Expect proper heat, not just pleasantly warm days

July's average high hides some hotter spells: 65% of days reach 30°C, while the hottest days can reach 34°C or more. That makes Hammamet a better fit for a relaxed swimming holiday than for long periods of activity in the midday sun. Humidity averages 66%, so do not assume the dry weather will always feel like dry heat. Choose loose, breathable clothing and accommodation with air conditioning if warm nights affect your sleep. Evenings offer some relief from daytime temperatures, but they are still warm rather than crisp. Keep water handy and leave room in your plans for shade and breaks.

Warm swimming water and little rain to plan around

The sea averages 25.2°C, with a year-to-year range of 24°C to 26°C, making July a sound choice if swimming is central to your holiday. Rain is unlikely to disrupt outdoor plans, though dry conditions are not an absolute guarantee. Sunshine averages about 12.9 hours out of 14.2 hours of daylight, giving you plenty of scope to spend time outside without relying on the hottest part of the day. The catch is prolonged sun exposure: sunscreen, a hat and regular shade matter more than packing for wet weather. Use the cooler ends of the day for activity and take a shaded break around midday.
