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

39 years, 1878 to 1917

A day with at least 21.5 mm (0.8 in) of rain is expected about once in 2 years. A day with at least 44.7 mm (1.8 in) of rain is expected about once in 100 years.

Rainfall return levels at Nicola Lake: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	21.5 mm (0.8 in)
5 years	28.3 mm (1.1 in)
10 years	32.5 mm (1.3 in)
25 years	37.6 mm (1.5 in)
50 years	41.3 mm (1.6 in)	Longer than the 39 years of record
100 years	44.7 mm (1.8 in)	Longer than the 39 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, 39 years of values from 1878 to 1917.

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: 44.5 mm (1.8 in) in 1914; 41.1 mm (1.6 in) in 1888; 34.3 mm (1.4 in) in 1897.
