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
35 years with a frostAcross 35 years with a frost, the median last spring frost at Morrisville-Stowe State AP falls on 25 May and the median first autumn frost on 20 September, which leaves a median of 125 days between them.
Fitted over all years, the growing season changes by +5.4 days per decade at this station.
| Measure | Median, all years | Earliest period | Recent period (1968 to 2025) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 25 May | n/a | 21 May | n/a | -3.0 days per decade |
| First autumn frost | 20 September | n/a | 25 September | n/a | +2.4 days per decade |
| Growing days | 125 days | n/a | 128 days | n/a | +5.4 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
39 years, 1963 to 2025A day with at least 51.4 mm (2.0 in) of rain is expected about once in 2 years. A day with at least 125.9 mm (5.0 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 51.4 mm (2.0 in) | |
| 5 years | 69.5 mm (2.7 in) | |
| 10 years | 82.2 mm (3.2 in) | |
| 25 years | 99.1 mm (3.9 in) | |
| 50 years | 112.2 mm (4.4 in) | Longer than the 39 years of record |
| 100 years | 125.9 mm (5.0 in) | Longer than the 39 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, 39 years of values from 1963 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: 108.7 mm (4.3 in) in 1995; 106.7 mm (4.2 in) in 1999; 93.0 mm (3.7 in) in 1977.
Climate Twins
2002 to 2025 against 1961 to 1990Over 2002 to 2025, Morrisville-Stowe State AP had a mean temperature of 6.1 C (43.1 F) and 1,056.5 mm (41.6 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Rumford 1 SSE (United States, 165 km away), Woodland (United States, 417 km away) and Chasm Falls (United States, 129 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Rumford 1 SSE | United States | 165 km (103 mi) | 6.3 C (43.4 F) | 1,091.6 mm (43.0 in) | 0.60 |
| Woodland | United States | 417 km (259 mi) | 6.2 C (43.2 F) | 1,130.4 mm (44.5 in) | 0.61 |
| Chasm Falls | United States | 129 km (80 mi) | 5.9 C (42.7 F) | 1,097.3 mm (43.2 in) | 0.63 |
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.
