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

72 years with a frost

Across 72 years with a frost, the median last spring frost at Marlow 1 WSW falls on 3 April and the median first autumn frost on 2 November, which leaves a median of 216 days between them.

In 1947 to 1976 the median growing season was 212 days. That is 6 days fewer than in 1901 to 1933.

Fitted over all years, the growing season changes by -0.8 days per decade at this station.

First autumn frost2 November2 November2 Novemberno change-0.3 days per decade
Growing days216 days218 days212 days6 days fewer-0.8 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

125 years, 1901 to 2025

A day with at least 78.8 mm (3.1 in) of rain is expected about once in 2 years. A day with at least 191.5 mm (7.5 in) of rain is expected about once in 100 years.

2 years78.8 mm (3.1 in)

25 years150.0 mm (5.9 in)
50 years170.3 mm (6.7 in)
100 years191.5 mm (7.5 in)

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 125 years of values from 1901 to 2025.

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: 238.3 mm (9.4 in) in 1987; 195.1 mm (7.7 in) in 1992; 179.3 mm (7.1 in) in 1983.
