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

34 years with a frost

Across 34 years with a frost, the median last spring frost at Stillwater Creek falls on 13 June and the median first autumn frost on 13 September, which leaves a median of 91 days between them.

Fitted over all years, the growing season changes by +13.3 days per decade at this station.

First autumn frost13 Septembern/a13 Septembern/a+9.3 days per decade
Growing days91 daysn/a92 daysn/a+13.3 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

40 years, 1986 to 2025

A day with at least 20.2 mm (0.8 in) of rain is expected about once in 2 years. A day with at least 42.0 mm (1.7 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, 40 years of values from 1986 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: 33.0 mm (1.3 in) in 1986; 33.0 mm (1.3 in) in 2003; 33.0 mm (1.3 in) in 2025.
