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

101 years with a frost

Across 101 years with a frost, the median last spring frost at Oregon falls on 18 April and the median first autumn frost on 19 October, which leaves a median of 184 days between them.

In 1968 to 2018 the median growing season was 185 days. That is 4 days more than in 1893 to 1924.

Fitted over all years, the growing season changes by 0.0 days per decade at this station.

Frost dates and growing season at Oregon
Measure	Median, all years	Earliest period (1893 to 1924)	Recent period (1968 to 2018)	Recent against earliest	Fitted trend
Last spring frost	18 April	19 April	16 April	3 days earlier	-0.1 days per decade
First autumn frost	19 October	20 October	19 October	1 day earlier	-0.1 days per decade
Growing days	184 days	181 days	185 days	4 days more	0.0 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

92 years, 1897 to 2018

A day with at least 70.0 mm (2.8 in) of rain is expected about once in 2 years. A day with at least 173.0 mm (6.8 in) of rain is expected about once in 100 years.

Rainfall return levels at Oregon: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	70.0 mm (2.8 in)
5 years	92.5 mm (3.6 in)
10 years	109.3 mm (4.3 in)
25 years	132.8 mm (5.2 in)
50 years	152.1 mm (6.0 in)
100 years	173.0 mm (6.8 in)	Longer than the 92 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, 92 years of values from 1897 to 2018.

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: 168.9 mm (6.6 in) in 1933; 157.5 mm (6.2 in) in 2000; 135.9 mm (5.4 in) in 1905.

Station Changes

No change in the annual mean temperature of this station was found against its neighbours.

Climate Twins

1998 to 2018 against 1961 to 1990

Over 1998 to 2018, Oregon had a mean temperature of 11.7 C (53.0 F) and 876.7 mm (34.5 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Keokuk L&D 19 (United States, 324 km away), Steffenville (United States, 278 km away) and Springfield Abraham Lincoln Ca (United States, 466 km away).

Climate twins of Oregon: stations whose 1961 to 1990 climate is closest to its 1998 to 2018 climate
Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Keokuk L&D 19	United States	324 km (201 mi)	11.7 C (53.0 F)	933.6 mm (36.8 in)	0.51
Steffenville	United States	278 km (173 mi)	11.4 C (52.6 F)	931.4 mm (36.7 in)	0.53
Springfield Abraham Lincoln Ca	United States	466 km (290 mi)	11.4 C (52.5 F)	896.4 mm (35.3 in)	0.56

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.
