Welcome Jorge;
I live in California so our weather is similar but with opposite seasons. I love it here.
In the past I've mainly collected U.S. But a month or so ago I picked up a few albums with South American stamps. For the past few weeks I've been working on Chile.
Up here besides the regular auction houses I believe the best places to buy stamps are
ebay and bidstart. And of course my own stamp club. How about in Chile?
