I have some friends living in the Canary islands and I always envy them when they tell me the weather is pretty warm all year long so they basically have only summertime clothing :)
The problem comes whenever they have to travel to any Spanish city in the peninsula during the winter and they freeze!!!!
I lived in the topics of Australia for 8 years - It isn't bad! :D
One of my brothers lives there still and once when I was visiting many years ago in the south and they met us - my girlfriend and I were swimmin in +32 temperatures and he was wrapped in a blanket sitting on the beach - and he was once a surfer in the south! :D
It is all about conditioning.
