Warm days, with little need for evening layers
Plan around the heat rather than assuming every afternoon will feel comfortable for a long walk. Days reach 30°C on 13% of occasions, while humidity of 74% can make the warmth feel sticky. Put more active plans in the morning, take breaks around midday and choose somewhere with air conditioning if warm bedrooms bother you. Lightweight, breathable clothes should do most of the work, with a light layer for cooler spells rather than heavy knitwear. Evenings generally suit eating outside without much extra clothing. August works best if you enjoy warmth, not if you need crisp nights to sleep well.
The sea is a strong reason to go
The sea is warm enough for swimming rather than just a quick cooling dip. Its average temperature makes August a sensible choice if cold water usually puts you off, and the year-to-year range of 24°C to 26°C suggests that this is not dependent on an unusually hot summer. Pack swimwear alongside your everyday summer clothes, and build in time by the water rather than filling every day with walking. Warm water does not tell you what waves or local conditions will be like, so judge those on the day. Sun protection still matters when swimming, particularly around the middle of the day.
Mostly outdoor weather, but keep plans flexible
With about 8.8 hours of sunshine across 13.8 hours of daylight, August gives you plenty of scope for outdoor plans without needing to use the hottest part of the afternoon. Rain is still part of the picture: about 6 rainy days means a completely dry stay is not something to count on. Bring a compact waterproof and keep some plans easy to rearrange, rather than packing as though every day will be cloudless. The balance favours a summer holiday outdoors, but a forecast check before committing to a full day outside is sensible. Sunshine averages are not a promise for your particular week.
