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

85 years with a frost

Across 85 years with a frost, the median last spring frost at Monroe Rgnl AP falls on 7 March and the median first autumn frost on 12 November, which leaves a median of 253 days between them.

In 1996 to 2025 the median growing season was 263 days. That is 25 days more than in 1930 to 1970.

Fitted over all years, the growing season changes by +2.5 days per decade at this station.

Frost dates and growing season at Monroe Rgnl AP
Measure	Median, all years	Earliest period (1930 to 1970)	Recent period (1996 to 2025)	Recent against earliest	Fitted trend
Last spring frost	7 March	14 March	27 February	15 days earlier	-1.5 days per decade
First autumn frost	12 November	5 November	17 November	12 days later	+1.0 days per decade
Growing days	253 days	238 days	263 days	25 days more	+2.5 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

86 years, 1930 to 2025

A day with at least 90.9 mm (3.6 in) of rain is expected about once in 2 years. A day with at least 226.6 mm (8.9 in) of rain is expected about once in 100 years.

Rainfall return levels at Monroe Rgnl AP: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	90.9 mm (3.6 in)
5 years	121.7 mm (4.8 in)
10 years	144.2 mm (5.7 in)
25 years	175.1 mm (6.9 in)
50 years	200.0 mm (7.9 in)
100 years	226.6 mm (8.9 in)	Longer than the 86 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, 86 years of values from 1930 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: 275.8 mm (10.9 in) in 2016; 188.0 mm (7.4 in) in 2008; 186.4 mm (7.3 in) in 1987.

Climate Twins

2011 to 2025 against 1961 to 1990

Over 2011 to 2025, Monroe Rgnl AP had a mean temperature of 19.5 C (67.0 F) and 1,424.0 mm (56.1 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Natchitoches (United States, 130 km away), Alexandria (United States, 139 km away) and Bay Saint Louis (United States, 355 km away).

Bay Saint Louis	United States	355 km (221 mi)	19.3 C (66.8 F)	1,456.3 mm (57.3 in)	0.79

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.
