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

55 years with a frost

Across 55 years with a frost, the median last spring frost at Bilbao Aeropuerto falls on 8 March and the median first autumn frost on 4 December, which leaves a median of 274 days between them.

Fitted over all years, the growing season changes by +5.7 days per decade at this station.

Frost dates and growing season at Bilbao Aeropuerto
Measure	Median, all years	Earliest period	Recent period (1977 to 2017)	Recent against earliest	Fitted trend
Last spring frost	8 March	n/a	23 February	n/a	-4.5 days per decade
First autumn frost	4 December	n/a	5 December	n/a	+1.2 days per decade
Growing days	274 days	n/a	289 days	n/a	+5.7 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

71 years, 1948 to 2025

A day with at least 59.3 mm (2.3 in) of rain is expected about once in 2 years. A day with at least 149.4 mm (5.9 in) of rain is expected about once in 100 years.

Rainfall return levels at Bilbao Aeropuerto: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	59.3 mm (2.3 in)
5 years	77.5 mm (3.1 in)
10 years	91.6 mm (3.6 in)
25 years	112.2 mm (4.4 in)
50 years	129.8 mm (5.1 in)
100 years	149.4 mm (5.9 in)	Longer than the 71 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, 71 years of values from 1948 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: 172.6 mm (6.8 in) in 1953; 137.2 mm (5.4 in) in 1959; 108.1 mm (4.3 in) in 2010.

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.
