Seville (Sevilla) weather in September

Regulars agree August's extreme heat has eased by this point, though days can still spike into the high 30s Celsius even as the overall average runs cooler than that peak. Our row backs the still-hot-by-day read, 32.3C reading as a firm 33C, over 18.5C nights, with rain almost absent at 15.8mm across just 2 days. Regulars describe genuinely pleasant evenings once night temperatures start dropping, with dinner around 9-10pm - standard Seville timing - now comfortable rather than sweltering, and mornings pleasantly cool in the low 20s before the day's heat builds. That evening warmth is treated as a plus by regulars for terrace dining and dawdling outdoors, not just a downside to endure. The record: humidity 55 percent, 11 hours of sun, a 13.5 kph wind and AQI 37.

The question this board answers most often in March is when the orange blossom comes, and the answer is conditional: usually the end of February into early March, earlier after a warm February and into mid-March or later after a cold one. There is no date to book against, only the year's weather. March itself is pleasant rather than warm - our row gives 20.9C reading as 19C over 9.1C nights, with 86.6mm of rain across 9 days, so a sweater and an umbrella. Holy Week moves with Easter and can land in March or April; when it does, the city fills completely. Check the year before booking. The record: humidity 68 percent, 9.5 hours of sun and AQI 37.

Regulars describe February here as the month spring begins while the rest of Europe is still in winter: blue skies, green trees, no need for winter clothing by day. The qualification is the hour - it is genuinely chilly at night and through the morning until the sun takes hold around eleven - and our row's 19.3C high over a 7.6C night that feels like 5C is that gap. Rain is unlikely but not gentle when it comes: 30.6mm across 3.4 days means when it rains, it rains. They also note the city is calmer now than in spring, though never actually quiet. The record: humidity 71 percent, 8.6 hours of sun, a 14.1 kph wind and AQI 38.

Seville-forum threads on May split into two camps: one calls it a really nice month, warm without yet being too hot, the other flags mid-May specifically as capable of running properly hot, high 20s into the low 30s Celsius - both agree it's still short of the scorching months to come. When Easter's date pushes the Feria de Abril into early May, the whole city runs in festival mode for the week, worth checking before booking either way. The standing tactic either way: sightsee in the morning and evening, and treat the afternoon as siesta time rather than fight it. The record: 29.2C days feeling like 30C, 14.7C nights, just 33mm total across 3.9 days, 12.3 hours of sun and humidity a dry 56 percent.

Seville forum threads describe January as genuinely pleasant by day, with posters citing typical highs reaching well into the teens Celsius when the sun is out, but temperatures drop fast after sunset - down to around 5C late in the evening. Rain is possible but was described as usually light showers rather than sustained downpours. Posters were consistent that January and the wider winter stretch is the ideal time to visit precisely because of the crowd relief - all the major sights stay open with noticeably smaller crowds than the unbearable heat of the May-through-October stretch, though never genuinely empty. The standard packing advice was real layers: a sweater and coat for evenings even on a warm-feeling afternoon.
