Warm days, but pack for cooler evenings
Light clothing should work well during the day, with a jumper or jacket ready for after dark. Days reach 25°C on 64% of occasions, so October suits travellers who want warmth rather than guaranteed intense heat. That said, the hottest days can reach around 32°C or more, making exposed midday walks less comfortable. Keep longer walks flexible and take breaks in the shade when it feels hot. At the other end, the coldest nights can drop to around 9°C or below. If you plan to stay out late, bring trousers and a proper extra layer rather than assuming daytime warmth will last.
Plenty of sunshine, little rain
With about 8.6 hours of sunshine out of 11 hours of daylight, October gives you plenty of scope for outdoor plans. Rain is unlikely to dominate the trip, so a heavy waterproof need not be the focus of your packing, though dry conditions are not a guarantee for every day. Sun protection is more useful as an everyday habit: take sunglasses, use sunscreen and carry water when walking. Humidity averages 28%, so expect a dry feel rather than muggy conditions; lip balm and moisturiser may be welcome. Make use of the daylight for outdoor time, then have warmer clothing available as the temperature falls.
