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

80 years with a frost

Across 80 years with a frost, the median last spring frost at Valley falls on 27 March and the median first autumn frost on 23 November, which leaves a median of 244 days between them.

In 1992 to 2025 the median growing season was 253 days. That is 16 days more than in 1933 to 1970.

Fitted over all years, the growing season changes by +3.7 days per decade at this station.

Frost dates and growing season at Valley

First autumn frost23 November18 November29 November11 days later+1.4 days per decade
Growing days244 days237 days253 days16 days more+3.7 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, 1973 to 2025

A day with at least 32.3 mm (1.3 in) of rain is expected about once in 2 years. A day with at least 62.3 mm (2.5 in) of rain is expected about once in 100 years.

50 years57.8 mm (2.3 in)Longer than the 39 years of record
100 years62.3 mm (2.5 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 1973 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: 58.6 mm (2.3 in) in 2014; 54.0 mm (2.1 in) in 2021; 49.3 mm (1.9 in) in 2013.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Valley, at 1994. Each is measured against neighbouring stations.

  • Relative to 5 neighbouring stations, the station's annual mean temperature from 1994 ran 0.1 C (0.2 F) lower than in the years before (likely change).

Possible change at the station (a move, a new instrument or a new site); the record is kept as measured. A "likely" change has a larger test statistic than a "possible" one. Neither says why the station differs from its neighbours. How changes are found, and the largest ones.
