Climate Chart of Shanghai, China

Climate overview

Temperature

The monthly mean temperature is lowest in January, at 5.3 °C, and reaches its highest monthly mean in August, at 28.3 °C. These figures describe average temperatures for each month, not daytime maximum temperatures, so they should not be read as a daily forecast or as the full range visitors might experience. The unweighted mean of the monthly means is 16.9 °C; it summarizes the calendar-month figures rather than weighting them by the number of days in each month.

Rain

Mean daily rainfall reaches its highest monthly level in June, at 8.37 mm/day, and its lowest in December, at 1.38 mm/day. These daily averages help identify when rainfall amounts tend to be greater or lower, but they are not monthly totals and do not show how often rain falls or guarantee dry weather in the lower-average month. Across the monthly figures, the unweighted mean is 3.76 mm/day per day, a broad summary rather than a day-weighted annual average.

Sunshine

Average daily sunshine is highest in August, at 9.58 hours/day, and lowest in February, at 5.73 hours/day. This can help with planning outdoor sightseeing around typical sunshine duration, although it is not a measure of day length and does not guarantee clear skies on any particular day. The unweighted mean across the monthly sunshine figures is 7.17 hours/day per day, offering an overall reference without implying the same conditions in every month.

Snow

Recorded mean daily snowfall is highest in February, at 0.99 mm/day; the unweighted mean across the monthly figures is 0.18 mm/day per day. These are averages of daily snowfall amounts, not monthly totals. They do not indicate how many days have snow, whether snow accumulates or remains on the ground, or whether conditions support skiing.
