The year, day by day
The year in Placerville runs from a mild 33°F around December 21 to 95°F at the peak near July 23, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from June 28 through September 6, covering 71 dates. The broader mild season, normal highs of 70°F or more, runs April 27 to November 2.
This counts calendar dates whose 1991–2020 normal high reaches 90°F. It is a smaller number than the 90°F+ day counts in the monthly table above, which measure how often the threshold was actually crossed in a typical year. A date can average 88°F and still exceed 90°F in half of all years.
No freezing date
Not one calendar date in the 1991–2020 record carries a normal low at or below 32°F. The coldest normal low of the year is 33°F around December 21.
The widest day
August 2 carries the biggest normal gap between afternoon and dawn, 34°F between the normal high and the normal low.

Data-derived climate profile
How Placerville's climate pattern fits together
heating led · mid swing
Placerville's energy balance leans toward cold weather: 3,176 annual heating degree days against 1,300 for cooling. Its 32.4°F seasonal range still makes the monthly rows more useful than the annual average alone.
Placerville's frost-free season lasts about 235 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
July and December mark the typical warm and cold ends of the calendar in Placerville's middle-range seasonal profile. The measured spread is 32.4°F. The annual average is 60°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
A moisture-range label is withheld because Placerville's annual precipitation total is unavailable. Monthly source values remain visible where NOAA provides them, and no annual amount is reconstructed from incomplete data.
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.
