When you look at that graph, and, indeed, today's, you'll notice that the peak moments coincide with low wind speeds. Winds are very strong in spring afternoons and I believe they blow a lot of the pollution away. When the wind dies down at night, the air fills up with pollution again. From diesel trucks, certainly, but construction, too. And agricultural stalk burning.
What puzzles me is that the humidity, which reaches 100% at night, doesn't precipitate the pollution. I thought it should?
Anyway, high AQI rates are common for Kunming in spring. But that doesn't mean it isn't utterly disgusting. We should all be aware that we're slowly being killed here.

Posted byChangkt: given the extreme variation in climate along the river, it's hard to say. We ourselves asked around before going and learned that October is the best month to go, but when we were in the northern end (you'll have to wait for part two), we learned from locals that May is a lot better.
I think they may be right about that: after all, the more interesting part is the northern trail and warmer temperatures and less rain would've been nice. The southern part may be very hot by then, but I guess that still beats rain and cold.
