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

69 years with a frost

Across 69 years with a frost, the median last spring frost at St Albans falls on 1 June and the median first autumn frost on 10 September, which leaves a median of 104 days between them.

In 1928 to 1959 the median growing season was 107 days. That is 7 days more than in 1886 to 1918.

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

Frost dates and growing season at St Albans
Measure	Median, all years	Earliest period (1886 to 1918)	Recent period (1928 to 1959)	Recent against earliest	Fitted trend
Last spring frost	1 June	1 June	1 June	no change	+0.1 days per decade
First autumn frost	10 September	4 September	16 September	12 days later	+2.1 days per decade
Growing days	104 days	100 days	107 days	7 days more	+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.

Rainfall Return Levels

75 years, 1885 to 1959

A day with at least 40.4 mm (1.6 in) of rain is expected about once in 2 years. A day with at least 91.8 mm (3.6 in) of rain is expected about once in 100 years.

Rainfall return levels at St Albans: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	40.4 mm (1.6 in)
5 years	54.4 mm (2.1 in)
10 years	63.5 mm (2.5 in)
25 years	75.0 mm (3.0 in)
50 years	83.5 mm (3.3 in)
100 years	91.8 mm (3.6 in)	Longer than the 75 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, 75 years of values from 1885 to 1959.

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: 89.4 mm (3.5 in) in 1955; 74.2 mm (2.9 in) in 1907; 74.2 mm (2.9 in) in 1926.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of St Albans, at 1935. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1935 ran 0.2 C (0.3 F) lower than in the years before (likely change).

Suspected changes in the annual mean temperature at St Albans, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1935	-0.2	-0.3	likely	5

Possible change at the station (a move, a new instrument or a new site); the record is kept as measured. A "likely" change has a larger test statistic than a "possible" one. Neither says why the station differs from its neighbours. How changes are found, and the largest ones.
