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

61 years with a frost

Across 61 years with a frost, the median last spring frost at Martinsdale 3 NNW falls on 9 June and the median first autumn frost on 2 September, which leaves a median of 84 days between them.

In 1970 to 2011 the median growing season was 87 days. That is 1 day more than in 1893 to 1968.

Fitted over all years, the growing season changes by +0.7 days per decade at this station.

Frost dates and growing season at Martinsdale 3 NNW
Measure	Median, all years	Earliest period (1893 to 1968)	Recent period (1970 to 2011)	Recent against earliest	Fitted trend
Last spring frost	9 June	7 June	8 June	1 day later	+0.4 days per decade
First autumn frost	2 September	31 August	2 September	2 days later	+1.2 days per decade
Growing days	84 days	86 days	87 days	1 day more	+0.7 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

68 years, 1893 to 2010

A day with at least 29.6 mm (1.2 in) of rain is expected about once in 2 years. A day with at least 70.7 mm (2.8 in) of rain is expected about once in 100 years.

Rainfall return levels at Martinsdale 3 NNW: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	29.6 mm (1.2 in)
5 years	40.4 mm (1.6 in)
10 years	47.6 mm (1.9 in)
25 years	56.8 mm (2.2 in)
50 years	63.8 mm (2.5 in)
100 years	70.7 mm (2.8 in)	Longer than the 68 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, 68 years of values from 1893 to 2010.

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: 81.3 mm (3.2 in) in 1900; 60.5 mm (2.4 in) in 1959; 56.6 mm (2.2 in) in 1979.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Martinsdale 3 NNW, at 1973. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1973 ran 0.4 C (0.7 F) lower than in the years before (likely change).

Year	Shift (C)	Shift (F)	Strength	Neighbours
1973	-0.4	-0.7	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.
