HotWeather in Ibiza in July
July is a good time for Ibiza if you want hot, dry weather and a sea that feels comfortable for swimming. Average daytime highs reach 30.6°C, nights stay around 22.5°C, and the sea averages 25.2°C.

For a UK traveller, it suits a swimming-led holiday better than a packed schedule outdoors.

Expect heat that shapes your day
July is among Ibiza's warmest months, so plan around the heat rather than expecting an occasional hot afternoon. Temperatures reach 30°C on 64% of days, making shade and breaks useful parts of a daily routine. Put more active plans in the morning and leave the middle of the day for a slower pace, with drinking water close at hand. Light, loose clothing is more useful than heavy layers, while warm nights make accommodation with cooling a sensible priority if you struggle to sleep in heat. This is a strong choice for heat lovers, but less comfortable for travellers who prefer being active outside throughout the day.
Plenty of sunshine, little need to plan around rain
With about 12.3 h of sunshine a day, July gives you plenty of scope for outdoor plans without squeezing everything into midday. Rain is unlikely to be the main disruption: there are about 0 rainy days on average, though that is not a promise of an entirely rain-free stay. Sun protection deserves more space in your packing than wet-weather clothing. The long daylight also lets you leave some outdoor time until later, when you can avoid the strongest sunshine. Warm seawater makes swimming an appealing focus, but do not expect it to feel particularly cold or provide a lasting break from the heat.
