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

70 years with a frost

Across 70 years with a frost, the median last spring frost at Havana falls on 21 April and the median first autumn frost on 17 October, which leaves a median of 180 days between them.

In 1936 to 1965 the median growing season was 180 days. That is 5 days fewer than in 1893 to 1925.

Fitted over all years, the growing season changes by -0.8 days per decade at this station.

Frost dates and growing season at Havana
Measure	Median, all years	Earliest period (1893 to 1925)	Recent period (1936 to 1965)	Recent against earliest	Fitted trend
Last spring frost	21 April	17 April	21 April	4 days later	+1.2 days per decade
First autumn frost	17 October	15 October	18 October	3 days later	+0.4 days per decade
Growing days	180 days	185 days	180 days	5 days fewer	-0.8 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

71 years, 1893 to 1965

A day with at least 57.6 mm (2.3 in) of rain is expected about once in 2 years. A day with at least 157.4 mm (6.2 in) of rain is expected about once in 100 years.

Rainfall return levels at Havana: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	57.6 mm (2.3 in)
5 years	76.5 mm (3.0 in)
10 years	91.6 mm (3.6 in)
25 years	114.4 mm (4.5 in)
50 years	134.4 mm (5.3 in)
100 years	157.4 mm (6.2 in)	Longer than the 71 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, 71 years of values from 1893 to 1965.

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: 182.9 mm (7.2 in) in 1937; 129.5 mm (5.1 in) in 1899; 114.3 mm (4.5 in) in 1917.
