May is the beginning of Hong Kong's wet season, and it's worth knowing what that means before you book. The city is fully operational and compelling year-round, but May brings heat, humidity, and the first significant rains of the year. Go in prepared and you'll have a great trip. Go in expecting pleasant spring weather and you'll be caught off guard.

Weather

Temperatures in May range from 23°C to 30°C with high humidity, often above 80%. Rain increases through the month, and heavy downpours can arrive quickly and last for hours. Pack light, breathable clothing, an umbrella or compact rain jacket, and accept that you will get wet at some point. The heat and humidity together can make extended outdoor walking genuinely tiring.

Crowds and Prices

May is not peak tourist season for Hong Kong, which means lower hotel prices and shorter queues at popular spots compared to winter and Chinese New Year. The city's major attractions, the Peak, Victoria Harbour, temple districts, are still very busy, but manageable. Budget for a city that is expensive on food and accommodation at any time of year.

What's On

1 May is a public holiday in Hong Kong (Labour Day). Some businesses close but the city's major attractions and restaurants stay open. It's a popular day for local outings so expect parks and waterfront areas to be particularly lively.

Buddha's Birthday, a public holiday in Hong Kong, falls in May depending on the lunar calendar. Monasteries such as Po Lin on Lantau Island host special ceremonies and attract large numbers of visitors. It's worth visiting for the atmosphere even if you're not there specifically for the holiday.

Dragon Boat Festival preparations begin in late spring, and smaller practice sessions start appearing on the water.

One Thing to Watch

Typhoon season officially begins in May, though serious storms are more common from July onwards. The city has a well-established warning system with numbered signals, and life shuts down during high-signal events. Check the Hong Kong Observatory app and understand what the different signal levels mean before you arrive. A signal 8 or above means everything closes. It's rare in May but not impossible.

Hong Kong rewards the prepared visitor. Know the city, know the weather, know the transport.
