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

43 years with a frost

Across 43 years with a frost, the median last spring frost at Cloverdale falls on 27 February and the median first autumn frost on 3 December, which leaves a median of 280 days between them.

Fitted over all years, the growing season changes by -3.0 days per decade at this station.

Frost dates and growing season at Cloverdale
Measure	Median, all years	Earliest period	Recent period (1970 to 2023)	Recent against earliest	Fitted trend
Last spring frost	27 February	n/a	27 February	n/a	+2.5 days per decade
First autumn frost	3 December	n/a	1 December	n/a	-0.5 days per decade
Growing days	280 days	n/a	280 days	n/a	-3.0 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, 1956 to 2025

A day with at least 84.2 mm (3.3 in) of rain is expected about once in 2 years. A day with at least 196.0 mm (7.7 in) of rain is expected about once in 100 years.

Rainfall return levels at Cloverdale: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	84.2 mm (3.3 in)
5 years	114.2 mm (4.5 in)
10 years	134.1 mm (5.3 in)
25 years	159.1 mm (6.3 in)
50 years	177.6 mm (7.0 in)
100 years	196.0 mm (7.7 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 1956 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: 212.6 mm (8.4 in) in 1962; 168.9 mm (6.6 in) in 2014; 157.5 mm (6.2 in) in 1995.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Cloverdale, at 2019. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 2019 ran 0.6 C (1.1 F) lower than in the years before (likely change).

Suspected changes in the annual mean temperature at Cloverdale, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
2019	-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.

Climate Twins

2004 to 2023 against 1961 to 1990

Over 2004 to 2023, Cloverdale had a mean temperature of 16.4 C (61.5 F) and 906.5 mm (35.7 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Coimbra (Portugal, 9,007 km away), Cerocahui (Mexico, 1,888 km away) and Hvar (Croatia, 10,030 km away).

Climate twins of Cloverdale: stations whose 1961 to 1990 climate is closest to its 2004 to 2023 climate
Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Coimbra	Portugal	9,007 km (5,597 mi)	15.6 C (60.2 F)	984.2 mm (38.7 in)	1.25
Cerocahui	Mexico	1,888 km (1,173 mi)	16.1 C (60.9 F)	1,158.3 mm (45.6 in)	1.25
Hvar	Croatia	10,030 km (6,232 mi)	16.5 C (61.7 F)	730.4 mm (28.8 in)	1.29

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.
