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

70 years with a frost

Across 70 years with a frost, the median last spring frost at Martin U of T Branch Exp STN falls on 8 April and the median first autumn frost on 26 October, which leaves a median of 202 days between them.

In 1983 to 2021 the median growing season was 200 days. The two periods have the same number of growing days.

Fitted over all years, the growing season changes by +0.7 days per decade at this station.

Growing days202 days200 days200 daysno change+0.7 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

79 years, 1937 to 2021

A day with at least 78.2 mm (3.1 in) of rain is expected about once in 2 years. A day with at least 196.0 mm (7.7 in) of rain is expected about once in 100 years.

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 79 years of values from 1937 to 2021.

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: 233.7 mm (9.2 in) in 1975; 184.2 mm (7.3 in) in 1957; 153.4 mm (6.0 in) in 1952.

Climate Twins

2002 to 2021 against 1961 to 1990

Over 2002 to 2021, Martin U of T Branch Exp STN had a mean temperature of 15.2 C (59.3 F) and 1,447.2 mm (57.0 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Covington 3 SW (United States, 117 km away), Ripley (United States, 179 km away) and Bolivar Wtr Wks (United States, 121 km away).

Twins are stations, not cities. A twin is one of the three stations at least 100 km away whose earlier climate is closest to this station's recent one, so a close match does not mean the two places look alike in other ways. A station move or a gap in a record can change that station's averages. The list describes past climate; it is not a forecast and does not say what caused any change. How twins are found, and a search for any station.
