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

68 years with a frost

Across 68 years with a frost, the median last spring frost at Seaside falls on 10 April and the median first autumn frost on 7 November, which leaves a median of 216 days between them.

In 1971 to 2017 the median growing season was 222 days. That is 16 days more than in 1931 to 1962.

Fitted over all years, the growing season changes by +2.2 days per decade at this station.

First autumn frost7 November7 November6 November1 day earlier+0.9 days per decade
Growing days216 days206 days222 days16 days more+2.2 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

73 years, 1930 to 2024

A day with at least 74.1 mm (2.9 in) of rain is expected about once in 2 years. A day with at least 131.6 mm (5.2 in) of rain is expected about once in 100 years.

50 years123.3 mm (4.9 in)
100 years131.6 mm (5.2 in)Longer than the 73 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, 73 years of values from 1930 to 2024.

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: 139.7 mm (5.5 in) in 2023; 119.9 mm (4.7 in) in 2015; 106.9 mm (4.2 in) in 1936.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Seaside, at 1992. Each is measured against neighbouring stations.

  • Relative to 5 neighbouring stations, the station's annual mean temperature from 1992 ran 0.4 C (0.8 F) lower than in the years before (likely change).

YearShift (C)Shift (F)StrengthNeighbours

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.
