the consequence of the DP and T)
I'm confused. The article says that "If the temperature rises without changing the absolute humidity, the dew point will rise accordingly." Since the absolute humidity is "the mass of water in a particular volume of air" and the dew point temperature is "the temperature to which the parcel must be cooled, at constant barometric pressure, for water vapor to condense into water", it seems to me that for a fixed, isolated parcel of air, the dew point temperature is independent of the current temperature of this parcel.
So I do not understand why the dew point should rise? —Preceding unsigned comment added by Ph martin ( talk • contribs) 27 June 2007

Anyone know the highest dew point ever recorded? I haven't seen anything above 86F.
Answer from mtn-man... The record high dew point in the world is 93 degrees, observed near Dubai, on the Persian Gulf in the United Arab Emirates. 22:20, 31 January 2007 (UTC)
Comment on 24 October 2007 ... mtn-man answer of 93°F near Dubai, UAR is often suggested as the world record highest dewpoint temperature; however the date of 31 January 2007 is suspect because the weather records for that date at Dubai International Airport and at Sharjah International Airport indicate a maximum recorded dewpoint on that date of 16.8°C (62.2°F). In US Air Force report AFCRL-70-0563 dated 6 October 1970 Grantham and Sissenwine of the Air Force Research Laboratories reported a 33.6°C (92.5°F) record dewpoint for Sharjah in the month of July. The year of this event in vague and some evidence suggests that it was in the period 1940-1953. One problem in determining the record high dewpoint is that most world meteorological stations record temperatures every three hours in contrast to some who claim a high dewpoint record only list a single instantaneous reading often not at an official meteorological station. Many claims for record dewpoints originate at desert locations when an approaching thunderstorm thrusts a short duration burst of moisture into a location. K289g 15:14, 24 October 2007 (UTC)
I cannot find any verification for the unsubstantiated claims for record dew points:

The Houston Chronicle has a good article about the uselessness of dew point at http://www.chron.com/disp/story.mpl/headline/features/4100421.html Ewlyahoocom 18:58, 18 February 2007 (UTC)
The beginning of the article says that dew point is the temperature to which humid air must be cooled, while maintaining the same pressure, to cause its water vapor to begin to condense: i.e., the saturation temperature of the water in the air at whatever the partial pressure of water vapor is. This matches up with what I remember from thermodynamics. If the temperature is increased while maintaining the same absolute humidity (mass of water per volume of air), the partial pressure of water vapor has been increased (although water vapor close to saturation is not an ideal gas by any means, it still exhibits the same trends, so if mass and volume are held constant while temperature increases, pressure must increase). This, in turn, means that the saturation temperature must increase (the mixture of water vapor and dry air now does not need to be cooled as much to cause the water vapor to start condensing).

This article assumes that the term dew point applies only to air-water mixtures when it can apply to any mixture of two or more components. When cooling a mixture at constant pressure the dew point is the point that the first drop of liquid forms. Similarly when heating a liquid, the bubble point is the temperature that the first bubble is formed. Event Horizon 23:40, 16 September 2007 (UTC)
Here are two references:
Gatley, D., Understanding Psychrometrics, ASHRAE (2003), pages xi and 269

Quote. Some broaden the definition of psychrometrics to cover mixtues of the gas of one substance (any dry gas component or a mixture of dry gases) and the condensable vapour of a second substance. Examples include hydrogen-water, hydrogen-carbon tetrachloride, oxygen-carbon tetrachloride, air-toluene, air-bezene.
The book "Handbook of Psychrometric Charts, D.C. Shallcross, Kluwer (1997) contains over 300 charts of which 38 apply to air-water vapour and the remainder are other hydrocarbons and other chemical substances.
Since the Wikipedia "Psychrometrics" section begins with "Psychrometrics or psychrometry are terms used to describe the field of engineering concerned with the determination of physical and thermodynamic properties of gas-vapor mixtures." this should be sufficient justification to change the wording in dew point {temperature}. k289g K289g 16:15, 4 November 2007 (UTC) K289g 13:48, 5 November 2007 (UTC)

From the 'Varying pressure' para:

I thought the wikipedia entry for dew point has an inadequate definition. Especially for persons like me who see the dew point listed on a weather report and want to know exactly what it means. Only after spending a lot of time reading everything written about dew point in wikipedia and the supplied links have I finally been able to surmise that dew point is not a reading ..... but a calculated value. That should be the first point made in the definition if I have gotten that idea correct. Since it is a calculated value, and not an actual reading, doesn't that also imply it will have no effect on plants, such as those that are tender to frost? Thus if a temperature reading is 33 F and the dew point is 27, isn't it so that there should be no frost damage to plants that can tolerate temperatures down to actual freezing which is 32? The definition should cover all this, or it is worthless to someone like me. 68.43.123.159 ( talk) 11:12, 18 May 2009 (UTC) Mike Price
Specific to the original question, a dewpoint below freezing is in no way a threat to tender plants. The dewpoint is a measure of air humidity although it is expressed in degrees. For the care of plants you should look at the forecast minimum temperature, but also be aware that this is the air temperature at some distance from the ground. Freezing conditions at ground level and frost can occur when the official air temperature is several degrees above freezing. If you want to get more advanced, you can start to form your own predictions by looking at the dewpoint. When the air temperature drops close to the dewpoint, water starts to condense out and this releases a considerable amount of heat. Mist or low cloud may also form, again limiting the drop in night temperatures. When the dewpoint is very low, the air can cool much more quickly with no checks, and this is one reason that nights are cold in the desert. Watch out for very cold conditions where the dewpoint may drop rapidly at night as the small amount of air moisture quickly freezes out. —Preceding unsigned comment added by 90.206.27.152 ( talk) 15:50, 4 February 2010 (UTC)
I suspect the respective discussions are reversed. (-- Wesgin ( talk) 17:13, 4 October 2009 (UTC))
The first graph implies that the dew point can be less than the freezing point of water (close to -60C). The second implies that it can't be. Which is true? If the first is true, how can water exist in a gaseous state at sub-freezing temperatures? —Preceding unsigned comment added by 86.155.155.209 ( talk) 17:21, 7 March 2010 (UTC)
The table has strange values in the right-hand column - some ranges are non-contiguous, others overlap:
Dew Point °C | Dew Point °F | Human Perception [1] | Rel. Humidity at 32 °C (90 °F) |
---|---|---|---|
>Higher than 26 °C | >Higher than 80 °F | Severely high. Even deadly for asthma related illnesses | 65% and higher |
24 - 26 °C | 75 - 80 °F | Extremely uncomfortable, fairly oppressive | 62% <-- should be a range here |
21 - 24 °C | 70 - 74 °F | Very humid, quite uncomfortable | 52% - 60% |
18 - 21 °C | 65 - 69 °F | Somewhat uncomfortable for most people at upper edge | 44% - 52% |
16 - 18 °C | 60 - 64 °F | OK for most, but all perceive the humidity at upper edge | 37% - 46% <-- overlaps row above |
13 - 16 °C | 55 - 59 °F | Comfortable | 31% - 41% <-- overlaps row above |
10 - 12 °C | 50 - 54 °F | Very comfortable | 31% - 37% <-- two ranges start at 31% ??? |
<10 °C | <49 °F | A bit dry for some | 30% |
I wrote a C++ app (for my own purposes). I notice that my own (Fahrenheit) calculations, using the first formula (August-Roche-Magnus approximation), have different values for the humidity:
>80 °F | Severely high. Even deadly for asthma related illnesses | 72% and higher |
75 - 80 °F | Extremely uncomfortable, fairly oppressive | 61% - 71% |
70 - 74 °F | Very humid, quite uncomfortable | 52% - 60% |
65 - 69 °F | Somewhat uncomfortable for most people at upper edge | 44% - 51% |
60 - 64 °F | OK for most, but all perceive the humidity at upper edge | 37% - 43% |
55 - 59 °F | Comfortable | 31% - 36% |
50 - 54 °F | Very comfortable | 26% - 30% |
<49 °F | A bit dry for some | 25% and lower |
Can anyone defend the original values?
Unrelated to the numerical problems with the table, the table itself seems really really subjective. I'm amused that the tables suggest that a dew point of 75-80 F is extremely uncomfortable and oppressive... when I live perfectly comfortably in such an environment (dew point 27 C, RH 84 % for today) everyday. --

The grammar used in the first sentence doesn't make sense:

Query: why isn't the determination of the dew point as a factor in finding humidity explained in "old farmer's terms"? My city's weather station admits to using this as much more reliable for our area than algorithms or exponentials:
1. They literally open the window and stick out a glass of room-temp water with a thermometer in it.
2. The moment the glass begins to develop condensation, it is brought inside and the temp is noted. That is registered as the dew point.
3. The percentage of the temperature that the dew point represents is what is reported as the humidity percentage.
...and I think they screw that up often. Yesterday it was 64, the dew point was 61 and somehow they calculated the humidity at 91% which is clearly wrong. I'm no mathematician but that seems to represent closer to 97%, meaning in my fevered brain I see 61 as being around 97% of 64.
Does anyone else know of what I speak, and agree it should be in the calculating section? Also, why is this exclusively in Celsius? Fahrenheit equivalents ought to be in there. 75.21.97.145 ( talk) 22:34, 23 June 2011 (UTC)

"At a given temperature but independent of barometric pressure, the dew point is a consequence of the absolute humidity, the mass of water per unit volume of air. If both the temperature and pressure rise, however, the dew point will increase and the relative humidity will decrease accordingly. Reducing the absolute humidity without changing other variables will bring the dew point back down to its initial value. In the same way, increasing the absolute humidity after a temperature drop brings the dew point back down to its initial level. If the temperature rises in conditions of constant pressure, then the dew point will remain constant but the relative humidity will drop. For this reason, a constant relative humidity (%) with different temperatures implies that when it's hotter, a higher fraction of the air is water vapor than when it's cooler."
This entire paragraph and the following one are awful. They are the long-winded talk of a person who is explaining it to himself for practice by going through cases. But it's not even correct:
"At a given temperature but independent of barometric pressure, the dew point is a consequence of the absolute humidity..."
"If both the temperature and the pressure rise, the dew point will increase..."
The dew point of a sample of air does not depend on the temperature. It is a temperature !!! It depends on the water content of the air and the pressure.
Even the correct parts of these paragraphs are wordy and confusing. These two paragraphs should be replaced by something brief and correct. 84.227.241.146 ( talk) 07:24, 13 September 2014 (UTC)
First of all, this is an article about the dew point, so I don't think it should have a whole section dedicated to the frost point. A "See also" would suffice.
Secondly, the section is obviously wrong in saying that the frost point is always higher than the dew point. If that was true, then on an ordinarily humid summer day, with temperature, say, 25 degrees Celsius, we should see frost on our beer glasses before they are covered in dew. Since, as everyone knows that such a miracle never happens, it's obvious that the dew point must be higher than the frost point.
And finally, the external source referenced ( http://www.theweatherprediction.com/habyhints/347/) looks rather flakey to me.
May I suggest that the section be deleted? 83.251.176.228 ( talk) 06:14, 24 September 2014 (UTC)

The article states that cracked skin etc can be expected when the dew point is way below zero; however, this can happen at dew points that are as high as the 20s in many people.
Also this:
Discomfort also exists when the dew point is low (below around −30 °C (−22 °F)). The drier air can cause skin to crack and become irritated more easily. It will also dry out the respiratory paths. The U.S. Occupational Safety and Health Administration recommends indoor air be maintained at 20 to 24.5 °C (68.0 to 76.1 °F) with a 20-60% relative humidity (a dew point of −4.5 to 15.5 °C (23.9 to 59.9 °F)).[8]
recommends indoor air be maintained at 20 to 24.5 °C (68.0 to 76.1 °F) with a 20-60% relative humidity (a dew point of −4.5 to 15.5 °C (23.9 to 59.9 °F)).[8]
That is a huge recommended range. I believe what it's meant to be is an inverse sliding range. So up to 60% relative humidity at 68 degrees (53 degree dew point), and as low as 20% humidity at 76 degrees (32 degree dew point). Even that is a huge range, and 32 is about the lowest the dew point can be without pronounced dry air effects such as dry skin, eyes, and bloody noses, etc. And the calculation of a 60 degree dew point at 76 degrees is almost a subtropical outdoor summer amount of humidity. Also consider that more humidity can to some degree make up for cooler air, so a 60 degree dew point at about 70-72 degrees is more comfortable than 60DP/60% humidity at 76 degrees. 20% humidity is very low for the entire range of room temps given, let alone 20% at 68 degrees, which is a 26 deg dew point. Also a factor is that a humidity level above the minimum for comfort may be needed indoors in the cold or winter months to make up for arctic dew points and wind exposure outdoors. The whole article isn't up to good par, and has the tags to show. I may get into fixing this myself and adding some more research and sources. B137 ( talk) 18:56, 4 November 2016 (UTC)

I would think that 99.9% of the time that anyone is concerned about water content in ambient air they want to know "Will it be hot and humid, or will it be hot and dry?". How many people need to ask what the humidity will be on a comfortable day or even a cold day? So who gives a hoot about "dew" when it is hot? Who is thinking about dew and not about HUMIDITY?
So my point is that there should be a brief explanation of why DP is a better metric in a weather forecast or condition because I notice that all of our weather people forecast in DP values and I really doubt that many people understand or care about this. 76.168.51.241 ( talk) 17:56, 10 August 2017 (UTC)
This seems to be the consensus among weather professionals. Can you explain to the lay readers WHY this is so?

"Dew point temperature is never greater than the air temperature because relative humidity cannot exceed 100%."
<--------->
"At temperatures below the dew point, the rate of condensation will be greater than that of evaporation, forming more liquid water."
(Emphases by me.)
How is this not a contradiction? Can somebody explain?
74.93.186.81 ( talk) 19:44, 9 December 2017 (UTC)
I noticed this and believe it is a contradiction as well. I believe the author might have meant that dew point cannot STABLY be greater than temperature. So if the temperature of humid air suddenly drops below the dew point, water will begin to condense, but there might be a period of time where the water has not finished condensing yet. During that period of time, the dew point is greater than the temperature but the dew point is not stable since water will continue to condense until the dew point equals the temperature. Can anyone confirm if this is correct? If it is, is there a way to calculate how long the condensation process takes at various temperatures and dew points? — Preceding

"A well-known approximation used to calculate the dew point, Tdp, given just the actual ("dry bulb") air temperature, T (in degrees Celsius) and relative humidity (in percent), RH, is the Magnus formula: "
