Chile, South America
gubbe asks,
“What's the best time of year to visit Chile with a bicycle? It would need to be at least 17-18 degrees Celsius minimum.”
I think spring (Sept-Nov) and fall (March-May) are the best times to see Chile by bicycle. The summer, though dry, can be too hot, especially up north (though I had a very successful January camping trip in the south). And the winter is too rainy. In poarticular, September is one of my favorite months. Not only would you be there for Fiestas Patrias, but the weather is just particularly nice.
