Each chart shows one value per year; the dot marks the record year. TXx is the hottest daily maximum, TNn the coldest daily minimum, Rx1day and Rx5day the largest one-day and five-day rain totals, and CDD the longest run of days with less than 1 mm of rain. A year with missing days can understate an extreme.

Frost Dates and Growing Season

56 years with a frost

Across 56 years with a frost, the median last spring frost at Idyllwild Fire Dept falls on 24 May and the median first autumn frost on 13 October, which leaves a median of 139 days between them.

Fitted over all years, the growing season changes by +6.0 days per decade at this station.

Frost dates and growing season at Idyllwild Fire Dept
Measure	Median, all years	Earliest period	Recent period (1991 to 2025)	Recent against earliest	Fitted trend
Last spring frost	24 May	n/a	21 May	n/a	-2.9 days per decade
First autumn frost	13 October	n/a	21 October	n/a	+3.1 days per decade
Growing days	139 days	n/a	151 days	n/a	+6.0 days per decade

A frost day is a day with a daily minimum at or below 0 C (32 F). The last spring frost and the first autumn frost are the last and first such days of the cold season, and growing days are the days between them. A negative trend for the last spring frost means it comes earlier.

Rainfall Return Levels

77 years, 1946 to 2025

A day with at least 65.0 mm (2.6 in) of rain is expected about once in 2 years. A day with at least 197.9 mm (7.8 in) of rain is expected about once in 100 years.

Rainfall return levels at Idyllwild Fire Dept: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	65.0 mm (2.6 in)
5 years	92.0 mm (3.6 in)
10 years	112.8 mm (4.4 in)
25 years	143.2 mm (5.6 in)
50 years	169.0 mm (6.7 in)
100 years	197.9 mm (7.8 in)	Longer than the 77 years of record

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 77 years of values from 1946 to 2025.

A return level is an estimate. It is least reliable for the long periods, 50 and 100 years, and for any period longer than the record behind the fit, where the fit has to reach past the largest day actually observed. It is not a forecast.

The largest wettest-day totals in the fit: 179.6 mm (7.1 in) in 2019; 169.2 mm (6.7 in) in 1966; 154.7 mm (6.1 in) in 1991.

Climate Twins

2011 to 2025 against 1961 to 1990

Twins are stations, not cities. A twin is one of the three stations at least 100 km away whose earlier climate is closest to this station's recent one, so a close match does not mean the two places look alike in other ways. A station move or a gap in a record can change that station's averages. The list describes past climate; it is not a forecast and does not say what caused any change. How twins are found, and a search for any station.
