Chengdu - Post Report Question and Answers
What is the overall climate: is it extremely hot or cold, wet or dry, at any time of year, for example?
Mild winters with some very hot summer days. Some rain but not for days at a time. - Aug 2017
Aside from the pollution, Chengdu is a generally cloudy place. It is often overcast, and sunny days are rare. It is generally very humid in the city, so summers are brutal, and winters are damp and clammy. - May 2016
Temperature-wise, Chengdu is very similar to Washington D.C. Summers can get quite hot and humid in the mid 80's to low 90's. Winters are damp and chilly but the temperature rarely drops much below freezing. Spring and Fall are really quite pleasant, temperature-wise. If it weren't for Chengdu's nearly perpetual cloud clover, the climate would be pretty fantastic. The lack of sun, compounded by the pollution, really gets to some people. Interestingly enough, Chengdu residents swear that the city has gotten sunnier since the big earthquake in 2008. I don't know for sure whether this is true but our second year was most sunnier than the first so perhaps the pattern simply changes year to year. - Aug 2013
Early spring, super-humid summer, long fall and a short, but painfully dreary (but not that cold) winter. - May 2013
