Macau casinos can’t seem to buy a break, as Typhoon Mujigae dampens visitation during the Golden Week holiday.

Macau casinos have traditionally enjoyed a healthy revenue bump in October as Chinese tourists flock to the island during the weeklong national holiday, which kicked off last Thursday. The bump would be especially welcome this year, as Macau reported its 16th straight month of revenue decline in September.

The early numbers were favorable, with total visitor arrivals up 7.6% on Oct. 1, while mainland Chinese visitation rose 18.3%. Over the first three days, the total number of mainland tourists was up 16.4% year-on-year.

But then Mujigae, which had been brewing offshore for a number of days, hit Macau with torrential rain and strong winds. The effect was much stronger on the mainland, particularly in Guangdong province, from which Macau draws most of its visitors. Nearly 200k residents were ordered to evacuate as China issued a red alert – its highest weather-related warning.
