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

48 years with a frost

Across 48 years with a frost, the median last spring frost at Anson falls on 30 March and the median first autumn frost on 14 November, which leaves a median of 233 days between them.

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

Frost dates and growing season at Anson
Measure	Median, all years	Earliest period	Recent period (1987 to 2025)	Recent against earliest	Fitted trend
Last spring frost	30 March	n/a	1 April	n/a	+1.1 days per decade
First autumn frost	14 November	n/a	14 November	n/a	-0.1 days per decade
Growing days	233 days	n/a	230 days	n/a	-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

53 years, 1898 to 2025

A day with at least 67.7 mm (2.7 in) of rain is expected about once in 2 years. A day with at least 177.4 mm (7.0 in) of rain is expected about once in 100 years.

Rainfall return levels at Anson: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	67.7 mm (2.7 in)
5 years	92.2 mm (3.6 in)
10 years	110.2 mm (4.3 in)
25 years	135.2 mm (5.3 in)
50 years	155.6 mm (6.1 in)
100 years	177.4 mm (7.0 in)	Longer than the 53 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, 53 years of values from 1898 to 2025.

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: 157.0 mm (6.2 in) in 2023; 142.2 mm (5.6 in) in 1988; 138.4 mm (5.4 in) in 1978.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Anson, at 1971. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1971 ran 0.3 C (0.5 F) lower than in the years before (possible change).

Suspected changes in the annual mean temperature at Anson, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1971	-0.3	-0.5	possible	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.

Climate Twins

2004 to 2025 against 1961 to 1990

Over 2004 to 2025, Anson had a mean temperature of 18.0 C (64.5 F) and 656.8 mm (25.9 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Olney (United States, 125 km away), Robert Lee 4WSW (United States, 115 km away) and Brownwood 2NE (United States, 142 km away).

Climate twins of Anson: stations whose 1961 to 1990 climate is closest to its 2004 to 2025 climate
Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Olney	United States	125 km (78 mi)	18.1 C (64.6 F)	708.4 mm (27.9 in)	0.61
Robert Lee 4WSW	United States	115 km (71 mi)	18.0 C (64.3 F)	600.4 mm (23.6 in)	0.67
Brownwood 2NE	United States	142 km (88 mi)	18.4 C (65.0 F)	693.4 mm (27.3 in)	0.73

Twins are stations, not cities. A twin is one of the three stations at least 100 km away whose earlier climate is closest to this station's recent one, so a close match does not mean the two places look alike in other ways. A station move or a gap in a record can change that station's averages. The list describes past climate; it is not a forecast and does not say what caused any change. How twins are found, and a search for any station.
