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
66 years with a frostAcross 66 years with a frost, the median last spring frost at Princeton falls on 21 April and the median first autumn frost on 10 October, which leaves a median of 172 days between them.
In 1980 to 2025 the median growing season was 174 days. That is 6 days more than in 1893 to 1972.
Fitted over all years, the growing season changes by -0.2 days per decade at this station.
| Measure | Median, all years | Earliest period (1893 to 1972) | Recent period (1980 to 2025) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 21 April | 25 April | 20 April | 5 days earlier | +0.4 days per decade |
| First autumn frost | 10 October | 9 October | 12 October | 3 days later | +0.2 days per decade |
| Growing days | 172 days | 168 days | 174 days | 6 days more | -0.2 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
70 years, 1894 to 2022A day with at least 70.4 mm (2.8 in) of rain is expected about once in 2 years. A day with at least 154.1 mm (6.1 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 70.4 mm (2.8 in) | |
| 5 years | 93.7 mm (3.7 in) | |
| 10 years | 108.7 mm (4.3 in) | |
| 25 years | 127.4 mm (5.0 in) | |
| 50 years | 140.9 mm (5.5 in) | |
| 100 years | 154.1 mm (6.1 in) | Longer than the 70 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, 70 years of values from 1894 to 2022.
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: 160.0 mm (6.3 in) in 2021; 137.7 mm (5.4 in) in 1993; 137.2 mm (5.4 in) in 1992.

No change in the annual mean temperature of this station was found against its neighbours.
Climate Twins
1998 to 2025 against 1961 to 1990Over 1998 to 2025, Princeton had a mean temperature of 11.3 C (52.3 F) and 835.2 mm (32.9 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Dayton Intl AP (United States, 797 km away), Indianapolis SE Side (United States, 644 km away) and Springfield Abraham Lincoln Ca (United States, 337 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Dayton Intl AP | United States | 797 km (495 mi) | 11.0 C (51.7 F) | 931.4 mm (36.7 in) | 0.71 |
| Indianapolis SE Side | United States | 644 km (400 mi) | 11.2 C (52.2 F) | 977.3 mm (38.5 in) | 0.71 |
| Springfield Abraham Lincoln Ca | United States | 337 km (209 mi) | 11.4 C (52.5 F) | 896.4 mm (35.3 in) | 0.72 |
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.
