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 at Vernon Coldstream Ranch
Measure	Median, all years	Earliest period (1902 to 1932)	Recent period (1953 to 1983)	Recent against earliest	Fitted trend
Last spring frost	5 May	5 May	8 May	3 days later	-0.4 days per decade
First autumn frost	5 October	3 October	8 October	5 days later	+1.0 days per decade
Growing days	153 days	148 days	154 days	6 days more	+1.4 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.

5 years	28.9 mm (1.1 in)
10 years	33.4 mm (1.3 in)
25 years	39.3 mm (1.5 in)
50 years	43.9 mm (1.7 in)
100 years	48.5 mm (1.9 in)	Longer than the 80 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, 80 years of values from 1903 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: 55.9 mm (2.2 in) in 1956; 49.5 mm (1.9 in) in 1924; 39.9 mm (1.6 in) in 1928.
