The strongest months for visiting Nanjing are April, May, September, and October. April brings a high near 23.4C with 7.8 hours of sunshine a day, May climbs to a high of 26.5C with 8.2 hours of sunshine, and October offers a milder high of 22.6C with lower rainfall of 66mm compared with the wetter months around it.
The trade-off is that this same window is the peak season, so travelers share the mild weather with more visitors. September, despite a good visit score, brings heavy rain at 219mm, and summer months such as July and August push highs to 33.0C and 33.1C with substantial humidity, which is part of why those two months fall into the off-season instead.
