マカオ 9月の天気

Regulars quantify the typhoon risk rather than leaving it vague: the chance of one hitting during a specific one-week stay is under 10 percent, even though this month sits inside the peak August-September window for the strongest, signal-8 storms that shut down ferries, schools and casinos. Our row backs the wet, humid reality behind that risk, a striking 286.5mm of rain across 20.3 days, alongside intense heat, 31.5C reading as a hot 37C at 84 percent humidity, over 25.5C nights. Regulars are candid the year-to-year swing is real - some years bring three signal-8 closures in a season, others none at all - with one regular's most recent September described as warm and clear skies on most days despite sitting in typhoon season. The sea holds a very warm 29.8C. The record: 9.3 hours of sun, a 16.7 kph wind and AQI 78.

Mid-October to December is the comfortable stretch here and November is its best month: around 20C by the board's reckoning, our row a little warmer at 25.4C by day over 19.4C nights, with short sleeves at midday and a long sleeve after dark. Rain has dropped to 45.3mm across 6.3 days. The complication is the race. Grand Prix week closes streets across the peninsula, reroutes the buses and the hotel shuttles, and lifts room rates - while Cotai and Taipa carry on as normal, which is the practical answer if you are not here for it. The record: humidity 75 percent, 8.1 hours of sun, a 24.2C sea and AQI 89.

March here sits between the cold snaps and the rains: not hot yet, mostly past the chill, and the wet season still to come. Our row gives 22.4C reading as 24C over 17C nights with 69.4mm across 10.3 days. What regulars warn about is fog. Spring is the grey season, humidity starts climbing from late March - ours already reads 83 percent with a 17.1C dew point - and the view from the tower can simply be gone. They call March the year's least sunny month; our column puts it third at 7.8 hours, behind January and February, so the pattern is right and the ranking is not. A 19.9 kph wind makes a long walk cold. The record: a 21.5C sea and AQI 93.

A Hong Kong-forum thread planning a joint Hong Kong/Macau December trip lands on a Macau-specific rhythm: mornings are for the steep peninsula heritage climbs - Guia Hill, Monte Fort - while the cool afternoons suit the flat Cotai and Taipa side, timed so the light shows are running by evening. The advice is to skip Senado Square in the day and come back after 8pm once the festive lights are up and the tour buses have gone. December runs cooler than visitors expect, with harbour wind cutting through by evening. The record: 20.6C days feeling like 19C, 14.3C nights, 15mm total across 2.5 days and eight hours of sun. The gap between forum chat and the data: AQI sits at 111 here, hazier than the pleasant temperatures suggest.

Macau forum threads consistently rate late winter into February as one of the better windows here - generally mild, above 10C most days though it can dip below 5C at times, and notably dry thanks to the Siberian High keeping moisture away this time of year. Posters described this as the season locals themselves prefer for spending long hours outdoors, a real contrast to the heat, humidity and frequent rain of Macau's summer months. The practical caveat repeated across threads: a sweater and a proper jacket are genuinely necessary, and wind can make it feel colder still on an exposed walk, so it's not shorts-and-t-shirt weather despite the relatively mild average.
