Shanghai taught me that 'shoulder season' is everything here. I arrived in early June thinking it was safe — landed straight into plum rain season, three solid weeks of 28°C and 95% humidity. Pack quick-dry everything June mid-July. The real sweet spots are April-May (20°C, low rain) and October (22°C, clear skies). Skip August — typhoon season plus 33°C plus 85% humidity is brutal. Winters (December-February) are damp and cold in a way the thermometer doesn't capture; 4°C feels like -2°C with the wet chill. Bring a down jacket.
