Here we only have summer-winter in Ecuador, but it's not that different, so even with summer clothes you will live through the winter, of course wet and cold but it won't kill you :b we can wear the same clothes all year round, changing clothes, tastes, adaptations for each season must be tiring to do it every year I imagine.
It is similar in tropical Australia with "wet/ dry season. The wet is hotter and humid, the dry is still warm and sunny. Not a bad place to be homeless in comparison to Finland. At least in the tropics there are fruit trees and oysters! :D
