The year, day by day
Summer here tops out rather than builds: the warmest normal high is 84°F around July 6, short of 90°F on every date, while 208 dates carry a normal low at or below freezing, the coldest 12°F near December 24.
The freezing stretch
The normal low stays at or below 32°F into May 5, then returns to freezing around October 11, covering 208 dates in all.
Derived from the normal daily minimum. This is a different measure from the 50%-probability frost dates shown elsewhere on this page, which come from NOAA’s frost product.
The widest day
June 16 carries the biggest normal gap between afternoon and dawn, 36°F between the normal high and the normal low.

Where Placerville Stands Nationally
Winters bite deep and often: the normal nightly low dips to freezing or below on around 208 nights a year, placing this among the most frost-prone tenth of ranked stations.
Daily temperature swings run wider than most of the country, peaking near 36°F between the normal high and low.
Placerville earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.
Monthly Precipitation
Average monthly rainfall
Placerville spreads its precipitation across the year
Neither half of the year dominates here: June through August take 27% of the annual total and December through February 19%, with neither reaching the 35% that would mark a distinct wet season. Placerville has no dry season to plan around, though it does carry a 40.4°F seasonal spread.
The gap between the wettest and driest month still matters: August averages 2.6" and June 0.8". The three wettest months together take 35% of the year, against the 25% a perfectly flat distribution would give them.
Shares are computed from this station's own 1991-2020 monthly precipitation normals. "Spread across the year" means neither the June-August nor the December-February share reaches 35%; it describes an average year, not the variability of any single one.

Data-derived climate profile
How Placerville's climate pattern fits together
heating led · moderate · mid swing
Placerville's energy balance leans toward cold weather: 7,280 annual heating degree days against 154 for cooling. Its 40.4°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 126 days are frost-free in a normal year. That short interval is consistent with the cold-season signal, but the measure does not predict the exact first or last freeze in any one year.
July and January mark the typical warm and cold ends of the calendar in Placerville's middle-range seasonal profile. The measured spread is 40.4°F. The annual average is 45°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Placerville's 21.5 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Snowfall is not added to the interpretation because its annual value is missing. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
These labels group NOAA 1991-2020 normals from Placerville's primary station, so the winter figures are a thirty-year average and not a floor: a single hard season can run well below them. Treat each band as a descriptive range for Placerville, not an official NOAA class or a year-ahead forecast.
