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

43 years with a frost

Across 43 years with a frost, the median last spring frost at Salt Springs Pwr House falls on 29 April and the median first autumn frost on 11 November, which leaves a median of 195 days between them.

Fitted over all years, the growing season changes by -1.1 days per decade at this station.

Frost dates and growing season at Salt Springs Pwr House
Measure	Median, all years	Earliest period	Recent period (1957 to 1994)	Recent against earliest	Fitted trend
Last spring frost	29 April	n/a	3 May	n/a	+1.1 days per decade
First autumn frost	11 November	n/a	12 November	n/a	0.0 days per decade
Growing days	195 days	n/a	194 days	n/a	-1.1 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

48 years, 1944 to 1994

A day with at least 77.0 mm (3.0 in) of rain is expected about once in 2 years. A day with at least 165.7 mm (6.5 in) of rain is expected about once in 100 years.

Rainfall return levels at Salt Springs Pwr House: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	77.0 mm (3.0 in)
5 years	99.7 mm (3.9 in)
10 years	115.2 mm (4.5 in)
25 years	135.2 mm (5.3 in)
50 years	150.3 mm (5.9 in)	Longer than the 48 years of record
100 years	165.7 mm (6.5 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 1944 to 1994.

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: 157.0 mm (6.2 in) in 1955; 151.6 mm (6.0 in) in 1986; 136.9 mm (5.4 in) in 1963.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Salt Springs Pwr House, at 1976. Each is measured against neighbouring stations.

Year	Shift (C)	Shift (F)	Strength	Neighbours
1976	+0.4	+0.8	possible	5

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.
