When to go, and when not to
April, May, June, and September stand out as the best months to visit Chengdu based on three years of visit-score data. April and May bring warm highs of 25.0C and 28.4C alongside 6.4 and 6.3 hours of daily sunshine, while September offers a high of 28.5C, making these months a comfortable stretch for outdoor plans.
The trade-off is that April through September also forms the peak season, when travel is busiest. July and August are the hottest and wettest months, with July recording 265mm of rain and August reaching a high of 32.1C, so travelers sensitive to heat or heavy rain may prefer April, May, or the drier days of September instead.
