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

26 years with a frost

Across 26 years with a frost, the median last spring frost at Tohatchi 1 ESE falls on 3 May and the median first autumn frost on 21 October, which leaves a median of 168 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 Tohatchi 1 ESE
Measure	Median, all years	Earliest period	Recent period (1918 to 1976)	Recent against earliest	Fitted trend
Last spring frost	3 May	n/a	3 May	n/a	-0.8 days per decade
First autumn frost	21 October	n/a	21 October	n/a	-1.9 days per decade
Growing days	168 days	n/a	168 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

43 years, 1915 to 1977

A day with at least 23.3 mm (0.9 in) of rain is expected about once in 2 years. A day with at least 50.0 mm (2.0 in) of rain is expected about once in 100 years.

Rainfall return levels at Tohatchi 1 ESE: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	23.3 mm (0.9 in)
5 years	31.0 mm (1.2 in)
10 years	35.9 mm (1.4 in)
25 years	41.8 mm (1.6 in)
50 years	46.0 mm (1.8 in)	Longer than the 43 years of record
100 years	50.0 mm (2.0 in)	Longer than the 43 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, 43 years of values from 1915 to 1977.

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: 48.3 mm (1.9 in) in 1977; 45.7 mm (1.8 in) in 1927; 37.1 mm (1.5 in) in 1965.
