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

72 years with a frost

Across 72 years with a frost, the median last spring frost at Cerro falls on 1 June and the median first autumn frost on 25 September, which leaves a median of 117 days between them.

In 1970 to 2021 the median growing season was 114 days. That is 1 day more than in 1912 to 1957.

Fitted over all years, the growing season changes by -1.3 days per decade at this station.

Frost dates and growing season at Cerro
Measure	Median, all years	Earliest period (1912 to 1957)	Recent period (1970 to 2021)	Recent against earliest	Fitted trend
Last spring frost	1 June	3 June	1 June	2 days earlier	+0.5 days per decade
First autumn frost	25 September	25 September	25 September	no change	-0.8 days per decade
Growing days	117 days	113 days	114 days	1 day more	-1.3 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

83 years, 1911 to 2021

A day with at least 25.4 mm (1.0 in) of rain is expected about once in 2 years. A day with at least 60.6 mm (2.4 in) of rain is expected about once in 100 years.

Rainfall return levels at Cerro: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	25.4 mm (1.0 in)
5 years	34.2 mm (1.3 in)
10 years	40.3 mm (1.6 in)
25 years	48.3 mm (1.9 in)
50 years	54.4 mm (2.1 in)
100 years	60.6 mm (2.4 in)	Longer than the 83 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, 83 years of values from 1911 to 2021.

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: 55.6 mm (2.2 in) in 1936; 51.8 mm (2.0 in) in 1943; 50.8 mm (2.0 in) in 1934.

Station Changes

No change in the annual mean temperature of this station was found against its neighbours.

Climate Twins

2000 to 2021 against 1961 to 1990

Over 2000 to 2021, Cerro had a mean temperature of 7.6 C (45.6 F) and 315.2 mm (12.4 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Ignacio 1 N (United States, 186 km away), Northdale (United States, 325 km away) and Moroni (United States, 609 km away).

Climate twins of Cerro: stations whose 1961 to 1990 climate is closest to its 2000 to 2021 climate
Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Ignacio 1 N	United States	186 km (116 mi)	7.5 C (45.6 F)	367.0 mm (14.4 in)	0.68
Northdale	United States	325 km (202 mi)	7.4 C (45.2 F)	311.4 mm (12.3 in)	0.69
Moroni	United States	609 km (378 mi)	7.8 C (46.1 F)	236.6 mm (9.3 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.
