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

97 years with a frost

Across 97 years with a frost, the median last spring frost at Saint Bernard falls on 10 April and the median first autumn frost on 25 October, which leaves a median of 198 days between them.

In 1983 to 2023 the median growing season was 197 days. That is 3 days more than in 1908 to 1938.

Fitted over all years, the growing season changes by +0.9 days per decade at this station.

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

104 years, 1908 to 2025

A day with at least 85.0 mm (3.3 in) of rain is expected about once in 2 years. A day with at least 174.1 mm (6.9 in) of rain is expected about once in 100 years.

25 years144.8 mm (5.7 in)
50 years159.5 mm (6.3 in)
100 years174.1 mm (6.9 in)

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 104 years of values from 1908 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: 229.4 mm (9.0 in) in 1980; 156.2 mm (6.1 in) in 1932; 142.7 mm (5.6 in) in 1973.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Saint Bernard, at 1967. Each is measured against neighbouring stations.

  • Relative to 5 neighbouring stations, the station's annual mean temperature from 1967 ran 0.3 C (0.5 F) lower than in the years before (possible change).

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.

Climate Twins

1998 to 2023 against 1961 to 1990

Over 1998 to 2023, Saint Bernard had a mean temperature of 16.3 C (61.4 F) and 1,535.0 mm (60.4 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Fulton 3 W (United States, 152 km away), Clanton (United States, 152 km away) and Kosciusko (United States, 285 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.
