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
72 years, 1943 to 2021
A day with at least 88.3 mm (3.5 in) of rain is expected about once in 2 years. A day with at least 274.4 mm (10.8 in) of rain is expected about once in 100 years.

Longer than the 72 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, 72 years of values from 1943 to 2021.
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: 227.8 mm (9.0 in) in 1947; 213.1 mm (8.4 in) in 1957; 208.0 mm (8.2 in) in 2017.
Station Changes
1 suspected
One change was suspected in the annual mean temperature of Naples, at 1952. Each is measured against neighbouring stations.
Relative to 5 neighbouring stations, the station's annual mean temperature from 1952 ran 0.5 C (1.0 F) lower than in the years before (likely change).

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
2006 to 2021 against 1961 to 1990
Over 2006 to 2021, Naples had a mean temperature of 23.8 C (74.8 F) and 1,559.7 mm (61.4 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are W Palm Beach Intl AP (United States, 168 km away), Ft Lauderdale (United States, 148 km away) and Hialeah (United States, 145 km away).
Climate twins of Naples: stations whose 1961 to 1990 climate is closest to its 2006 to 2021 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.
