Warmer than London, without strong heat

Bermuda's average daytime high is 5°C above London's in May, so the difference should be noticeable without making the weather feel especially hot. Light clothing is a sensible starting point, with a light layer for cooler evenings. Average night-time temperatures stay close to daytime levels, although the colder nights can fall to around 18°C or below. Humidity averages 79%, so the air may feel damper than the mild temperatures suggest. This suits travellers who prefer being outdoors without strong heat; if your idea of a holiday depends on hot afternoons, May is likely to feel a little restrained.

Allow for rain, not just sunshine

Rain is a meaningful part of the May trade-off: about 10 days receive at least 1 mm, so a completely dry stay is not something to bank on. That does not mean every wet day is a washout, but the figures do not tell you when rain will arrive or how long it will last. Keep outdoor plans flexible and take a lightweight waterproof rather than relying only on warm-weather clothes. There is about 5.9 hours of sunshine within 13.7 hours of daylight each day, leaving plenty of daylight but no promise of clear skies throughout. May suits a flexible itinerary better than a holiday built entirely around sunbathing.

The sea is the main catch

At an average of 21.8°C, the sea is bracing rather than comfortably warm. If you are happy with a fresh-feeling dip, swimming may still be enjoyable; if you like lingering in warm water, this is the main reason to hesitate. Sea temperatures vary between 21°C and 23°C from year to year, so do not assume the average will match your stay exactly. June, July and August rate better overall for weather here, making them sensible alternatives if your dates are flexible. May remains a reasonable choice when mild warmth matters more to you than warm-water swimming or dependable sunshine.
