Rain in China is seasonal and regional, not a constant national drizzle. The East Asian summer monsoon concentrates much of the year's moisture in the warmer months. CMA (China Meteorological Administration, the national weather service) tracks the South China Sea summer monsoon onset as a signal that the main flood season is underway across large parts of the country.
Where is rain heaviest, and when does it concentrate?
Southeast China, including Guangdong, Fujian and much of the coastal south, sits on the wetter side of the monsoon belt. Summers bring frequent rain spells, and typhoon tracks can add intense coastal downpours from midsummer into autumn. Shenzhen and Guangzhou need drainage checks and commute plans for flooded underpasses, not only umbrellas. See living in Shenzhen and typhoon risk in China.
Shanghai and the lower Yangtze often face meiyu (plum rain) in early summer: grey, humid days that keep laundry damp and streets slick. Later summer convection and occasional coastal storm rain still matter. Beijing gets summer thunderstorms and monsoon rain too, but winters are comparatively dry. That dry-cold vs damp-cool contrast is one reason Shanghai vs Beijing feels different beyond temperature.
Northwest inland areas and desert-adjacent basins are the opposite story: arid air and low totals that feel nothing like Hong Kong, Guangdong or the Yangtze valley. Chengdu sits in a humid basin where cloudy, damp spells are part of daily life even when a single storm is not dramatic.
What should renters check on a rainy address?
Look at floor level, basement flood history, balcony drainage and whether the building entrance sits in a low street that ponds after a cloudburst. In Shanghai and Shenzhen, ask how elevators and ground-floor shops behave in heavy rain. In Beijing, summer storms can still disrupt roads even though winter precipitation is light.
Outdoor plans should stay flexible: parks and Great Wall day trips from Beijing, water-town weekends from Shanghai, and Sichuan mountain access from Chengdu all depend on the day's rain and visibility.

Common misconceptions
China is not "always raining." Much of the reputation comes from summer monsoon concentration and meiyu weeks, not from twelve wet months everywhere. A dry Beijing winter also does not mean North China skips heavy summer rain or local flooding.
Summary
Expect China's rain to pile into the warm monsoon season, hit the southeast and lower Yangtze hardest, leave the northwest relatively dry, and intensify near the coast when typhoons or tropical systems arrive. Judge the home by drainage, floor level and commute under water, not by a single national "rainy country" label.
