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 Morgan City falls on 13 February and the median first autumn frost on 8 December, which leaves a median of 296 days between them.
Fitted over all years, the growing season changes by +4.7 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
114 years, 1905 to 2019
A day with at least 102.1 mm (4.0 in) of rain is expected about once in 2 years. A day with at least 286.5 mm (11.3 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, 114 years of values from 1905 to 2019.
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: 395.0 mm (15.6 in) in 1927; 254.5 mm (10.0 in) in 1995; 231.1 mm (9.1 in) in 1980.

Climate Twins
2003 to 2019 against 1961 to 1990
Over 2003 to 2019, Morgan City had a mean temperature of 20.7 C (69.3 F) and 1,380.6 mm (54.4 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Jacksonville Cecil Fld NAS (United States, 897 km away), Live Oak (United States, 791 km away) and Houston William P Hobby AP (United States, 397 km away).
Climate twins of Morgan City: stations whose 1961 to 1990 climate is closest to its 2003 to 2019 climate
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.
