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

36 years with a frost

Across 36 years with a frost, the median last spring frost at Saigo falls on 4 April and the median first autumn frost on 13 December, which leaves a median of 256 days between them.

Fitted over all years, the growing season changes by -3.3 days per decade at this station.

Frost dates and growing season at Saigo
Measure	Median, all years	Earliest period	Recent period (1959 to 1989)	Recent against earliest	Fitted trend
Last spring frost	4 April	n/a	4 April	n/a	+1.0 days per decade
First autumn frost	13 December	n/a	11 December	n/a	-2.4 days per decade
Growing days	256 days	n/a	255 days	n/a	-3.3 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

58 years, 1951 to 2024

A day with at least 105.7 mm (4.2 in) of rain is expected about once in 2 years. A day with at least 276.0 mm (10.9 in) of rain is expected about once in 100 years.

Rainfall return levels at Saigo: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	105.7 mm (4.2 in)
5 years	143.5 mm (5.6 in)
10 years	171.4 mm (6.7 in)
25 years	210.2 mm (8.3 in)
50 years	241.9 mm (9.5 in)
100 years	276.0 mm (10.9 in)	Longer than the 58 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, 58 years of values from 1951 to 2024.

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: 281.9 mm (11.1 in) in 2020; 254.0 mm (10.0 in) in 2021; 203.5 mm (8.0 in) in 1988.

Station Changes

2 suspected

2 changes were suspected in the annual mean temperature of Saigo, at 1970 and 1982. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1970 ran 0.3 C (0.5 F) lower than in the years before (likely change).
Relative to 5 neighbouring stations, the station's annual mean temperature from 1982 ran 0.2 C (0.3 F) higher than in the years before (likely change).

Suspected changes in the annual mean temperature at Saigo, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1970	-0.3	-0.5	likely	5
1982	+0.2	+0.3	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.
