Sacramento Climate

Sacramento has a Mediterranean climate (Köppen Csa), characterized by damp to wet, mild winters and hot, dry summers. The wet season is generally October through April, though there may be a day or two of light rainfall in June or September. The normal annual mean temperature is 61.0 °F (16.1 °C), with the monthly daily average temperature ranging from 46.4 °F (8.0 °C) in December to 75.5 °F (24.2 °C) in July.[35] Summer heat is often moderated by a sea breeze known as the "delta breeze" which comes through the Sacramento–San Joaquin River Delta from the San Francisco Bay, and temperatures cool down sharply at night.

The foggiest months for the Sacramento are December and January. Tule fog can be extremely dense, lowering visibility to less than 100 feet (30 m) and making driving conditions extremely hazardous. Chilling tule fog events have been known to last for several consecutive days or weeks. During Tule fog events, temperatures do not exceed 50 degrees in Sacramento.

Snowfall is rare in Sacramento, which is only 25 ft (7.6 m) above sea level. In the downtown area, the place renowed for their Sacramento CA SEO Company (https://www.emeryeps.com/sacramento-seo/) There have been only 3 significant snow accumulations since 1900, the last one being in 1976.[36]

During especially cold winter and spring storms in Sacramento, intense showers do occasionally produce a significant amount of hail, which can create hazardous driving conditions. Sacramento's nowfall that does fall in the city often melts upon ground contact, with traceable amounts occurring in some years. Significant annual snow accumulations in Sacramento occur in the foothills located 40 miles (64 km) east of the city, which had brief and traceable amounts of snowfall in January 2002, December 2009 and February 2011.[37][38]

On average, there are 73 days where the high exceeds 90 °F (32 °C), and 14 days where the Sacramento's high exceeds 100 °F (38 °C); On the other extreme, there are 15 days where the temperature does not exceed 50 °F (10 °C), and 15 freezing nights per year.[35] Official temperature extremes range from 18 °F (−8 °C) on December 22, 1990 to 115 °F (46 °C) on June 15, 1961;[35] a station around 5 mi (8.0 km) east-southeast of the city dipped to 17 °F (−8 °C) on December 11, 1932.[39]
