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

32 years, 1965 to 1999

A day with at least 32.6 mm (1.3 in) of rain is expected about once in 2 years. A day with at least 85.6 mm (3.4 in) of rain is expected about once in 100 years.

Rainfall return levels at Vasterplana: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	32.6 mm (1.3 in)
5 years	43.9 mm (1.7 in)
10 years	52.4 mm (2.1 in)
25 years	64.5 mm (2.5 in)
50 years	74.6 mm (2.9 in)	Longer than the 32 years of record
100 years	85.6 mm (3.4 in)	Longer than the 32 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, 32 years of values from 1965 to 1999.

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: 68.2 mm (2.7 in) in 1999; 65.3 mm (2.6 in) in 1979; 63.3 mm (2.5 in) in 1970.
