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

47 years with a frost

Across 47 years with a frost, the median last spring frost at Cody 12SE falls on 24 May and the median first autumn frost on 17 September, which leaves a median of 118 days between them.

Fitted over all years, the growing season changes by +0.8 days per decade at this station.

Frost dates and growing season at Cody 12SE
Measure	Median, all years	Earliest period	Recent period (1986 to 2025)	Recent against earliest	Fitted trend
Last spring frost	24 May	n/a	23 May	n/a	-0.1 days per decade
First autumn frost	17 September	n/a	18 September	n/a	+0.8 days per decade
Growing days	118 days	n/a	121 days	n/a	+0.8 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

54 years, 1950 to 2025

A day with at least 29.0 mm (1.1 in) of rain is expected about once in 2 years. A day with at least 80.7 mm (3.2 in) of rain is expected about once in 100 years.

Rainfall return levels at Cody 12SE: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	29.0 mm (1.1 in)
5 years	41.1 mm (1.6 in)
10 years	49.8 mm (2.0 in)
25 years	61.6 mm (2.4 in)
50 years	70.9 mm (2.8 in)
100 years	80.7 mm (3.2 in)	Longer than the 54 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, 54 years of values from 1950 to 2025.

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: 66.8 mm (2.6 in) in 1968; 64.5 mm (2.5 in) in 2001; 63.5 mm (2.5 in) in 1950.

Station Changes

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

Climate Twins

2008 to 2025 against 1961 to 1990

Over 2008 to 2025, Cody 12SE had a mean temperature of 6.8 C (44.2 F) and 262.4 mm (10.3 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Bates Creek #2 (United States, 286 km away), Flaming Gorge (United States, 390 km away) and Billy Creek (United States, 176 km away).

Climate twins of Cody 12SE: stations whose 1961 to 1990 climate is closest to its 2008 to 2025 climate
Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Bates Creek #2	United States	286 km (178 mi)	7.2 C (44.9 F)	315.9 mm (12.4 in)	0.91
Flaming Gorge	United States	390 km (242 mi)	6.7 C (44.0 F)	304.6 mm (12.0 in)	0.95
Billy Creek	United States	176 km (109 mi)	7.0 C (44.5 F)	311.0 mm (12.2 in)	0.95

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.
