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

52 years with a frost

Across 52 years with a frost, the median last spring frost at Anvil Rch falls on 1 April and the median first autumn frost on 6 November, which leaves a median of 221 days between them.

Fitted over all years, the growing season changes by +0.2 days per decade at this station.

Frost dates and growing season at Anvil Rch
Measure	Median, all years	Earliest period	Recent period (1987 to 2025)	Recent against earliest	Fitted trend
Last spring frost	1 April	n/a	30 March	n/a	-0.7 days per decade
First autumn frost	6 November	n/a	5 November	n/a	-0.4 days per decade
Growing days	221 days	n/a	221 days	n/a	+0.2 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

74 years, 1943 to 2025

A day with at least 36.3 mm (1.4 in) of rain is expected about once in 2 years. A day with at least 92.9 mm (3.7 in) of rain is expected about once in 100 years.

Rainfall return levels at Anvil Rch: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	36.3 mm (1.4 in)
5 years	51.1 mm (2.0 in)
10 years	61.1 mm (2.4 in)
25 years	73.8 mm (2.9 in)
50 years	83.4 mm (3.3 in)
100 years	92.9 mm (3.7 in)	Longer than the 74 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, 74 years of values from 1943 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: 109.2 mm (4.3 in) in 1962; 76.7 mm (3.0 in) in 2022; 73.7 mm (2.9 in) in 2021.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1993 ran 0.4 C (0.7 F) lower than in the years before (likely change).

Year	Shift (C)	Shift (F)	Strength	Neighbours
1993	-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.

Climate Twins

2006 to 2025 against 1961 to 1990

Over 2006 to 2025, Anvil Rch had a mean temperature of 19.3 C (66.8 F) and 242.8 mm (9.6 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Colonia Morelos (Mexico, 243 km away), Falcon Fld (United States, 165 km away) and Wikieup (United States, 367 km away).

Climate twins of Anvil Rch: stations whose 1961 to 1990 climate is closest to its 2006 to 2025 climate
Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Colonia Morelos	Mexico	243 km (151 mi)	18.8 C (65.8 F)	331.7 mm (13.1 in)	0.77
Falcon Fld	United States	165 km (103 mi)	19.4 C (66.9 F)	208.2 mm (8.2 in)	0.85
Wikieup	United States	367 km (228 mi)	18.9 C (66.0 F)	274.3 mm (10.8 in)	0.90

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.
