Expect proper summer heat, not just warm afternoons
Pack for hot weather and plan your more active time for the morning or later in the day. Temperatures reach 30°C on 38% of days, so hotter afternoons are a regular possibility rather than an exception. Humidity averages 69%, which can make the warmth feel less comfortable, particularly when you are moving about. Loose, breathable clothes, shade breaks and accommodation with air conditioning are sensible priorities if you struggle with heat. August suits travellers who want to spend plenty of time swimming or relaxing; it is less appealing if your ideal holiday involves long walks through the middle of the day.
Plenty of sunshine, with room for a wet-weather plan
Salou averages about 8.7 hours of sunshine a day in August, leaving plenty of scope for time outdoors without needing to spend the hottest part of the afternoon in direct sun. Rain is still part of the picture, with about 7 rainy days during the month. That is enough to justify keeping plans flexible, but it does not mean those days are wet throughout. Bring a light waterproof layer alongside your swimwear and sun protection. If you need completely dry weather to enjoy the trip, August carries a catch; if you can adjust your plans when rain arrives, the overall balance remains favourable for a summer holiday.
