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

54 years with a frost

Across 54 years with a frost, the median last spring frost at Florence falls on 6 April and the median first autumn frost on 29 October, which leaves a median of 206 days between them.

Fitted over all years, the growing season changes by -1.2 days per decade at this station.

Frost dates and growing season at Florence
Measure	Median, all years	Earliest period	Recent period (1925 to 1976)	Recent against earliest	Fitted trend
Last spring frost	6 April	n/a	6 April	n/a	+0.6 days per decade
First autumn frost	29 October	n/a	27 October	n/a	-0.5 days per decade
Growing days	206 days	n/a	209 days	n/a	-1.2 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

59 years, 1895 to 1976

A day with at least 77.2 mm (3.0 in) of rain is expected about once in 2 years. A day with at least 161.0 mm (6.3 in) of rain is expected about once in 100 years.

Rainfall return levels at Florence: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	77.2 mm (3.0 in)
5 years	100.1 mm (3.9 in)
10 years	115.1 mm (4.5 in)
25 years	133.8 mm (5.3 in)
50 years	147.5 mm (5.8 in)
100 years	161.0 mm (6.3 in)	Longer than the 59 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, 59 years of values from 1895 to 1976.

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: 143.3 mm (5.6 in) in 1916; 132.1 mm (5.2 in) in 1920; 130.8 mm (5.1 in) in 1897.
