Seville - Spring versus Winter

Just the obvious ones--smaller crowds in February, but short days and who knows weather (I'd look at Wunderground for stats). April you can have higher prices, crowds around Easter. People generally advise skipping summer/early fall because of the oppressive heat, but I would not hesitate to go in spring. If I got offered a trip in February, I'd take it for the opportunity to do a deep dive without crowds, but April would be close to ideal for seeing the city as its best.

How large are the crowds around Easter? My husband works for a school, so we are tied to that calendar which puts his time off at Easter and the week after.

The crowds Easter week are huge, but the festivities make up for the crowds. Hotel prices are also more expensive. For a more relaxed visit, I’d say go in February when there are fewer tourists and prices are lower. It will also be cooler in February, but that shouldn’t be an issue.

But how cool would it be to see the Easter processions and festivities. That would be my choice despite the crowds.

Looked it up. It appears that Holy Week is April 2nd thru April 9th. We'd be there April 8th thru April 15th. So perhaps good timing to catch the very end of the festivals. And then perhaps less crowds afterwards?

April the citrus trees are in bloom and the odor is one in a million, worth the price of a ticket alone. J

If you're arriving on Saturday, most of the festivities are over, you may catch a procession or two in the afternoon. The streets around the cathedral will still be closed to all traffic, others will be open except if there's a procession scheduled for them, so it shouldn't be too difficult to get to your hotel. I think there's a final procession on Sunday morning. Some of the brotherhoods and churches will be open those 2 days so you can get a close-up look at the elaborate and beautiful thrones. Monday is clean-up day, partly the debris but mostly getting the layers of wax off the streets. You'll probably pay high high season prices at least at the beginning of your stay.

I've been to Sevilla a couple of times in February. The weather was sunny and pleasantly warm (Andalucia is the warmest, driest part of Europe) - warm enough to enjoy cold drinks while sitting in the sun. Hotel prices are low season and there aren't so many tourists that there are long lines at any of the sights.

I paid 225% more for the same hotel for Semana Santa as I did the previous year in February.
