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

85 years with a frost

Across 85 years with a frost, the median last spring frost at Anacortes falls on 21 March and the median first autumn frost on 11 November, which leaves a median of 233 days between them.

In 1977 to 2013 the median growing season was 255 days. That is 24 days more than in 1905 to 1948.

Fitted over all years, the growing season changes by +3.1 days per decade at this station.

Frost dates and growing season at Anacortes
Measure	Median, all years	Earliest period (1905 to 1948)	Recent period (1977 to 2013)	Recent against earliest	Fitted trend
Last spring frost	21 March	30 March	7 March	23 days earlier	-2.7 days per decade
First autumn frost	11 November	12 November	12 November	no change	+0.4 days per decade
Growing days	233 days	231 days	255 days	24 days more	+3.1 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

98 years, 1894 to 2014

A day with at least 29.5 mm (1.2 in) of rain is expected about once in 2 years. A day with at least 71.0 mm (2.8 in) of rain is expected about once in 100 years.

Rainfall return levels at Anacortes: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	29.5 mm (1.2 in)
5 years	38.5 mm (1.5 in)
10 years	45.3 mm (1.8 in)
25 years	54.7 mm (2.2 in)
50 years	62.5 mm (2.5 in)
100 years	71.0 mm (2.8 in)	Longer than the 98 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, 98 years of values from 1894 to 2014.

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: 76.2 mm (3.0 in) in 1949; 63.5 mm (2.5 in) in 1945; 59.7 mm (2.4 in) in 1956.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Anacortes, at 1958. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1958 ran 0.3 C (0.5 F) lower than in the years before (possible change).

Suspected changes in the annual mean temperature at Anacortes, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1958	-0.2	-0.4	possible	5

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.
