A wave of cool weather has swept across Guangdong province, resulting in temperatures noticeably dipping across most of the region’s cities and counties on 9 November 2026. The drop was especially pronounced in the province’s north-central parts, where the mercury plummeted by 7°C to 11°C overnight, according to Guangdong Meteorological Observatory data cited by Nanfang Daily.
As the cold wave continues to impact Guangdong, local meteorologists expect the average temperature to continue falling slightly on 10 November, with the lowest temperatures of this spell expected by the morning of 11 November.
The minimum morning readings in northern Guangdong and the northern part of the Pearl River Delta are forecast to hit a low of 8°C to 10°C during this period. Meanwhile, coastal areas in the south can expect morning temperatures ranging between 14°C and 16°C.
Looking to 11 November, Guangdong’s daytime temperature is projected to rise. Cities and counties to the south can expect to see a maximum temperature hovering between 23°C and 25°C, while most other areas in Guangdong will have readings between 19°C and 22°C.
By 12 November, the daytime maximum temperature around northern Guangdong will reach between 22°C and 25°C, with most other parts of the province expected to record a reading ranging from 25°C to 27°C.
Temperatures fall in Guangzhou and Shenzhen
Across the Greater Bay Area (GBA), various cities have seen their temperatures drop sharply. On 9 November, the reading at Guangzhou’s Wushan observatory plummeted to between 20.5°C and 23.9°C – a far cry from the roughly 30°C maximum reading recorded a day earlier.
Temperatures in Guangzhou are set to remain relatively cool on 10 November, hovering between 14°C and 22°C. The following day, the provincial capital is forecast to register temperatures between 13°C and 24°C, followed by readings between 15°C and 26°C on 12 November.
The Guangdong cold wave has also impacted Shenzhen, where the local observatory issued a blue strong monsoon alert on 9 November. Temperatures in the tech hub are forecast to drop to between 15°C and 23°C on 10 November. The local forecaster is anticipating a rise in the mercury in the coming days, with readings of 16°C to 24°C on 11 November, as well as 19°C to 27°C on 12 November.
How has the Guangdong cold wave impacted Hong Kong and Macao?
Hong Kong recorded a minimum temperature of 17.5°C on 10 November (6:30 am), the city’s lowest reading to date since the start of autumn.
In a TVB report broadcast on 10 November, Hong Kong Observatory scientific officer Leung Lai-lai noted that temperatures across Hong Kong’s various districts hovered around 16°C to 17°C that morning, an average drop of around 7°C when compared to the same time a day earlier.

“The northeast monsoon will bring generally fine and dry weather to Guangdong in the next couple of days,” the observatory noted in a forecast last updated on 10 November (11:30 am). It added that “temperatures will rise in the latter part of this week.”
Macao is also facing cool weather as a result of the northeast monsoon. The local forecaster’s Taipa Grande measuring station logged a minimum temperature of 16.1°C on the morning of 10 November, down by approximately 6°C when measured against the figure from a day earlier. The current reading also marks the lowest temperature recorded in Macao so far since the start of autumn 2026, according to TDM.
Looking ahead, the Macao weather bureau is predicting cool weather on 11 and 12 November, followed by warmer temperatures towards the end of the week.
