Zhuhai, a coastal city on the western side of the Pearl River estuary in Guangdong province, sits on the South China Sea beside Macau in southern China at approximately 22.27°N, 113.58°E. Just south of the Tropic of Cancer, it has a humid subtropical climate (Köppen Cfa) verging on tropical — with long, hot, wet summers and short, mild winters — moderated and dampened by its exposed seaside position and exposed to typhoons.

Summer is long, hot and humid, running from around April to October, with July the warmest month — average highs around 32°C — tempered a little by sea breezes but heavy with humidity. This is the wet season, when the monsoon brings frequent downpours and thunderstorms, and Zhuhai's exposed coastal position places it directly in the path of typhoons from June to October, which bring torrential rain, strong winds and storm surge.

Winter, from December to February, is short and mild, with January the coolest month — average highs around 18–19°C and lows near 11–12°C, kept above frost by the surrounding sea. Brief cold snaps can bring cool, damp weather, but genuine cold is unknown, and the mild, sunnier, drier winter is comfortably the most pleasant time of year on the coast.

Zhuhai is very wet, receiving around 1,900–2,100 mm of rain a year, overwhelmingly concentrated in the wet season from April to September, when monsoon rains and typhoons deliver the heaviest falls; a single typhoon can drop enormous totals. Live rainfall, humidity, and pressure readings for the city are shown in the panels above.

Zhuhai's exposed position on the South China Sea, at the mouth of the Pearl River beside Macau, gives it a breezy, humid maritime climate and places it squarely in the path of the typhoons that strike Guangdong from June to October, the main weather hazard, bringing torrential rain, damaging winds and storm surge. Its seaside setting also gives it somewhat cleaner air and milder extremes than the inland delta cities.
