The annual mean temperature here has risen by 0.1 C (0.1 to 0.1) per decade over 1893 to 2025. In Fahrenheit: 0.2 F (0.1 to 0.2) per decade. The slope is a straight line fitted to 127 complete years; the brackets give its 95 percent interval.
| Measure | Per decade (C) | Per decade (F) | Period | Complete years | Reading |
|---|---|---|---|---|---|
| Annual mean temperature | 0.1 C (0.1 to 0.1) per decade | 0.2 F (0.1 to 0.2) per decade | 1893 to 2025 | 127 | Rise |
| Mean daily maximum | 0.08 C (0.05 to 0.12) per decade | 0.1 F (0.1 to 0.2) per decade | 1893 to 2025 | 127 | Rise |
| Mean daily minimum | 0.1 C (0.1 to 0.1) per decade | 0.2 F (0.1 to 0.2) per decade | 1893 to 2025 | 127 | 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
127 years with a frostAcross 127 years with a frost, the median last spring frost at Keene falls on 17 May and the median first autumn frost on 23 September, which leaves a median of 128 days between them.
In 1992 to 2025 the median growing season was 146 days. That is 29 days more than in 1893 to 1922.
Fitted over all years, the growing season changes by +2.9 days per decade at this station.
| Measure | Median, all years | Earliest period (1893 to 1922) | Recent period (1992 to 2025) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 17 May | 23 May | 14 May | 9 days earlier | -1.3 days per decade |
| First autumn frost | 23 September | 20 September | 6 October | 16 days later | +1.6 days per decade |
| Growing days | 128 days | 117 days | 146 days | 29 days more | +2.9 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
110 years, 1893 to 2025A day with at least 55.0 mm (2.2 in) of rain is expected about once in 2 years. A day with at least 139.5 mm (5.5 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 55.0 mm (2.2 in) | |
| 5 years | 72.2 mm (2.8 in) | |
| 10 years | 85.5 mm (3.4 in) | |
| 25 years | 104.9 mm (4.1 in) | |
| 50 years | 121.3 mm (4.8 in) | |
| 100 years | 139.5 mm (5.5 in) |
The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 110 years of values from 1893 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: 219.5 mm (8.6 in) in 2005; 111.0 mm (4.4 in) in 1999; 103.1 mm (4.1 in) in 2021.

Climate Twins
2011 to 2025 against 1961 to 1990Over 2011 to 2025, Keene had a mean temperature of 8.2 C (46.7 F) and 1,181.6 mm (46.5 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Sanford 2 NNW (United States, 138 km away), Lewiston (United States, 213 km away) and Epping (United States, 101 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Sanford 2 NNW | United States | 138 km (86 mi) | 8.1 C (46.6 F) | 1,193.1 mm (47.0 in) | 0.57 |
| Lewiston | United States | 213 km (132 mi) | 7.8 C (46.1 F) | 1,149.9 mm (45.3 in) | 0.74 |
| Epping | United States | 101 km (63 mi) | 8.1 C (46.6 F) | 1,117.3 mm (44.0 in) | 0.75 |
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.
