Your May weather guide
HotWeather in Varadero in May
May suits a Varadero holiday if you want hot weather and warm swimming water, and can accept some rain. Daytime highs average about 29°C, nights stay around 24°C and the sea is roughly 27°C. The catch is humidity and frequent wet days, rather than any shortage of warmth. For a UK traveller, this is a clear shift into summer clothing, but not the best choice if reliable dry weather matters more than heat.

Is May a good time to visit Varadero?

Warm sea, hot days and little evening cooling
May is comfortably warm enough for swimming, with sea temperatures averaging 27.2°C. That makes it a good fit if time in the water is central to your holiday. On land, humidity of 76% can make the warmth feel more tiring, so light, loose clothing and a relaxed pace are sensible. Keep strenuous plans away from midday and leave room for shade breaks. Around 19% of days reach 30°C, so hotter spells are a realistic possibility rather than the everyday expectation. Evenings offer limited cooling, with average lows of 24.1°C; pack mainly for warmth rather than expecting crisp nights. If you struggle to sleep in warm conditions, air conditioning is worth prioritising when choosing accommodation.
Expect sunshine, but keep plans flexible
Rain is the main compromise in May: about 14 days receive measurable rainfall, so it would be optimistic to plan around an entirely dry stay. That does not mean every wet day is a washout, and average sunshine of 7.3 hours a day leaves scope for time outdoors. With 13.1 hours of daylight, there is also a generous window for shifting plans when conditions change. Pack a lightweight waterproof and keep anything vulnerable to rain protected when you head out. The monthly figures do not tell you when rain will arrive, so avoid assuming it will always leave mornings or afternoons clear. May works best for travellers who can adjust their day rather than needing fixed outdoor plans.
