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.

Rainfall Return Levels

75 years, 1949 to 2025

A day with at least 86.1 mm (3.4 in) of rain is expected about once in 2 years. A day with at least 203.5 mm (8.0 in) of rain is expected about once in 100 years.

Rainfall return levels at Clermont 9 S: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	86.1 mm (3.4 in)
5 years	114.0 mm (4.5 in)
10 years	133.9 mm (5.3 in)
25 years	160.5 mm (6.3 in)
50 years	181.6 mm (7.1 in)
100 years	203.5 mm (8.0 in)	Longer than the 75 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, 75 years of values from 1949 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: 215.9 mm (8.5 in) in 2017; 185.2 mm (7.3 in) in 1950; 175.3 mm (6.9 in) in 1988.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Clermont 9 S, at 2014. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 2014 ran 0.5 C (0.9 F) higher than in the years before (likely change).

Year	Shift (C)	Shift (F)	Strength	Neighbours
2014	+0.5	+0.9	likely	5

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

2010 to 2024 against 1961 to 1990

Over 2010 to 2024, Clermont 9 S had a mean temperature of 23.5 C (74.3 F) and 1,245.0 mm (49.0 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are St Petersburg (United States, 117 km away), Punta Gorda 4 ESE (United States, 173 km away) and Ft Myers Page Fld AP (United States, 208 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.
