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

60 years with a frost

Across 60 years with a frost, the median last spring frost at Kuna falls on 16 May and the median first autumn frost on 23 September, which leaves a median of 132 days between them.

In 1962 to 1995 the median growing season was 126 days. That is 14 days fewer than in 1926 to 1961.

Fitted over all years, the growing season changes by -5.7 days per decade at this station.

Frost dates and growing season at Kuna
Measure	Median, all years	Earliest period (1926 to 1961)	Recent period (1962 to 1995)	Recent against earliest	Fitted trend
Last spring frost	16 May	10 May	22 May	12 days later	+2.5 days per decade
First autumn frost	23 September	24 September	23 September	1 day earlier	-3.3 days per decade
Growing days	132 days	140 days	126 days	14 days fewer	-5.7 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

60 years, 1926 to 1995

A day with at least 19.8 mm (0.8 in) of rain is expected about once in 2 years. A day with at least 47.3 mm (1.9 in) of rain is expected about once in 100 years.

Rainfall return levels at Kuna: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	19.8 mm (0.8 in)
5 years	26.6 mm (1.0 in)
10 years	31.3 mm (1.2 in)
25 years	37.5 mm (1.5 in)
50 years	42.3 mm (1.7 in)
100 years	47.3 mm (1.9 in)	Longer than the 60 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, 60 years of values from 1926 to 1995.

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: 45.7 mm (1.8 in) in 1938; 40.4 mm (1.6 in) in 1976; 39.1 mm (1.5 in) in 1987.

Station Changes

2 suspected

2 changes were suspected in the annual mean temperature of Kuna, at 1943 and 1982. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1943 ran 0.3 C (0.5 F) higher than in the years before (possible change).
Relative to 5 neighbouring stations, the station's annual mean temperature from 1982 ran 0.3 C (0.5 F) higher than in the years before (likely change).

Suspected changes in the annual mean temperature at Kuna, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1943	+0.3	+0.5	possible	5
1982	+0.3	+0.5	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.
