Cuba in May: what to expect

May is the handover month. The dry season that runs November to April ends, humidity climbs and the first proper afternoon storms arrive, usually short and heavy rather than all-day rain. Mornings are often clear enough for the beach or a city walk; the sky builds through the early afternoon.

Temperatures sit in the low thirties by day and the low twenties at night across the west and centre. Oriente — Santiago de Cuba, Baracoa, Holguín — is hotter and wetter, and Baracoa is damp for much of the year anyway. The Escambray hills behind Trinidad stay a few degrees cooler, which makes them a reasonable escape on a sticky day.

The bigger practical issue in 2026 is not the rain but the power supply. Heat without fans or air conditioning is the real summer problem, and May is when that starts to bite. Plan rooms with a generator or a breeze, and keep a torch and a power bank charged.

May is one of the two quietest months in Cuba, along with September and October. The winter charter crowds are gone, the hurricane season has not started, and the heat keeps some people away. You will not queue for the classic Havana sights and you can often decide on a casa particular the same day.

Prices follow. This is the cheapest window of the year for rooms outside the 1 May holiday, and the low season runs through to November. Bring cash: cards issued by US banks do not work, and even non-US cards fail more often than travellers expect, so budget the whole trip in euros or Canadian dollars and change what you need.

The month is dominated by 1 May, International Workers' Day. Havana holds mass rallies in the Plaza de la Revolución, and some shops, museums and transport run reduced hours. It is a spectacle if you are interested, and an inconvenience if you are not — check locally before planning a travel day around it.

Beyond the holiday, May is thin on fixed events. Havana's cultural calendar keeps going with concerts, theatre and gallery openings, and the International Workers' Day weekend often brings music to the capital, but nothing on the scale of July's Santiago carnival or December's film festival. Check listings when you arrive rather than booking around a specific date.

Havana works in May if you accept the heat and start early. Old Havana, the Malecón and the museums are all quieter than in winter, and the afternoon storm is a good excuse for a long lunch. Book a room with air conditioning or at least a fan and cross-ventilation.

Trinidad and the Escambray hills are a sensible pairing: the town is hot but the hills are cooler, and the south coast is slightly warmer than Havana. Cienfuegos and Santa Clara fit the same central route. In Oriente, Santiago de Cuba is lively and hot, while Baracoa is the wettest option in the country — go only if you do not mind rain and want the road-and-sea scenery.

Beaches are still good in May. Varadero and the cayos are warm, the water is comfortable, and the crowds are gone. The trade-off is that this is the start of the wet season, so expect a shower most afternoons.

Pack for heat, humidity and rain in the same day. Light, quick-drying clothes, a compact umbrella or rain shell, and shoes that cope with wet streets. Sun protection matters more than in winter, and mosquito repellent is worth carrying, especially around dusk and near standing water.

Bring the practical kit: a power bank, a torch or headlamp, a refillable water bottle, and enough cash for the whole trip in a currency you can change. A small first-aid kit with rehydration salts is useful in the heat. If you take medication, bring more than you need — pharmacies are poorly stocked.

April is the last dry month, with fewer visitors than winter and better weather than May. June opens the hurricane season and is more humid, though crowds and prices stay low. July brings Santiago's carnival and the 26 July holiday, plus the highest heat of the year.

If your dates are flexible, the strongest window in Cuba is November to April. May is a compromise: cheaper and quieter, but wetter, hotter and more exposed to the power and fuel problems that shape any 2026 trip.
