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

71 years with a frost

Across 71 years with a frost, the median last spring frost at Reboly falls on 20 May and the median first autumn frost on 19 September, which leaves a median of 122 days between them.

In 1987 to 2025 the median growing season was 127 days. That is 12 days more than in 1938 to 1975.

Fitted over all years, the growing season changes by +2.5 days per decade at this station.

Frost dates and growing season at Reboly
Measure	Median, all years	Earliest period (1938 to 1975)	Recent period (1987 to 2025)	Recent against earliest	Fitted trend
Last spring frost	20 May	23 May	16 May	7 days earlier	-1.5 days per decade
First autumn frost	19 September	17 September	24 September	7 days later	+1.0 days per decade
Growing days	122 days	115 days	127 days	12 days more	+2.5 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

80 years, 1938 to 2025

A day with at least 25.7 mm (1.0 in) of rain is expected about once in 2 years. A day with at least 77.2 mm (3.0 in) of rain is expected about once in 100 years.

Rainfall return levels at Reboly: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	25.7 mm (1.0 in)
5 years	35.7 mm (1.4 in)
10 years	43.6 mm (1.7 in)
25 years	55.4 mm (2.2 in)
50 years	65.6 mm (2.6 in)
100 years	77.2 mm (3.0 in)	Longer than the 80 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, 80 years of values from 1938 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: 113.0 mm (4.4 in) in 2025; 64.3 mm (2.5 in) in 1998; 59.8 mm (2.4 in) in 2012.

Climate Twins

2005 to 2025 against 1961 to 1990

Over 2005 to 2025, Reboly had a mean temperature of 2.8 C (37.0 F) and 674.4 mm (26.6 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Sortavala (Russia, 234 km away), Joutsa Leivonmaki Savenaho (Finland, 322 km away) and Kuopio Inkilanmaki (Finland, 187 km away).

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.
