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

20 years with a frost

Across 20 years with a frost, the median last spring frost at El Cuarto falls on 11 March and the median first autumn frost on 14 November, which leaves a median of 243 days between them.

Frost dates and growing season at El Cuarto
Measure	Median, all years	Earliest period	Recent period (1965 to 2008)	Recent against earliest	Fitted trend
Last spring frost	11 March	n/a	11 March	n/a	n/a
First autumn frost	14 November	n/a	14 November	n/a	n/a
Growing days	243 days	n/a	243 days	n/a	n/a

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, 1948 to 2008

A day with at least 42.1 mm (1.7 in) of rain is expected about once in 2 years. A day with at least 98.0 mm (3.9 in) of rain is expected about once in 100 years.

Rainfall return levels at El Cuarto: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	42.1 mm (1.7 in)
5 years	56.2 mm (2.2 in)
10 years	65.9 mm (2.6 in)
25 years	78.6 mm (3.1 in)
50 years	88.2 mm (3.5 in)
100 years	98.0 mm (3.9 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 1948 to 2008.

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: 111.0 mm (4.4 in) in 1960; 84.8 mm (3.3 in) in 1970; 79.8 mm (3.1 in) in 1967.
