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

105 years with a frost

Across 105 years with a frost, the median last spring frost at Cambridge falls on 18 May and the median first autumn frost on 19 September, which leaves a median of 122 days between them.

In 1991 to 2021 the median growing season was 132 days. That is 11 days more than in 1895 to 1941.

Fitted over all years, the growing season changes by +1.6 days per decade at this station.

Frost dates and growing season at Cambridge
Measure	Median, all years	Earliest period (1895 to 1941)	Recent period (1991 to 2021)	Recent against earliest	Fitted trend
Last spring frost	18 May	19 May	14 May	5 days earlier	-0.5 days per decade
First autumn frost	19 September	16 September	27 September	11 days later	+1.1 days per decade
Growing days	122 days	121 days	132 days	11 days more	+1.6 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

109 years, 1894 to 2021

A day with at least 29.2 mm (1.1 in) of rain is expected about once in 2 years. A day with at least 65.5 mm (2.6 in) of rain is expected about once in 100 years.

Rainfall return levels at Cambridge: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	29.2 mm (1.1 in)
5 years	37.1 mm (1.5 in)
10 years	43.1 mm (1.7 in)
25 years	51.3 mm (2.0 in)
50 years	58.1 mm (2.3 in)
100 years	65.5 mm (2.6 in)

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 109 years of values from 1894 to 2021.

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: 66.0 mm (2.6 in) in 1956; 58.4 mm (2.3 in) in 1952; 54.9 mm (2.2 in) in 1954.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Cambridge, at 1970. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1970 ran 0.5 C (0.8 F) higher than in the years before (likely change).

Suspected changes in the annual mean temperature at Cambridge, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1970	+0.5	+0.8	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.

Climate Twins

2006 to 2021 against 1961 to 1990

Over 2006 to 2021, Cambridge had a mean temperature of 9.5 C (49.0 F) and 509.1 mm (20.0 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Enders Lake (United States, 1,324 km away), Wallace 2W (United States, 1,328 km away) and Corinne (United States, 501 km away).

Climate twins of Cambridge: stations whose 1961 to 1990 climate is closest to its 2006 to 2021 climate
Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Enders Lake	United States	1,324 km (823 mi)	9.6 C (49.3 F)	478.8 mm (18.9 in)	0.74
Wallace 2W	United States	1,328 km (825 mi)	9.3 C (48.7 F)	432.6 mm (17.0 in)	0.79
Corinne	United States	501 km (311 mi)	9.2 C (48.6 F)	446.1 mm (17.6 in)	0.81

Twins are stations, not cities. A twin is one of the three stations at least 100 km away whose earlier climate is closest to this station's recent one, so a close match does not mean the two places look alike in other ways. A station move or a gap in a record can change that station's averages. The list describes past climate; it is not a forecast and does not say what caused any change. How twins are found, and a search for any station.
