Expect heat that shapes your day

Andalucia is noticeably hotter than London in July, with average daytime highs 7.8°C higher. This is not just occasional hot-weather territory: 40% of days reach 30°C, and the hottest days can make sustained activity uncomfortable. Plan anything energetic for the morning, leave room for shade or an indoor break around midday, and avoid an itinerary that depends on walking all afternoon. Loose, light clothing is a sensible starting point. With average night lows of 20.9°C, evenings are warm rather than reliably cooling, so check that your accommodation has cooling if you struggle to sleep in heat.

Rain is unlikely to disrupt plans

July suits travellers who want to make outdoor plans without much concern about rain. There are about 0 rainy days on average, so waterproof clothing is a lower packing priority than sun protection. That does not mean rain is impossible, but it is unlikely to be the main weather issue during a stay. Sunshine averages about 12.8 hours a day, giving you plenty of scope to move activities away from midday rather than trying to fit everything into the hottest part of the day. Pack sunscreen, sunglasses and a hat, and build shade and drinking breaks into your plans.

The sea is cooler than the air suggests

Do not assume hot afternoons mean a warm sea. July's average sea temperature is 21.7°C, which falls in the bracing category and may feel sharp when you first get in. The year-to-year range is 21°C to 23°C, so your experience can vary from the average. This suits travellers who enjoy a cooling dip more than those who want to linger in reliably warm water. If swimming is central to your holiday, keep that distinction in mind when deciding. For time beside the sea, the bigger practical concern remains the sunshine: take shade breaks rather than staying exposed throughout the afternoon.
