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
67 years with a frostAcross 67 years with a frost, the median last spring frost at Corcoran Irrig Dist falls on 28 February and the median first autumn frost on 24 November, which leaves a median of 274 days between them.
In 1988 to 2023 the median growing season was 288 days. That is 41 days more than in 1949 to 1979.
Fitted over all years, the growing season changes by +8.4 days per decade at this station.
| Measure | Median, all years | Earliest period (1949 to 1979) | Recent period (1988 to 2023) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 28 February | 13 March | 10 February | 31 days earlier | -6.4 days per decade |
| First autumn frost | 24 November | 18 November | 26 November | 8 days later | +2.0 days per decade |
| Growing days | 274 days | 247 days | 288 days | 41 days more | +8.4 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
73 years, 1949 to 2025A day with at least 22.4 mm (0.9 in) of rain is expected about once in 2 years. A day with at least 65.0 mm (2.6 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 22.4 mm (0.9 in) | |
| 5 years | 31.6 mm (1.2 in) | |
| 10 years | 38.5 mm (1.5 in) | |
| 25 years | 48.2 mm (1.9 in) | |
| 50 years | 56.3 mm (2.2 in) | |
| 100 years | 65.0 mm (2.6 in) | Longer than the 73 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, 73 years of values from 1949 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: 78.7 mm (3.1 in) in 2023; 52.1 mm (2.1 in) in 2006; 49.0 mm (1.9 in) in 1969.

Climate Twins
2004 to 2023 against 1961 to 1990Over 2004 to 2023, Corcoran Irrig Dist had a mean temperature of 18.0 C (64.4 F) and 179.9 mm (7.1 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Maricopa (United States, 114 km away), Tejon Rancho (United States, 141 km away) and San Manuel (United States, 909 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Maricopa | United States | 114 km (71 mi) | 18.2 C (64.7 F) | 147.5 mm (5.8 in) | 0.51 |
| Tejon Rancho | United States | 141 km (88 mi) | 17.5 C (63.4 F) | 273.4 mm (10.8 in) | 0.85 |
| San Manuel | United States | 909 km (565 mi) | 18.3 C (64.9 F) | 337.6 mm (13.3 in) | 0.90 |
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.
