2 years	65.8 mm (2.6 in)
5 years	90.5 mm (3.6 in)
10 years	108.0 mm (4.3 in)
25 years	131.5 mm (5.2 in)
50 years	150.1 mm (5.9 in)
100 years	169.5 mm (6.7 in)	Longer than the 94 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, 94 years of values from 1911 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: 208.8 mm (8.2 in) in 1978; 151.1 mm (5.9 in) in 1941; 149.4 mm (5.9 in) in 1990.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Stamford 1, at 2003. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 2003 ran 0.3 C (0.6 F) lower than in the years before (likely change).

Suspected changes in the annual mean temperature at Stamford 1, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
2003	-0.3	-0.6	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.
