Warm days, with little cooling after dark

Average daytime highs of 27.7°C are noticeably warmer than London's 21.8°C in July, but humidity of 82% is an important part of how the heat feels. This suits travellers comfortable with humid warmth more than those who want cool conditions for being active. Nights average 25.6°C, so do not expect much relief after sunset; accommodation with effective cooling is a sensible priority. Pack loose, breathable clothes and keep strenuous plans away from midday if you find heat tiring. Evenings call for light clothing rather than warm layers. July is hot, but it is not Grenada's warmest month, so choosing it solely for peak heat makes little sense.

Expect rain to shape your plans

Rain is the main compromise in July: about 23 days receive at least 1 mm, so a rain-free holiday is not a sensible expectation. That does not mean continuous rain, but the figures do not tell you when showers will arrive or how long they will last. Keep outdoor plans flexible rather than assuming mornings or afternoons will stay dry. There is still about 5.6 hours of sunshine within 12.6 hours of daylight, so July is not without bright spells. A lightweight waterproof and protection for belongings are useful, though heavy rainwear may feel uncomfortable in the humidity. This month suits a relaxed schedule better than plans that depend on uninterrupted sunshine.
