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

64 years with a frost

Across 64 years with a frost, the median last spring frost at Hamlin falls on 30 April and the median first autumn frost on 11 October, which leaves a median of 164 days between them.

In 1980 to 2013 the median growing season was 169 days. That is 11 days more than in 1944 to 1975.

Fitted over all years, the growing season changes by +2.8 days per decade at this station.

Frost dates and growing season at Hamlin
Measure	Median, all years	Earliest period (1944 to 1975)	Recent period (1980 to 2013)	Recent against earliest	Fitted trend
Last spring frost	30 April	30 April	30 April	no change	-0.9 days per decade
First autumn frost	11 October	7 October	15 October	8 days later	+1.9 days per decade
Growing days	164 days	158 days	169 days	11 days more	+2.8 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

70 years, 1944 to 2013

A day with at least 55.2 mm (2.2 in) of rain is expected about once in 2 years. A day with at least 109.5 mm (4.3 in) of rain is expected about once in 100 years.

Rainfall return levels at Hamlin: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	55.2 mm (2.2 in)
5 years	67.7 mm (2.7 in)
10 years	76.8 mm (3.0 in)
25 years	89.1 mm (3.5 in)
50 years	99.0 mm (3.9 in)
100 years	109.5 mm (4.3 in)	Longer than the 70 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, 70 years of values from 1944 to 2013.

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: 103.9 mm (4.1 in) in 1978; 93.7 mm (3.7 in) in 2010; 90.4 mm (3.6 in) in 2003.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Hamlin, at 1956. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1956 ran 0.5 C (0.8 F) higher than in the years before (possible change).

Suspected changes in the annual mean temperature at Hamlin, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1956	+0.5	+0.8	possible	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.
