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

68 years with a frost

Across 68 years with a frost, the median last spring frost at Carville 2 SW falls on 16 February and the median first autumn frost on 2 December, which leaves a median of 292 days between them.

In 1982 to 2025 the median growing season was 302 days. That is 12 days more than in 1939 to 1973.

Fitted over all years, the growing season changes by +2.9 days per decade at this station.

First autumn frost2 December1 December9 December8 days later+0.9 days per decade
Growing days292 days290 days302 days12 days more+2.9 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

83 years, 1938 to 2025

A day with at least 102.6 mm (4.0 in) of rain is expected about once in 2 years. A day with at least 212.3 mm (8.4 in) of rain is expected about once in 100 years.

50 years196.7 mm (7.7 in)

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 83 years of values from 1938 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: 206.5 mm (8.1 in) in 2015; 198.1 mm (7.8 in) in 1997; 188.5 mm (7.4 in) in 2014.

Station Changes

2 suspected

2 changes were suspected in the annual mean temperature of Carville 2 SW, at 1954 and 1977. Each is measured against neighbouring stations.

  • Relative to 5 neighbouring stations, the station's annual mean temperature from 1954 ran 0.5 C (0.8 F) higher than in the years before (likely change).
  • Relative to 5 neighbouring stations, the station's annual mean temperature from 1977 ran 0.3 C (0.6 F) lower 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

2008 to 2025 against 1961 to 1990

Over 2008 to 2025, Carville 2 SW had a mean temperature of 20.9 C (69.6 F) and 1,756.1 mm (69.1 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are New Orleans Audubon (United States, 101 km away), St Bernard (United States, 130 km away) and Galliano (United States, 114 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.
