Best time to visit Shiyan: month-by-month weather (2026)

April, May and June are the best months to visit Shiyan, combining moderate high temperatures, in the mid-20s to low 30s Celsius, with some of the highest sunshine totals of the year and comparatively moderate rainfall. These conditions make the spring into early summer stretch the most reliable window for outdoor sightseeing.

The trade-off comes later in the peak season, which runs from April through August: July and August bring the highest temperatures of the year, at 33.0C and 32.9C respectively, along with heavier rain, with July recording 188mm and September following close behind at 175mm. Visitors who prefer drier, cooler conditions and lower prices can instead consider the off-season months of January, February and December, accepting cooler temperatures and less sunshine in exchange for quieter travel.
