We are going to Spain Next Monday, Sept.11. We land in Malaga and will spend a few days in Costa del Sol and then move on to Sevilla and Granada. Can anyone tell me if there is any chance I would need a jacket this time of year? I'm thinking no, but its gotten cool here, in Kansas City, and that usually doesn't happen this early, so I would like to know if the same's happening there. I would love it.

spain is a very mountainous country, therfore it can cool down in the evening to where a light jacket would feel welcome, even in spetember.

also, if you go out on a boat, the wind can be chilling.

right now i would say take one although you probably wont need it.

You don't need one. The temperature at this moment is in Celsius:

Sevilla 24 to 40(inland)
Granada 15 to 37 (in the mountains)
Malaga 19 to 29 (on the coast)

Right now you don't need it..but we hope it changes soon, the temperatures are too high for September

We were in Andalusia at that time last year and we needed a sweater/jacket in the evening.

The daytime was warm in Seville, even downright hot, but the evening cooled down. In Granada, we visited the Alhambra from 8:00 a.m. until 1:00 p.m. and I wore my sweater until 11:00 a.m. It warmed up in the afternoon, but cooled down again at night.

I am in Barcelona right now and it is really hot and humid, but in Alicante last week I needed a light jacket on two occasions. I would definitely take one, not just for the possibly chilly nights, but for the plane there and back.

Oh, and according to my teacher, temps will drop tomorrow.
