April 4th in Kunshan sits right in the middle of spring's transition, with an average high of 63° and low of 46° across 66 years of records.

Kunshan's climate has real teeth at both extremes — the mercury has hit 105° in the brutal summer of 2013 and plunged to 10° in February 1969. Rainfall can be intense: a single day in June 1983 dropped 6.16 inches, and a January 1984 snowstorm buried the city under 9.6 inches.
Kunshan follows a classic humid subtropical pattern — summers are hot and wet, winters are cool and dry. The peak of summer runs mid-July through late August with average highs near 90°, while mid-January is the coldest stretch at just 46°. If you're trying to avoid rain, steer clear of late June and early July, when weekly precipitation averages top 3 inches.
