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

46 years with a frost

Across 46 years with a frost, the median last spring frost at Barrage A Lac Kempt falls on 18 June and the median first autumn frost on 21 August, which leaves a median of 66 days between them.

Fitted over all years, the growing season changes by +12.8 days per decade at this station.

First autumn frost21 Augustn/a6 Septembern/a+9.8 days per decade
Growing days66 daysn/a81 daysn/a+12.8 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

48 years, 1922 to 1969

A day with at least 37.9 mm (1.5 in) of rain is expected about once in 2 years. A day with at least 89.5 mm (3.5 in) of rain is expected about once in 100 years.

50 years80.8 mm (3.2 in)Longer than the 48 years of record
100 years89.5 mm (3.5 in)Longer than the 48 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, 48 years of values from 1922 to 1969.

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: 87.6 mm (3.4 in) in 1927; 69.1 mm (2.7 in) in 1924; 68.1 mm (2.7 in) in 1958.

Station Changes

2 suspected

2 changes were suspected in the annual mean temperature of Barrage A Lac Kempt, at 1939 and 1956. Each is measured against neighbouring stations.

  • Relative to 5 neighbouring stations, the station's annual mean temperature from 1939 ran 1.4 C (2.5 F) higher than in the years before (likely change).
  • Relative to 5 neighbouring stations, the station's annual mean temperature from 1956 ran 0.5 C (0.8 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.
