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
23 years with a frostAcross 23 years with a frost, the median last spring frost at Randolph falls on 21 June and the median first autumn frost on 24 August, which leaves a median of 63 days between them.
| Measure | Median, all years | Earliest period | Recent period (1983 to 2025) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 21 June | n/a | 21 June | n/a | n/a |
| First autumn frost | 24 August | n/a | 24 August | n/a | n/a |
| Growing days | 63 days | n/a | 63 days | n/a | n/a |
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
44 years, 1905 to 2025A day with at least 23.9 mm (0.9 in) of rain is expected about once in 2 years. A day with at least 52.5 mm (2.1 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 23.9 mm (0.9 in) | |
| 5 years | 31.5 mm (1.2 in) | |
| 10 years | 36.5 mm (1.4 in) | |
| 25 years | 42.9 mm (1.7 in) | |
| 50 years | 47.7 mm (1.9 in) | Longer than the 44 years of record |
| 100 years | 52.5 mm (2.1 in) | Longer than the 44 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, 44 years of values from 1905 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: 46.0 mm (1.8 in) in 1997; 45.7 mm (1.8 in) in 2014; 44.5 mm (1.8 in) in 1906.
