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

40 years with a frost

Across 40 years with a frost, the median last spring frost at Cutler Dam falls on 2 May and the median first autumn frost on 17 October, which leaves a median of 170 days between them.

Fitted over all years, the growing season changes by +2.8 days per decade at this station.

First autumn frost17 Octobern/a17 Octobern/a+1.3 days per decade
Growing days170 daysn/a172 daysn/a+2.8 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

42 years, 1981 to 2025

A day with at least 28.2 mm (1.1 in) of rain is expected about once in 2 years. A day with at least 84.6 mm (3.3 in) of rain is expected about once in 100 years.

50 years70.6 mm (2.8 in)Longer than the 42 years of record
100 years84.6 mm (3.3 in)Longer than the 42 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, 42 years of values from 1981 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: 80.8 mm (3.2 in) in 2005; 63.5 mm (2.5 in) in 2019; 61.0 mm (2.4 in) in 1982.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Cutler Dam, at 2008. Each is measured against neighbouring stations.

  • Relative to 5 neighbouring stations, the station's annual mean temperature from 2008 ran 0.5 C (0.8 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.
