The annual mean temperature here has risen by 0.2 C (0.1 to 0.2) per decade over 1932 to 2025. In Fahrenheit: 0.3 F (0.2 to 0.4) per decade. The slope is a straight line fitted to 91 complete years; the brackets give its 95 percent interval.
| Measure | Per decade (C) | Per decade (F) | Period | Complete years | Reading |
|---|---|---|---|---|---|
| Annual mean temperature | 0.2 C (0.1 to 0.2) per decade | 0.3 F (0.2 to 0.4) per decade | 1932 to 2025 | 91 | Rise |
| Mean daily maximum | -0.04 C (-0.10 to 0.01) per decade | -0.08 F (-0.17 to 0.01) per decade | 1932 to 2025 | 91 | Not clearly different from zero |
| Mean daily minimum | 0.4 C (0.3 to 0.4) per decade | 0.7 F (0.6 to 0.8) per decade | 1932 to 2025 | 91 | Rise |
A year is complete when all 12 months have at least 20 days of both daily maximum and daily minimum readings. The annual mean is the mean of the monthly means. The trend describes this one station over this period; it does not say what caused the change.

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
84 years with a frostAcross 84 years with a frost, the median last spring frost at Los Banos falls on 23 February and the median first autumn frost on 26 November, which leaves a median of 278 days between them.
In 1988 to 2022 the median growing season was 300 days. That is 51 days more than in 1932 to 1963.
Fitted over all years, the growing season changes by +8.5 days per decade at this station.
| Measure | Median, all years | Earliest period (1932 to 1963) | Recent period (1988 to 2022) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 23 February | 12 March | 6 February | 34 days earlier | -5.1 days per decade |
| First autumn frost | 26 November | 17 November | 3 December | 16 days later | +3.3 days per decade |
| Growing days | 278 days | 249 days | 300 days | 51 days more | +8.5 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
98 years, 1908 to 2025A day with at least 25.2 mm (1.0 in) of rain is expected about once in 2 years. A day with at least 57.1 mm (2.2 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 25.2 mm (1.0 in) | |
| 5 years | 33.8 mm (1.3 in) | |
| 10 years | 39.5 mm (1.6 in) | |
| 25 years | 46.7 mm (1.8 in) | |
| 50 years | 51.9 mm (2.0 in) | |
| 100 years | 57.1 mm (2.2 in) | Longer than the 98 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, 98 years of values from 1908 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: 57.2 mm (2.3 in) in 1983; 57.2 mm (2.3 in) in 2019; 53.6 mm (2.1 in) in 2021.
Station Changes
2 suspected2 changes were suspected in the annual mean temperature of Los Banos, at 1969 and 1984. Each is measured against neighbouring stations.
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1969 ran 0.2 C (0.4 F) lower than in the years before (possible change).
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1984 ran 0.3 C (0.5 F) lower than in the years before (likely change).
| Year | Shift (C) | Shift (F) | Strength | Neighbours |
|---|---|---|---|---|
| 1969 | -0.2 | -0.4 | possible | 5 |
| 1984 | -0.3 | -0.5 | likely | 5 |
Possible change at the station (a move, a new instrument or a new site); the record is kept as measured. A "likely" change has a larger test statistic than a "possible" one. Neither says why the station differs from its neighbours. How changes are found, and the largest ones.
Climate Twins
2011 to 2025 against 1961 to 1990Over 2011 to 2025, Los Banos had a mean temperature of 17.9 C (64.2 F) and 212.0 mm (8.3 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Porterville (United States, 198 km away), Coalinga (United States, 112 km away) and Tejon Rancho (United States, 296 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Porterville | United States | 198 km (123 mi) | 17.7 C (63.9 F) | 280.0 mm (11.0 in) | 0.68 |
| Coalinga | United States | 112 km (70 mi) | 17.6 C (63.7 F) | 190.8 mm (7.5 in) | 0.74 |
| Tejon Rancho | United States | 296 km (184 mi) | 17.5 C (63.4 F) | 273.4 mm (10.8 in) | 0.89 |
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.
