In 1995 to 2025 the median growing season was 235 days. That is 34 days more than in 1921 to 1950.

Fitted over all years, the growing season changes by +4.9 days per decade at this station.

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

104 years, 1921 to 2025

A day with at least 53.6 mm (2.1 in) of rain is expected about once in 2 years. A day with at least 101.6 mm (4.0 in) of rain is expected about once in 100 years.

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 104 years of values from 1921 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: 103.4 mm (4.1 in) in 2021; 99.8 mm (3.9 in) in 1995; 97.0 mm (3.8 in) in 1935.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Lyon - St Exupery, at 1999. Each is measured against neighbouring stations.

  • Relative to 5 neighbouring stations, the station's annual mean temperature from 1999 ran 0.3 C (0.6 F) higher than in the years before (likely change).

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, Lyon - St Exupery had a mean temperature of 13.6 C (56.4 F) and 849.1 mm (33.4 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Montelimar (France, 130 km away), Placerville (United States, 9,189 km away) and Bijie (China, 8,601 km away).

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.
