There are also seasons to consider.
Kunming has a long wet rainy season, from June until Oct-Nov. The last two years the season has come earlier and gone out later. It often rains everyday and can be very cool as you get higher and further north in Yunnan. Not ideal climbing weather.
The winter is cool and dry, but maybe not too good for making your shoes sticky.
The rainy season also falls during the school holidays, if you are a teacher this would be your main climbing season.
Check out the seasonal weather in Guilin as well, before you make a choice.
