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

65 years with a frost

Across 65 years with a frost, the median last spring frost at Celo 2 S falls on 9 May and the median first autumn frost on 5 October, which leaves a median of 146 days between them.

In 1987 to 2025 the median growing season was 165 days. That is 28 days more than in 1951 to 1981.

Fitted over all years, the growing season changes by +7.6 days per decade at this station.

Frost dates and growing season at Celo 2 S
Measure	Median, all years	Earliest period (1951 to 1981)	Recent period (1987 to 2025)	Recent against earliest	Fitted trend
Last spring frost	9 May	17 May	27 April	20 days earlier	-4.7 days per decade
First autumn frost	5 October	2 October	10 October	8 days later	+2.9 days per decade
Growing days	146 days	137 days	165 days	28 days more	+7.6 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

65 years, 1949 to 2025

A day with at least 90.0 mm (3.5 in) of rain is expected about once in 2 years. A day with at least 278.3 mm (11.0 in) of rain is expected about once in 100 years.

Rainfall return levels at Celo 2 S: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	90.0 mm (3.5 in)
5 years	125.5 mm (4.9 in)
10 years	154.0 mm (6.1 in)
25 years	197.1 mm (7.8 in)
50 years	234.9 mm (9.2 in)
100 years	278.3 mm (11.0 in)	Longer than the 65 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, 65 years of values from 1949 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: 302.0 mm (11.9 in) in 2024; 274.3 mm (10.8 in) in 2010; 199.6 mm (7.9 in) in 1998.

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

Climate Twins

2002 to 2025 against 1961 to 1990

Over 2002 to 2025, Celo 2 S had a mean temperature of 12.0 C (53.7 F) and 1,649.3 mm (64.9 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Lugano (Switzerland, 7,318 km away), Andrews (United States, 165 km away) and Coweeta Exp STN (United States, 141 km away).

Climate twins of Celo 2 S: stations whose 1961 to 1990 climate is closest to its 2002 to 2025 climate
Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Lugano	Switzerland	7,318 km (4,547 mi)	12.2 C (54.0 F)	1,607.7 mm (63.3 in)	0.79
Andrews	United States	165 km (103 mi)	12.6 C (54.6 F)	1,558.3 mm (61.4 in)	0.83
Coweeta Exp STN	United States	141 km (88 mi)	12.3 C (54.2 F)	1,824.2 mm (71.8 in)	0.85

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.
