Macau in May

The wet season kicks in. Rainy days jump noticeably and showers are frequent. Labour Day on May 1 is a public holiday, and Buddha's Birthday, on the eighth day of the fourth lunar month, often lands in May too. An umbrella and quick-drying shoes will help.

It was a hot month: 29°C by day and 24°C after dark. There were 12 rain days on average, roughly one day in three. A visitor in 2018 met 4 rain days; one in 2015 met 19. The average of 12 hid that gap.

About 9 days a month still climbed past 30°C, the ones where you looked for shade. May 2021 averaged 31.1°C by day, 2.1°C above the 20-year mean. Wet days did not mess around: about 23 mm each, the kind of rain that drives you into a doorway.
