Climate Chart of Hangzhou, China

Climate overview

Temperature

The monthly mean temperature is coolest in January, at 5.4 °C; this is a monthly average, not a daytime high. At the warm end, August has the highest monthly mean, 28.9 °C. The unweighted mean across monthly means is 17.4 °C, a broad summary that does not describe every month or daily temperature range.

Rain

Mean daily rainfall reaches its monthly high in June, at 11.90 mm/day, while the lowest monthly mean is 1.69 mm/day in December. These are daily averages, not monthly totals, and the lower figure does not indicate how many days are dry. The unweighted mean of the monthly means is 4.31 mm/day; it gives an overall reference without describing rainfall on a particular day.

Sunshine

Average daily sunshine is highest in August, at 9.42 hours/day, and lowest in February, at 5.25 hours/day. The unweighted mean across the monthly means is 6.91 hours/day hours per day. These figures describe average sunshine duration, not daylight length, and cannot guarantee how much sun a visitor will get on an individual day.

Snow

The highest monthly mean for daily snowfall occurs in January, at 2.05 mm/day. The unweighted mean across monthly means is 0.45 mm/day. These amounts do not establish how many days have snow, snow depth or snow cover, so they cannot by themselves indicate whether snow-related activities will be possible.
