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

67 years with a frost

Across 67 years with a frost, the median last spring frost at Dyer 5S falls on 21 May and the median first autumn frost on 25 September, which leaves a median of 130 days between them.

In 1983 to 2017 the median growing season was 146 days. That is 21 days more than in 1904 to 1975.

Fitted over all years, the growing season changes by +4.1 days per decade at this station.

Frost dates and growing season at Dyer 5S
Measure	Median, all years	Earliest period (1904 to 1975)	Recent period (1983 to 2017)	Recent against earliest	Fitted trend
Last spring frost	21 May	25 May	13 May	12 days earlier	-1.8 days per decade
First autumn frost	25 September	22 September	1 October	9 days later	+2.3 days per decade
Growing days	130 days	125 days	146 days	21 days more	+4.1 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

75 years, 1904 to 2017

A day with at least 21.2 mm (0.8 in) of rain is expected about once in 2 years. A day with at least 76.7 mm (3.0 in) of rain is expected about once in 100 years.

Rainfall return levels at Dyer 5S: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	21.2 mm (0.8 in)
5 years	31.9 mm (1.3 in)
10 years	40.4 mm (1.6 in)
25 years	53.1 mm (2.1 in)
50 years	64.1 mm (2.5 in)
100 years	76.7 mm (3.0 in)	Longer than the 75 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, 75 years of values from 1904 to 2017.

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: 78.0 mm (3.1 in) in 2015; 76.2 mm (3.0 in) in 2008; 52.1 mm (2.1 in) in 1983.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Dyer 5S, at 2002. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 2002 ran 0.4 C (0.6 F) lower than in the years before (likely change).

Suspected changes in the annual mean temperature at Dyer 5S, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
2002	-0.3	-0.6	likely	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.

Climate Twins

2003 to 2017 against 1961 to 1990

Over 2003 to 2017, Dyer 5S had a mean temperature of 11.5 C (52.6 F) and 131.6 mm (5.2 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Bruneau (United States, 616 km away), Fruitland (United States, 860 km away) and Wapato (United States, 1,002 km away).

Climate twins of Dyer 5S: stations whose 1961 to 1990 climate is closest to its 2003 to 2017 climate
Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Bruneau	United States	616 km (383 mi)	11.3 C (52.4 F)	184.0 mm (7.2 in)	0.53
Fruitland	United States	860 km (534 mi)	11.2 C (52.2 F)	211.2 mm (8.3 in)	0.67
Wapato	United States	1,002 km (623 mi)	11.5 C (52.8 F)	186.6 mm (7.3 in)	0.72

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.
