Warm days, with a chance of stronger heat
The average temperature makes July sound comfortable, but hotter spells are the main catch. Days reach 30°C on 16% of occasions, so allow for sightseeing to feel tiring in direct sun. Keep longer walks for the cooler parts of the day and leave yourself the option of a shaded or indoor break around midday. Light, breathable clothing is the sensible starting point, and accommodation with cooling is worth considering if heat affects your sleep. Evenings are generally much cooler than afternoons, though the coldest nights can fall to 13°C or below. A light jumper gives you more flexibility than packing only for hot weather.
Plan for rain without giving up outdoor time
July is warm, but it is not a reliably dry choice. About 12 days have measurable rain, which makes a compact umbrella or light waterproof useful rather than unnecessary luggage. That figure does not tell you how long rain will last, so keep outdoor plans movable instead of assuming a wet forecast means losing the day. The long daylight hours leave room to change your schedule, while regular sunshine makes outdoor time appealing between wetter periods. This month suits travellers who can mix walking with indoor breaks. If your priority is a trip with little need to think about rain, July's warmth comes with a clear compromise.
