wheather in Samoa - now

this is again me, can anyone who is already in Samoa tell me what the wheather there is like?

maybe stupid question, but last time when i traveled to Fiji i brought a few warmer clothes that I had not had to take with me, and which i eventualy left in a hostel. This time i wanna do some middle-range hiking. Is it necessary to bring such stuff as trousers, light jumper and even a jacket?

Period september-october

thank you

Samoa is warm year-round and I only rarely need anything more than a t-shirt around here. A rain jacket is all you'd need. If you're hiking through the bush, take some trousers, but they're not necessary if you're sticking to existing trails. I always take a small (as in very compact) sweater with me when I travel, because I get cold on big planes.
