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

103 years with a frost

Across 103 years with a frost, the median last spring frost at Bordeaux-Merignac falls on 28 March and the median first autumn frost on 13 November, which leaves a median of 235 days between them.

In 1995 to 2025 the median growing season was 258 days. That is 45 days more than in 1906 to 1950.

Fitted over all years, the growing season changes by +5.3 days per decade at this station.

Frost dates and growing season at Bordeaux-Merignac
Measure	Median, all years	Earliest period (1906 to 1950)	Recent period (1995 to 2025)	Recent against earliest	Fitted trend
Last spring frost	28 March	1 April	8 March	24 days earlier	-2.6 days per decade
First autumn frost	13 November	29 October	25 November	27 days later	+2.7 days per decade
Growing days	235 days	213 days	258 days	45 days more	+5.3 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

118 years, 1901 to 2025

A day with at least 39.1 mm (1.5 in) of rain is expected about once in 2 years. A day with at least 82.2 mm (3.2 in) of rain is expected about once in 100 years.

Rainfall return levels at Bordeaux-Merignac: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	39.1 mm (1.5 in)
5 years	50.2 mm (2.0 in)
10 years	57.7 mm (2.3 in)
25 years	67.4 mm (2.7 in)
50 years	74.8 mm (2.9 in)
100 years	82.2 mm (3.2 in)

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 118 years of values from 1901 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: 87.6 mm (3.4 in) in 1992; 81.7 mm (3.2 in) in 1990; 79.0 mm (3.1 in) in 1999.

Station Changes

2 suspected

2 changes were suspected in the annual mean temperature of Bordeaux-Merignac, at 1988 and 2006. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1988 ran 0.4 C (0.8 F) higher than in the years before (likely change).
Relative to 5 neighbouring stations, the station's annual mean temperature from 2006 ran 0.1 C (0.2 F) lower than in the years before (possible change).

Suspected changes in the annual mean temperature at Bordeaux-Merignac, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1988	+0.4	+0.8	likely	5
2006	-0.1	-0.2	possible	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

2011 to 2025 against 1961 to 1990

Over 2011 to 2025, Bordeaux-Merignac had a mean temperature of 14.8 C (58.7 F) and 887.3 mm (34.9 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Zadar (Croatia, 1,153 km away), Saint Helena (United States, 9,142 km away) and Ourense (Spain, 742 km away).

Climate twins of Bordeaux-Merignac: stations whose 1961 to 1990 climate is closest to its 2011 to 2025 climate
Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Zadar	Croatia	1,153 km (716 mi)	14.8 C (58.7 F)	916.3 mm (36.1 in)	0.71
Saint Helena	United States	9,142 km (5,681 mi)	14.9 C (58.7 F)	902.1 mm (35.5 in)	0.72
Ourense	Spain	742 km (461 mi)	14.2 C (57.6 F)	811.8 mm (32.0 in)	0.88

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.
