hi
i cycled from kunming to diqing in january of i think it was 2002 anyway it was cold but the only snow i encounterd was on the north side so mountain passes where the sun never got to. the sky was always clear and blue and the views were fantastic which is often not the case in july when the main tourist time is. when i reached diqing i turned around and came back down in altitude and of course it was warmer. the north of the country was having a particualy bad winter from what i could make out of the tv news but yunnan was fine for me then.
hope this helps
Flid
