Climate Chart of Zhengzhou, China

Climate overview

Temperature

January has the lowest monthly mean temperature, at 1.7 °C; this describes the month’s average, not a typical daytime maximum or the temperature on any particular visit. At the warmer end, July records the highest monthly mean, 28.3 °C. The unweighted mean across the calendar months is 16.0 °C, a summary of monthly means rather than a day-weighted annual average. For planning, these figures help distinguish cooler-average from warmer-average months, but cannot specify day-to-day variation.

Rain

Mean daily rainfall is lowest in January, at 0.14 mm/day, and highest in July, at 4.65 mm/day. These are daily mean amounts for the named months, not monthly rainfall totals, and the lower figure does not guarantee rain-free days or reveal how often rain occurs. The unweighted mean of the monthly daily means is 1.70 mm/day. The contrast is useful when weighing average rainfall, while leaving individual-day conditions uncertain.

Sunshine

Mean daily sunshine duration reaches its highest monthly average in July, at 9.65 hours/day, and its lowest in November, at 6.49 hours/day. The unweighted mean across monthly averages is 8.08 hours/day. These figures can help with planning around average sunshine, but sunshine duration is not the same as daylight length and does not promise a particular amount of clear sky on a given day.

Snow

The highest monthly mean daily snowfall is recorded in February, at 1.95 mm/day, while the unweighted mean of the monthly daily means is 0.45 mm/day. These amounts describe mean daily snowfall, not monthly totals. They do not establish how many days receive snow, how deep it becomes, whether snow cover persists, or whether conditions suit skiing.
