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

87 years with a frost

Across 87 years with a frost, the median last spring frost at Banff falls on 13 June and the median first autumn frost on 23 August, which leaves a median of 66 days between them.

In 1954 to 1983 the median growing season was 93 days. That is 36 days more than in 1890 to 1923.

Fitted over all years, the growing season changes by +6.1 days per decade at this station.

First autumn frost23 August12 August3 September22 days later+4.2 days per decade
Growing days66 days57 days93 days36 days more+6.1 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

89 years, 1890 to 1983

A day with at least 30.7 mm (1.2 in) of rain is expected about once in 2 years. A day with at least 61.3 mm (2.4 in) of rain is expected about once in 100 years.

100 years61.3 mm (2.4 in)Longer than the 89 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, 89 years of values from 1890 to 1983.

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: 53.6 mm (2.1 in) in 1973; 52.8 mm (2.1 in) in 1907; 50.3 mm (2.0 in) in 1902.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Banff, at 1965. Each is measured against neighbouring stations.

  • Relative to 5 neighbouring stations, the station's annual mean temperature from 1965 ran 0.4 C (0.7 F) higher than in the years before (likely 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.
