Hot days, with little cooling after dark

Grenada feels substantially warmer than London in June, with average daytime highs 8.3°C higher. The catch is humidity at 81%: even without exceptional temperatures, walking around can feel sticky, so keep your pace easy and leave room for shade and breaks at midday. Pack loose, breathable clothes rather than relying on the layers you might wear during a British summer. Nights remain warm enough that cooling in your accommodation deserves attention; do not expect the evening to bring much relief from the heat. June suits travellers who enjoy sustained warmth, but it is less comfortable if you depend on cool nights to sleep well.

Plan around rain, not uninterrupted sunshine

June is wet, so a rigid schedule of outdoor days is the main risk. About 4.6 hours of sunshine within 12.7 hours of daylight leaves plenty of time when the sun is not out, though that does not mean it rains continuously. Keep swimming and other outdoor plans movable, and pack a light waterproof that will not feel too heavy in the humidity. The monthly figures cannot tell you which part of the day will be dry, so avoid building your plans around an assumed daily rain pattern. June works best if warmth matters more to you than clear skies; for a better overall weather balance, consider March, February or April.
