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

48 years with a frost

Across 48 years with a frost, the median last spring frost at Mt Pleasant 1N falls on 14 April and the median first autumn frost on 23 October, which leaves a median of 193 days between them.

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

Frost dates and growing season at Mt Pleasant 1N
Measure	Median, all years	Earliest period	Recent period (1972 to 2025)	Recent against earliest	Fitted trend
Last spring frost	14 April	n/a	12 April	n/a	-1.6 days per decade
First autumn frost	23 October	n/a	23 October	n/a	+1.0 days per decade
Growing days	193 days	n/a	194 days	n/a	+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

59 years, 1954 to 2025

A day with at least 84.7 mm (3.3 in) of rain is expected about once in 2 years. A day with at least 223.4 mm (8.8 in) of rain is expected about once in 100 years.

Rainfall return levels at Mt Pleasant 1N: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	84.7 mm (3.3 in)
5 years	115.0 mm (4.5 in)
10 years	137.5 mm (5.4 in)
25 years	169.2 mm (6.7 in)
50 years	195.2 mm (7.7 in)
100 years	223.4 mm (8.8 in)	Longer than the 59 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, 59 years of values from 1954 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: 180.3 mm (7.1 in) in 1999; 177.8 mm (7.0 in) in 1996; 176.5 mm (6.9 in) in 1979.

No change in the annual mean temperature of this station was found against its neighbours.

Climate Twins

2000 to 2025 against 1961 to 1990

Over 2000 to 2025, Mt Pleasant 1N had a mean temperature of 15.3 C (59.5 F) and 1,521.2 mm (59.9 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Ripley (United States, 183 km away), Booneville (United States, 161 km away) and University (United States, 250 km away).

Climate twins of Mt Pleasant 1N: stations whose 1961 to 1990 climate is closest to its 2000 to 2025 climate
Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Ripley	United States	183 km (114 mi)	15.2 C (59.3 F)	1,476.3 mm (58.1 in)	0.56
Booneville	United States	161 km (100 mi)	15.5 C (59.8 F)	1,435.4 mm (56.5 in)	0.71
University	United States	250 km (155 mi)	15.4 C (59.7 F)	1,430.3 mm (56.3 in)	0.76

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.
