Warm days, with little cooling after dark

Sal's average daytime high is 24.7°C in July, compared with London's 21.8°C. That is a noticeable step up, rather than a dramatic jump into extreme heat. Days reach 25°C around 30% of the time, so do not assume every afternoon will feel hot. Humidity is high at 82%, however, which can make the warmth feel more persistent. Pack loose, breathable clothing and keep your plans flexible if midday feels uncomfortable. The average night low of 23.3°C means evenings offer little cooling, so light evening clothes are more useful than a wardrobe built around chilly nights. Accommodation with cooling is a sensible preference if you sleep badly in warmth.

Rain is unlikely to shape your plans

July is very dry, with about 0 rainy days and just 2.0 mm of rain across the month on average. That makes it a sensible choice if avoiding wet-weather disruption matters more to you than chasing the highest temperatures. It is not a guarantee of completely rain-free weather, but there is little reason to organise your holiday around indoor alternatives. Sunshine averages about 7.1 hours within 12.9 hours of daylight, so expect useful sunshine rather than assume clear skies throughout the day. Take sun protection and comfortable daytime clothing, while leaving room in your expectations for periods without direct sun.

A good fit for swimming, not extreme heat

The sea averages 24.1°C in July, with a year-to-year range of 24°C to 25°C. That puts it comfortably in swimming territory on temperature, rather than making a dip something to endure. If your ideal holiday involves time in the water followed by warm afternoons, July fits well. The main trade-off is that Sal is warm rather than fiercely hot: even the warmest 10% of days reach 27°C or more, which gives a better sense of the usual upper end than expecting scorching weather. Choose July for its combination of swimmable sea and very little rain, not because you want the hottest possible summer destination.
