How we pick the best months

  • Best: an average temperature of 15–28°C and low rainfall for Zhengzhou: under 150 mm, and no more than 60 mm, a quarter above Zhengzhou's median month (never set below 60 mm).
  • If no month qualifies, we show the three driest months that average 10–30°C instead.
  • Wet: 150 mm of rain or more. Rainy: more than 60 mm. Hot: 29°C or more on average. Cool: under 15°C. Cold: under 5°C.

Averages cover day and night, so afternoons are warmer than the figure shown. Weather is only one reason to pick a month: school holidays, festivals and prices matter too.
