Warm days rather than routine extreme heat

Pack mainly light clothing: average daytime highs of 24.7°C favour spending time outdoors without planning the whole day around extreme heat. Only 3% of days reach 30°C, although hotter spells remain possible, so do not assume every afternoon will be mild. Humidity averages 79%, which may make walking feel more tiring than the temperature alone suggests. Keep strenuous activity for when you feel coolest, and allow for shade breaks around midday. With average night lows of 21.5°C, evenings usually call for light layers rather than heavy clothing. If you dislike warm sleeping conditions, check the cooling arrangements before booking accommodation.

Very little rain, but not uninterrupted sunshine

Rain is unlikely to dictate your plans in August, with about 0 rainy days in a typical month. That makes it a sensible choice if avoiding wet weather is your main reason for travelling. You can leave a heavy waterproof out of the usual packing list, though a dry monthly average is not a promise about every day. Expect about 8.6 hours of sunshine within 13.0 hours of daylight: plenty of time outdoors, but not continuous clear skies. Plan for sun cream, sunglasses and a hat, and use shaded breaks rather than treating the moderate air temperature as a reason to stay in direct sun.

A swimming month with warm evenings

The sea averages 22.3°C, putting August in the comfortable swimming category rather than the bracing one. Its year-to-year range of 22°C to 23°C also suggests that water temperature is a fairly consistent reason to choose this month. Personal preference still matters: if you like bath-warm water, it may feel cool as you get in. For travellers who want to alternate swimming with time out of the water, the combination of warm air and very little rain is useful. Evenings remain warm enough that changing out of wet swimwear and into light, dry clothing is a more relevant consideration than packing winter layers.
