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

85 years with a frost

Across 85 years with a frost, the median last spring frost at Buckeye falls on 4 March and the median first autumn frost on 20 November, which leaves a median of 263 days between them.

In 1966 to 2002 the median growing season was 290 days. That is 41 days more than in 1894 to 1932.

Fitted over all years, the growing season changes by +5.4 days per decade at this station.

Frost dates and growing season at Buckeye
Measure	Median, all years	Earliest period (1894 to 1932)	Recent period (1966 to 2002)	Recent against earliest	Fitted trend
Last spring frost	4 March	20 March	16 February	32 days earlier	-4.2 days per decade
First autumn frost	20 November	19 November	28 November	9 days later	+1.2 days per decade
Growing days	263 days	249 days	290 days	41 days more	+5.4 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

97 years, 1894 to 2002

A day with at least 29.3 mm (1.2 in) of rain is expected about once in 2 years. A day with at least 94.2 mm (3.7 in) of rain is expected about once in 100 years.

Rainfall return levels at Buckeye: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	29.3 mm (1.2 in)
5 years	41.9 mm (1.6 in)
10 years	51.9 mm (2.0 in)
25 years	66.7 mm (2.6 in)
50 years	79.6 mm (3.1 in)
100 years	94.2 mm (3.7 in)	Longer than the 97 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, 97 years of values from 1894 to 2002.

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: 124.5 mm (4.9 in) in 1894; 83.6 mm (3.3 in) in 1916; 72.6 mm (2.9 in) in 1907.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Buckeye, at 1989. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1989 ran 0.6 C (1.1 F) lower than in the years before (likely change).

Suspected changes in the annual mean temperature at Buckeye, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1989	-0.6	-1.1	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.
