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 Bancroft
Measure	Median, all years	Earliest period	Recent period (1919 to 1982)	Recent against earliest	Fitted trend
Last spring frost	30 May	n/a	30 May	n/a	-1.0 days per decade
First autumn frost	11 September	n/a	17 September	n/a	+2.1 days per decade
Growing days	104 days	n/a	106 days	n/a	+3.1 days per decade

50 years	77.6 mm (3.1 in)
100 years	82.6 mm (3.3 in)	Longer than the 60 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, 60 years of values from 1883 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: 83.2 mm (3.3 in) in 1981; 76.2 mm (3.0 in) in 1927; 69.1 mm (2.7 in) in 1926.
