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

36 years with a frost

Across 36 years with a frost, the median last spring frost at Ceres Aero falls on 18 August and the median first autumn frost on 19 June, which leaves a median of 308 days between them.

Fitted over all years, the growing season changes by -2.0 days per decade at this station.

Frost dates and growing season at Ceres Aero
Measure	Median, all years	Earliest period	Recent period (1968 to 2003)	Recent against earliest	Fitted trend
Last spring frost	18 August	n/a	22 August	n/a	+5.2 days per decade
First autumn frost	19 June	n/a	19 June	n/a	+3.0 days per decade
Growing days	308 days	n/a	302 days	n/a	-2.0 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.
