September is poor for Havana.
September is the wettest and one of the riskiest months — hot and very humid at around 31°C by day and 23°C at night, with heavy rainfall (about 165mm) and the Atlantic hurricane season at its peak (September-October).
It is low season, with the fewest crowds and lowest prices, but the climate and storm risk are the real downsides.

If you go, monitor forecasts closely, build in flexibility, and take out travel insurance that covers weather and cancellations.

Havana in September — Full Picture
September is the wettest and one of the riskiest months — hot and very humid at around 31°C by day and 23°C at night, with heavy rainfall (about 165mm) and the Atlantic hurricane season at its peak (September-October).
It is low season, with the fewest crowds and lowest prices, but the climate and storm risk are the real downsides. Hurricanes and tropical storms can bring serious disruption — flooding along the Malecón, power and water outages, and travel delays. If you go, monitor forecasts closely, build in flexibility, and take out travel insurance that covers weather and cancellations.
Between storms, mornings can still be sunny and the warm sea (around 29°C) is pleasant, but this is the hardest month to plan reliably. Most travelers who can choose their dates avoid September-October.
The usual realities are amplified here: outages are more likely, internet is scarce (offline maps), it's cash-only, and US travelers need an authorized category.
What to Wear & What to Pack
