HotWeather in Seville in September
September is a good time for Seville if you want hot weather, but it is not a mild autumn city break. Average daytime highs are around 30°C, with night-time lows near 19°C and about 8.4 hours of sunshine a day. That suits travellers happy to slow down in the afternoon and spend time outdoors later.

Plan for heat, not autumn cool
Pack as you would for summer rather than a typical September at home. Days reach 30°C on 59% of occasions, while the hottest 10% reach around 35°C or more, so the average does not tell the whole story. Put your more active plans in the morning and leave room for shade, indoor breaks and a slower pace around midday and through the afternoon. Loose, lightweight clothes, sun protection and water are sensible essentials. September suits you if warmth is part of the appeal; if you prefer walking all day without thinking about the heat, it is a less comfortable fit.
Rain needs a backup plan, not a change of plans
With about 4 rainy days in September, rain is a possibility rather than the main constraint on your trip. You can reasonably plan time outdoors, but keep some flexibility instead of assuming every day will stay dry. A compact umbrella or light waterproof is a practical addition to your bag; heavy rainwear need not dominate your packing. The sunshine makes shade useful even when your plans are fairly relaxed. For clothing, prioritise breathable daytime outfits and add a light layer for later, rather than bringing an autumn wardrobe built around cool, grey weather. Check the forecast before leaving to adjust that balance.
