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

114 years with a frost

Across 114 years with a frost, the median last spring frost at Montrose #2 falls on 10 May and the median first autumn frost on 6 October, which leaves a median of 152 days between them.

In 1990 to 2024 the median growing season was 158 days. That is 21 days more than in 1905 to 1935.

Fitted over all years, the growing season changes by +2.4 days per decade at this station.

Growing days152 days137 days158 days21 days more+2.4 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

116 years, 1896 to 2016

A day with at least 20.8 mm (0.8 in) of rain is expected about once in 2 years. A day with at least 43.0 mm (1.7 in) of rain is expected about once in 100 years.

25 years35.8 mm (1.4 in)
50 years39.4 mm (1.6 in)
100 years43.0 mm (1.7 in)

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 116 years of values from 1896 to 2016.

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: 43.2 mm (1.7 in) in 1963; 38.9 mm (1.5 in) in 1986; 38.1 mm (1.5 in) in 1896.

Possible change at the station (a move, a new instrument or a new site); the record is kept as measured. A "likely" change has a larger test statistic than a "possible" one. Neither says why the station differs from its neighbours. How changes are found, and the largest ones.
