Hot days, with little cooling after dark

For a UK traveller, the change from home is substantial: London's average March high is 10.5°C, compared with 27.3°C in Barbados. That suits a holiday built around swimming and time outdoors, though humidity of 73% means the warmth can feel close. Keep the middle of the day flexible, with shade and breaks rather than sustained exertion. Loose, breathable clothing makes sense, and average night lows of 24.5°C mean evenings are still warm rather than a chance to cool down properly. March is not among Barbados's hottest months, so it is a sensible choice if you want heat without deliberately aiming for the warmest conditions.

Good swimming weather, but leave room for rain

The sea averages 26.7°C, making March a straightforward choice if swimming is central to your plans. Sunshine averages about 6.8 hours within 11.9 hours of daylight: there is useful time for outdoor plans, but daylight should not be confused with uninterrupted sun. About 7 days receive measurable rain, so allow some flexibility rather than expecting every day to stay dry. The figures do not tell you when rain will arrive or how long it will last. Pack sun protection alongside a light rain layer, and keep plans easy to rearrange. The balance favours a warm outdoor holiday, provided occasional wet weather would not spoil it for you.
