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 Hammond falls on 14 March and the median first autumn frost on 12 November, which leaves a median of 243 days between them.

In 1957 to 1986 the median growing season was 243 days. The two periods have the same number of growing days.

Fitted over all years, the growing season changes by -1.2 days per decade at this station.

Frost dates and growing season at Hammond
Measure	Median, all years	Earliest period (1897 to 1941)	Recent period (1957 to 1986)	Recent against earliest	Fitted trend
Last spring frost	14 March	15 March	17 March	2 days later	+1.0 days per decade
First autumn frost	12 November	13 November	12 November	1 day earlier	-0.2 days per decade
Growing days	243 days	243 days	243 days	no change	-1.2 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

94 years, 1896 to 2008

A day with at least 103.1 mm (4.1 in) of rain is expected about once in 2 years. A day with at least 268.9 mm (10.6 in) of rain is expected about once in 100 years.

Rainfall return levels at Hammond: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	103.1 mm (4.1 in)
5 years	142.6 mm (5.6 in)
10 years	170.5 mm (6.7 in)
25 years	208.2 mm (8.2 in)
50 years	237.9 mm (9.4 in)
100 years	268.9 mm (10.6 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 1896 to 2008.

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: 269.2 mm (10.6 in) in 2008; 241.0 mm (9.5 in) in 1937; 238.8 mm (9.4 in) in 1916.

Station Changes

2 suspected

2 changes were suspected in the annual mean temperature of Hammond, at 1958 and 1978. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1958 ran 0.5 C (1.0 F) lower than in the years before (likely change).
Relative to 5 neighbouring stations, the station's annual mean temperature from 1978 ran 0.2 C (0.4 F) lower than in the years before (likely change).

Suspected changes in the annual mean temperature at Hammond, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1958	-0.5	-1.0	likely	5
1978	-0.2	-0.4	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.
