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

47 years, 1960 to 2025

A day with at least 88.6 mm (3.5 in) of rain is expected about once in 2 years. A day with at least 267.4 mm (10.5 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, 47 years of values from 1960 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: 297.2 mm (11.7 in) in 2015; 195.3 mm (7.7 in) in 1992; 187.5 mm (7.4 in) in 1991.

Climate Twins

1996 to 2024 against 1961 to 1990

Over 1996 to 2024, Mayport Pilot STN had a mean temperature of 21.4 C (70.6 F) and 1,129.9 mm (44.5 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Matagorda #2 (United States, 1,420 km away), Refugio (United States, 1,554 km away) and Pt Comfort (United States, 1,476 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.
