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

54 years with a frost

Across 54 years with a frost, the median last spring frost at Picabo falls on 14 June and the median first autumn frost on 6 September, which leaves a median of 88 days between them.

Fitted over all years, the growing season changes by +3.4 days per decade at this station.

Frost dates and growing season at Picabo
Measure	Median, all years	Earliest period	Recent period (1987 to 2022)	Recent against earliest	Fitted trend
Last spring frost	14 June	n/a	14 June	n/a	+0.6 days per decade
First autumn frost	6 September	n/a	9 September	n/a	+4.0 days per decade
Growing days	88 days	n/a	91 days	n/a	+3.4 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

62 years, 1960 to 2022

A day with at least 24.9 mm (1.0 in) of rain is expected about once in 2 years. A day with at least 75.4 mm (3.0 in) of rain is expected about once in 100 years.

Rainfall return levels at Picabo: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	24.9 mm (1.0 in)
5 years	34.4 mm (1.4 in)
10 years	42.1 mm (1.7 in)
25 years	53.6 mm (2.1 in)
50 years	63.8 mm (2.5 in)
100 years	75.4 mm (3.0 in)	Longer than the 62 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, 62 years of values from 1960 to 2022.

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: 83.8 mm (3.3 in) in 1995; 62.2 mm (2.4 in) in 1964; 50.8 mm (2.0 in) in 1963.

Station Changes

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

Climate Twins

2003 to 2022 against 1961 to 1990

Over 2003 to 2022, Picabo had a mean temperature of 6.1 C (43.0 F) and 312.7 mm (12.3 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Grace (United States, 205 km away), Sonnette 7 SW (United States, 686 km away) and Altamont (United States, 452 km away).

Climate twins of Picabo: stations whose 1961 to 1990 climate is closest to its 2003 to 2022 climate
Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Grace	United States	205 km (127 mi)	6.1 C (43.0 F)	390.6 mm (15.4 in)	0.73
Sonnette 7 SW	United States	686 km (426 mi)	6.3 C (43.3 F)	389.4 mm (15.3 in)	0.74
Altamont	United States	452 km (281 mi)	6.3 C (43.4 F)	232.0 mm (9.1 in)	0.74

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.
