Climate
El Dorado Hills has a Mediterranean climate, with hot, dry summers and cool, wet winters. The hottest month is July, with average high temperatures around 97°F (36°C), and the coldest is January, with average highs near 56°F (13°C) and lows around 38°F (3°C).
December and January are the months with the lowest average minimum temperatures, typically in the upper 30s°F (3–4°C).
The average annual rainfall is about 23 inches (585 mm), though this can vary significantly year to year due to ongoing drought conditions and climate variability. The wettest months are typically January and February, each averaging about 4–5 inches (100–125 mm) of rain.
Frost is common in winter, but snowfalls remain rare, although occasional light dustings have been reported in recent years. Drought and wildfire risk have increased in the 2020s, especially during late summer and fall.
Prevailing winds are generally from the south and southwest, but strong, dry northerly winds (including "Diablo winds") can occur in autumn, increasing wildfire danger.
The nearest official weather stations are at Folsom Dam (northwest of El Dorado Hills) and at Placerville. Local microclimates can cause some variation in temperature and precipitation across the area.

About this topic
- Accuracy
The climate description aligns with current records: Mediterranean conditions, hot dry summers, cool wet winters, and typical temperatures ranging from 97°F (36°C) in July to 38°F (3°C) in January are well-supported by recent data. Average rainfall near 23 inches (585 mm) and winter minimums in the upper 30s°F are consistent with official weather station reports.
Notes on frost, rare snowfall, increased drought, wildfire risk, and prevailing winds (including "Diablo winds") match observed trends for the region throughout the 2020s. Reference to Folsom Dam and Placerville stations and mention of microclimate effects are also correct and relevant.
