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

59 years with a frost

Across 59 years with a frost, the median last spring frost at Ralston falls on 6 April and the median first autumn frost on 21 October, which leaves a median of 198 days between them.

Fitted over all years, the growing season changes by -0.1 days per decade at this station.

Frost dates and growing season at Ralston
Measure	Median, all years	Earliest period	Recent period (1989 to 2024)	Recent against earliest	Fitted trend
Last spring frost	6 April	n/a	8 April	n/a	+0.2 days per decade
First autumn frost	21 October	n/a	22 October	n/a	+0.2 days per decade
Growing days	198 days	n/a	199 days	n/a	-0.1 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

91 years, 1925 to 2023

A day with at least 72.0 mm (2.8 in) of rain is expected about once in 2 years. A day with at least 211.0 mm (8.3 in) of rain is expected about once in 100 years.

Rainfall return levels at Ralston: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	72.0 mm (2.8 in)
5 years	99.0 mm (3.9 in)
10 years	120.4 mm (4.7 in)
25 years	152.2 mm (6.0 in)
50 years	179.7 mm (7.1 in)
100 years	211.0 mm (8.3 in)	Longer than the 91 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, 91 years of values from 1925 to 2023.

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: 208.3 mm (8.2 in) in 2019; 196.9 mm (7.8 in) in 1986; 181.6 mm (7.1 in) in 1997.

Climate Twins

2006 to 2024 against 1961 to 1990

Over 2006 to 2024, Ralston had a mean temperature of 15.7 C (60.2 F) and 906.5 mm (35.7 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Oklahoma Cy Will Rogers World (United States, 146 km away), Enid (United States, 102 km away) and Meeker 5 W (United States, 113 km away).

Climate twins of Ralston: stations whose 1961 to 1990 climate is closest to its 2006 to 2024 climate
Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Oklahoma Cy Will Rogers World	United States	146 km (91 mi)	15.5 C (60.0 F)	847.5 mm (33.4 in)	0.50
Enid	United States	102 km (63 mi)	15.6 C (60.1 F)	826.7 mm (32.5 in)	0.58
Meeker 5 W	United States	113 km (70 mi)	15.8 C (60.5 F)	828.1 mm (32.6 in)	0.59

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.
