The North Columbia River east of Savona

Savona has a temperate desert climate (Köppen BWk) with hot, dry summers and mild, short winters with four distinct seasons. Being just north of the 40th parallel, Savona is rather temperate for a desert climate, but temperatures in the summertime can reach extreme highs on occasion. Summer is considered to be from May to September, with precipitation peaking in May and June. Daytime temperatures can often reach 40°C (104°F) during the summer months, sometimes reaching as high as 50°C (122°F). High temperatures usually hover in the 30°C-38°C (86°F-100°F) range. Nights, however, are usually cool, and the humidity remains low during the daytime. Drought conditions can prevail during the summer time, making wildfires a problem in the region. Thunderstorms are most common from April to October, and some storms can be severe, although tornadoes are extremely rare. Winters are sunny and mild, with little snowfall. With temperatures rarely dropping below freezing, this allows for a growing season of almost 9 months. Spring and autumn are warm transition seasons. The warm climate year round allows for agriculture and viticulture in the area, as Savona and the surrounding area in the Sendaro Valley is one of the top wine producers in the world.

Savona, with over 4,000 hours of sunshine, is the sunniest city in Cascadia and one of the sunniest on the continent, due to dry southernly winds that prevail for most of the year, keeping precipitation and clouds to a minimum. The hottest temperature ever in Savona, which is also the hottest temperature ever recorded in Cascadia, is 50.5°C (122.9°F), recorded on August 8th, 2012, while the coldest temperature, -16.3°C (2.7°F), was recorded on January 14th, 1980. Savona is located in USDA Plant Hardiness Zone 9a.
