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

21 years with a frost

Across 21 years with a frost, the median last spring frost at Lookout Peak falls on 13 June and the median first autumn frost on 20 September, which leaves a median of 104 days between them.

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

37 years, 1989 to 2025

A day with at least 53.6 mm (2.1 in) of rain is expected about once in 2 years. A day with at least 125.5 mm (4.9 in) of rain is expected about once in 100 years.

Rainfall return levels at Lookout Peak: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	53.6 mm (2.1 in)
5 years	67.2 mm (2.6 in)
10 years	78.1 mm (3.1 in)
25 years	94.6 mm (3.7 in)
50 years	109.0 mm (4.3 in)	Longer than the 37 years of record
100 years	125.5 mm (4.9 in)	Longer than the 37 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, 37 years of values from 1989 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: 114.3 mm (4.5 in) in 2023; 111.8 mm (4.4 in) in 2010; 88.9 mm (3.5 in) in 2012.
