Warm rather than constantly scorching
Costa Adeje's average July high is 4.5°C above London's, so the difference should feel clear without every afternoon being fiercely hot. Days reach 30°C on 12% of occasions, meaning hotter spells are possible but are not the everyday pattern. Light, breathable clothing makes sense, with walking better planned for earlier or later in the day if you dislike heat. Keep lunchtime flexible so you can choose shade rather than push through an exposed outing. July is among the warmest months here, so it is a strong choice for warmth, but less suitable if cooler days are central to your holiday.
Dry days and a sea warm enough for swimming
Rain is unlikely to dictate your plans in July, making outdoor days a sensible basis for the trip rather than a gamble on clear weather. There are about 12.2 hours of sunshine within 13.6 hours of daylight, so shade, sunscreen and something to cover your shoulders deserve space in your packing. The sea averages 22.1°C, warm enough for swimming, though it may still feel fresh as you get in. Its July range of 21°C to 23°C means the water is not equally warm every year. If you prefer lingering in very warm water, keep that modest sea temperature in mind.
