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
55 years with a frost
Across 55 years with a frost, the median last spring frost at Washington Sp falls on 8 March and the median first autumn frost on 21 November, which leaves a median of 261 days between them.
Fitted over all years, the growing season changes by -2.1 days per decade at this station.

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
67 years, 1916 to 2019
A day with at least 85.7 mm (3.4 in) of rain is expected about once in 2 years. A day with at least 322.4 mm (12.7 in) of rain is expected about once in 100 years.

Longer than the 67 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, 67 years of values from 1916 to 2019.
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: 392.7 mm (15.5 in) in 1994; 327.7 mm (12.9 in) in 2016; 202.2 mm (8.0 in) in 1970.
Station Changes
1 suspected
One change was suspected in the annual mean temperature of Washington Sp, at 1993. Each is measured against neighbouring stations.
Relative to 5 neighbouring stations, the station's annual mean temperature from 1993 ran 0.2 C (0.4 F) lower than in the years before (possible 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.
Climate Twins
2002 to 2016 against 1961 to 1990
Over 2002 to 2016, Washington Sp had a mean temperature of 20.1 C (68.2 F) and 1,069.4 mm (42.1 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Pierce 1 E (United States, 121 km away), Thompsons 3 WSW (United States, 107 km away) and Flatonia 4SE (United States, 116 km away).
Climate twins of Washington Sp: stations whose 1961 to 1990 climate is closest to its 2002 to 2016 climate
Twins are stations, not cities. A twin is one of the three stations at least 100 km away whose earlier climate is closest to this station's recent one, so a close match does not mean the two places look alike in other ways. A station move or a gap in a record can change that station's averages. The list describes past climate; it is not a forecast and does not say what caused any change. How twins are found, and a search for any station.
