At this picture you see that we are lucky. Today we have the highest temperature of the last 2000 years and it's still increasing.
In orienteering we have a lot of Scandinavian runners. They are not able to do much orienteering in winter time unless they go somewhere else. Not only scandinavian runners go to the south... everybody does. They go everywhere to find a place for a good training camp: Portugal, Spain, South-Africa, Australia, Lanzarotte, ...
But as we experienced in Portugal, this expected "good weather"is not always there when you want it. So I wanted to figure out what is the place with the best chances of nice weather, not to hot, not to cold, no rain, ...
This website helped me a bit. For each place you can find information about temperature and rain, sometimes more.
Climate is a very subjective thing, whether a climate is best or worst all depends on what you like. you could say Southern California has the best climate, because of all the sunshine and low humidity, but on the other hand you can never go skiing because there's no snow.
A few places clame to have "the best climate in the world" but with the climate change this might change as well. I found following places:
Atenas - Costa Rica
Atlixco - Mexico
The Canary Islands
Faulconbridge - Australia
Redwood City - California
