Varadero sää — syyskuu

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.

Regulars are specific this month runs close to a genuine coin flip, some days nice, sunny and warm while others turn cool and windy, especially if a cold front happens to pass through, a light jacket or wrap worth having for evenings regardless. Our row backs that mild, genuinely dry read, 26C over 19.4C nights feeling 20C, with rain light at 38.8mm across 7.7 days and a real 20.8 kph wind. Regulars are honest January through March counts as genuinely iffy for beach lovers specifically, with some recommending heading further south for more assured warm beach weather. The sea sits at a mild 24.7C. The record: 9.2 hours of sun, humidity 74 percent and AQI 36.

December here is genuinely two different months depending on the week, and regulars name the cause: a cold front, El Norte, can drop through at any point, bringing strong wind, rain, rough water too choppy to swim in, and evenings that fall to around 15C even while the daytime otherwise holds. Early December tends toward the mid-twenties and calm; some recent years have turned cold and wet from around the 10th onward. Our row averages across both possibilities - 26.9C over 20.5C, with 28mm of rain across 6.2 days and a real 20.3 kph wind - so a warm week and a blustery one both fit inside it. The sea is 25.3C on a calm day. Checking the week's forecast matters more than the month here. The record: humidity 76 percent, 9.1 hours of sun and AQI 37.

November is hot and sunny with a bit of rain some evenings, and regulars are specific that the wet mostly falls at night - which is what our 9.4 precipitation days over 38.7mm actually describes, four millimetres a day, largely after dark. Days are very warm at 28C, nights cooler at 21.8C. The risk everyone asks about closes now: hurricane season officially ends on the 30th of November, and once October is behind you the odds drop sharply, so a forecast that looks dismal on paper is reading the tail of a season rather than the middle. The other date is commercial - high season starts mid-December, so November buys the same weather cheaper. The record: humidity 76 percent, 9.5 hours of sun, a 20.6 kph wind and a 27C sea.

March is the month Varadero regulars name: sunny, hardly any rain, and showers that last twenty or thirty minutes when they come - our row gives 29.5mm across 3.8 precipitation days. Their low-to-mid-30s reports are the hot days rather than the average, which our row puts at 28.1C over 20C. The pattern worth planning around is daily: the wind gets up around noon to 15 or 20 knots, a warm breeze that drops away in the early evening, and on the strongest days the beach goes red-flagged and swimming stops. Our 21.3 kph is that averaged. On seaweed they are reassuring - light except after high winds, and raked and buried at dawn. The record: humidity 71 percent, 10.6 hours of sun, a 26.4C sea and AQI 40.
