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

60 years with a frost

Across 60 years with a frost, the median last spring frost at Fenn Rs falls on 30 April and the median first autumn frost on 12 October, which leaves a median of 172 days between them.

In 1980 to 2025 the median growing season was 175 days. That is 8 days more than in 1940 to 1979.

Fitted over all years, the growing season changes by +2.6 days per decade at this station.

First autumn frost12 October10 October14 October4 days later+2.2 days per decade
Growing days172 days167 days175 days8 days more+2.6 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, 1940 to 2018

A day with at least 37.3 mm (1.5 in) of rain is expected about once in 2 years. A day with at least 64.7 mm (2.5 in) of rain is expected about once in 100 years.

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 1940 to 2018.

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: 63.5 mm (2.5 in) in 1984; 63.5 mm (2.5 in) in 2017; 58.4 mm (2.3 in) in 1977.

Station Changes

No change in the annual mean temperature of this station was found against its neighbours.

Climate Twins

2003 to 2025 against 1961 to 1990

Over 2003 to 2025, Fenn Rs had a mean temperature of 9.9 C (49.7 F) and 1,100.3 mm (43.3 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Hells Gate (Canada, 601 km away), Novo Mesto (Slovenia, 8,718 km away) and Elkins- Randolph Co AP (United States, 3,006 km away).

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.
