The annual mean temperature here has risen by 0.5 C (0.4 to 0.6) per decade over 1938 to 2025. In Fahrenheit: 0.9 F (0.8 to 1.0) per decade. The slope is a straight line fitted to 88 complete years; the brackets give its 95 percent interval.
| Measure | Per decade (C) | Per decade (F) | Period | Complete years | Reading |
|---|---|---|---|---|---|
| Annual mean temperature | 0.5 C (0.4 to 0.6) per decade | 0.9 F (0.8 to 1.0) per decade | 1938 to 2025 | 88 | Rise |
| Mean daily maximum | 0.2 C (0.1 to 0.2) per decade | 0.3 F (0.2 to 0.4) per decade | 1938 to 2025 | 88 | Rise |
| Mean daily minimum | 0.8 C (0.7 to 0.9) per decade | 1.5 F (1.3 to 1.6) per decade | 1938 to 2025 | 88 | 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
88 years with a frostAcross 88 years with a frost, the median last spring frost at Reno AP falls on 18 May and the median first autumn frost on 5 October, which leaves a median of 135 days between them.
In 1996 to 2025 the median growing season was 182 days. That is 75 days more than in 1938 to 1967.
Fitted over all years, the growing season changes by +12.5 days per decade at this station.
| Measure | Median, all years | Earliest period (1938 to 1967) | Recent period (1996 to 2025) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 18 May | 4 June | 20 April | 45 days earlier | -6.8 days per decade |
| First autumn frost | 5 October | 18 September | 19 October | 31 days later | +5.7 days per decade |
| Growing days | 135 days | 107 days | 182 days | 75 days more | +12.5 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
88 years, 1938 to 2025A day with at least 23.3 mm (0.9 in) of rain is expected about once in 2 years. A day with at least 63.2 mm (2.5 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 23.3 mm (0.9 in) | |
| 5 years | 33.3 mm (1.3 in) | |
| 10 years | 40.2 mm (1.6 in) | |
| 25 years | 49.2 mm (1.9 in) | |
| 50 years | 56.2 mm (2.2 in) | |
| 100 years | 63.2 mm (2.5 in) | Longer than the 88 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, 88 years of values from 1938 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: 58.2 mm (2.3 in) in 1943; 57.4 mm (2.3 in) in 2022; 51.3 mm (2.0 in) in 1955.
Station Changes
1 suspectedOne change was suspected in the annual mean temperature of Reno AP, at 1999. Each is measured against neighbouring stations.
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1999 ran 1.0 C (1.9 F) higher than in the years before (likely change).
| Year | Shift (C) | Shift (F) | Strength | Neighbours |
|---|---|---|---|---|
| 1999 | +1.0 | +1.9 | 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, Reno AP had a mean temperature of 13.2 C (55.7 F) and 200.2 mm (7.9 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Hawthorne AP (United States, 143 km away), Bishop AP (United States, 267 km away) and Colorado City (United States, 656 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Hawthorne AP | United States | 143 km (89 mi) | 12.7 C (54.9 F) | 127.8 mm (5.0 in) | 0.80 |
| Bishop AP | United States | 267 km (166 mi) | 13.3 C (55.9 F) | 136.6 mm (5.4 in) | 0.80 |
| Colorado City | United States | 656 km (408 mi) | 12.7 C (54.9 F) | 319.0 mm (12.6 in) | 0.87 |
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.
