Clima en La Habana en septiembre

Havana-forum threads on September weather describe a genuinely reliable daily rhythm: clear skies through the morning, clouds building by early afternoon, and a heavy downpour arriving around 5pm that typically clears within a couple of hours, sunny or lightly cloudy conditions the rest of the day. Regulars call September a great time overall, slightly cooler than peak summer even though still hot and humid. Hurricane season runs June through November, and while a major storm has hit Havana directly before, posters are consistent most Septembers pass without a direct impact, several longtime visitors reporting multiple storm-free trips over the years. Cuba's hurricane response system gets specific praise for how efficiently the island prepares. The record: 31.8C days feeling like a punishing 37C, 23.7C nights, 125mm across 19.1 days, 79 percent humidity, a 30.4C sea and 10.2 hours of sun.

December opens the high season here, which runs to April, and regulars split the month in two: early to mid December is good value, and prices climb steeply into Christmas and New Year, when the city fills and rooms have to be booked with the flights. The weather is the reason - the hurricane season is over, and 27.6C by day with 39mm of rain across 5.8 days makes walking the old town pleasant rather than punishing. Nights drop to 18.8C and the boards suggest a sweater for the cool ones, which surprises people. A 20 kph breeze off the Malecon helps. The record: humidity 74 percent, 9.2 hours of sun, a 27.4C sea and AQI 38.

Havana-forum threads on June weather confirm it's hot and humid with a reliable afternoon or evening downpour most days, though posters are consistent most visitors only catch a brief overnight or late-day shower rather than anything that disrupts a full day of sightseeing. June technically opens hurricane season, but regulars are quick to note the actual odds of a storm hitting this early are genuinely low, the real risk window running mid-August through October instead. The old town's colonnaded streets offer decent shade for a hot midday walk, and posters recommend timing the Malecon seafront for early morning or evening rather than the peak heat of the afternoon. Regulars call June a fine month provided a visitor accepts the daily rain as routine rather than a trip risk. The record: 31.7C days feeling like a punishing 37C, 23.5C nights, a notably high 146mm across 19.2 days, a 29.7C sea and 77 percent humidity.

March is one of the two months Cuba regulars name, with April, and their reasons suit a city rather than a beach: comfortable rather than hot, humidity low for the tropics, very little rain, and noticeably fewer insects than later in the year - all of which matters when the plan is walking Habana Vieja for hours. Our row gives 28.8C days reading as 30C, 18.6C nights at 68 percent humidity, and 18.2mm of rain across 3.4 days. The one March crowd note is Canadian school break, which fills the resorts and touches Havana less. The record: 21.1 kph of wind, 10.8 hours of sun and a 26.6C sea.

February is the month Havana-forum regulars send people to when the trip has to be half city and half beach: warm enough for the water, comfortable enough to walk the streets all day, and nothing like the summer. What visitors report is 75 to 80F afternoons against nights nearer 65F, which is why the packing advice is long trousers, a light sweater for after dark, and a light rain shell. The variable is a passing cold front - it can put a genuinely cool day or two into the middle of the month, then leave. February and March are also named as the better pair for western Cuba, with little rain. The record: 28C days, 18.3C nights, 3.9 precipitation days, a 26.8C sea, a 21 kph breeze, AQI 41.
