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

81 years with a frost

Across 81 years with a frost, the median last spring frost at Grangeville falls on 19 May and the median first autumn frost on 21 September, which leaves a median of 127 days between them.

In 1978 to 2025 the median growing season was 133 days. That is 6 days more than in 1894 to 1955.

Fitted over all years, the growing season changes by +1.0 days per decade at this station.

First autumn frost21 September22 September24 September2 days later+0.4 days per decade
Growing days127 days127 days133 days6 days more+1.0 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

89 years, 1894 to 2025

A day with at least 30.9 mm (1.2 in) of rain is expected about once in 2 years. A day with at least 62.1 mm (2.4 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, 89 years of values from 1894 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: 76.5 mm (3.0 in) in 1955; 53.6 mm (2.1 in) in 1997; 50.8 mm (2.0 in) in 1985.
