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

23 years with a frost

Across 23 years with a frost, the median last spring frost at Horse Ridge falls on 13 June and the median first autumn frost on 16 September, which leaves a median of 96 days between them.

Frost dates and growing season at Horse Ridge
Measure	Median, all years	Earliest period	Recent period (2003 to 2025)	Recent against earliest	Fitted trend
Last spring frost	13 June	n/a	13 June	n/a	n/a
First autumn frost	16 September	n/a	16 September	n/a	n/a
Growing days	96 days	n/a	96 days	n/a	n/a

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

47 years, 1979 to 2025

A day with at least 38.4 mm (1.5 in) of rain is expected about once in 2 years. A day with at least 89.7 mm (3.5 in) of rain is expected about once in 100 years.

Rainfall return levels at Horse Ridge: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	38.4 mm (1.5 in)
5 years	48.5 mm (1.9 in)
10 years	56.5 mm (2.2 in)
25 years	68.2 mm (2.7 in)
50 years	78.3 mm (3.1 in)	Longer than the 47 years of record
100 years	89.7 mm (3.5 in)	Longer than the 47 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, 47 years of values from 1979 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: 83.8 mm (3.3 in) in 2022; 73.7 mm (2.9 in) in 1986; 61.0 mm (2.4 in) in 1983.
