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

24 years with a frost

Across 24 years with a frost, the median last spring frost at Las Nieves falls on 27 February and the median first autumn frost on 25 November, which leaves a median of 266 days between them.

Frost dates and growing season at Las Nieves
Measure	Median, all years	Earliest period	Recent period (1969 to 2007)	Recent against earliest	Fitted trend
Last spring frost	27 February	n/a	27 February	n/a	n/a
First autumn frost	25 November	n/a	25 November	n/a	n/a
Growing days	266 days	n/a	266 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

32 years, 1969 to 2008

A day with at least 29.3 mm (1.2 in) of rain is expected about once in 2 years. A day with at least 68.7 mm (2.7 in) of rain is expected about once in 100 years.

Rainfall return levels at Las Nieves: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	29.3 mm (1.2 in)
5 years	41.8 mm (1.6 in)
10 years	49.2 mm (1.9 in)
25 years	57.7 mm (2.3 in)
50 years	63.5 mm (2.5 in)	Longer than the 32 years of record
100 years	68.7 mm (2.7 in)	Longer than the 32 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, 32 years of values from 1969 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: 57.9 mm (2.3 in) in 2007; 56.9 mm (2.2 in) in 2008; 49.8 mm (2.0 in) in 2004.
