Expect heat to shape your day

The main catch is sustained heat, not just the occasional hot afternoon: 57% of July days reach 30°C. The hottest days can push towards 34°C or beyond, making a packed outdoor schedule uncomfortable, especially if you struggle in hot weather. Plan your more active time for the morning, take a shaded or indoor break around midday, and keep the afternoon flexible. Lightweight, breathable clothes, a hat and water are sensible essentials. Nights are milder, but do not count on a cool bedroom simply because the sun has gone down. If warm nights disturb your sleep, prioritise accommodation with effective cooling.

Plenty of sunshine, with some room for rain

July brings about 12 hours of sunshine a day, so protecting yourself from the sun matters more than preparing for persistent wet weather. The long daylight gives you flexibility to move outdoor plans away from the strongest heat rather than trying to fit everything into midday. Rain is still possible, so keep an indoor alternative in mind and check the forecast before a long spell outside. A compact umbrella is a reasonable precaution, but heavy waterproof clothing is unlikely to be your most useful packing choice. This is a better fit for travellers comfortable with strong sunshine than those wanting mild conditions for walking throughout the day.
