Expect heat that lasts into the evening
Alicante reaches 30°C on 45% of August days, so the average high is not a ceiling. The hottest days can make prolonged walking uncomfortable, particularly with humidity at 68%. Plan anything active for the morning, leave room for shade or an indoor break around midday, and carry water. Light, loose clothing makes more sense than a wardrobe built around layers. Evenings offer relief from the daytime peak, but average lows of 22.6°C mean they are still warm rather than crisp. If heat disrupts your sleep, prioritise accommodation with air conditioning. August is a less comfortable choice if you prefer staying active outdoors throughout the day.
Warm swimming water, plenty of sun and occasional rain
The sea is comfortably warm for swimming at 26.5°C, making August a good fit if getting in the water matters more than keeping cool on land. Expect about 10 hours of sunshine within 13.5 hours of daylight, giving you flexibility to swim or spend time outside away from the strongest midday heat. Sunscreen, sunglasses and a hat deserve space in your bag. Rain need not dominate your plans: there are about 3 rainy days during the month. That still leaves scope for a wet spell, so keep your daily plans flexible rather than assuming every afternoon will be dry. A light waterproof is a sensible precaution, not the focus of your packing.
