#At a Glance
May is the hinge of the Hong Kong year. It starts as a warm spring and ends as summer: highs of 29°C, humidity at 83%, and 291mm of rain, almost double April's. Thunderstorms arrive on about six days, and the warning signals start to matter. It also holds one of the strangest and best festivals in the city, the Cheung Chau Bun Festival, which reaches its climax on Buddha's Birthday, Thursday 13 May 2027. Come for the islands, swim for the first time in the year, and plan each day around the sky.
#Weather in Hong Kong in May
Hong Kong in May averages 25–29°C (77–84°F) with around 15 days of rain, and crowds are medium.
The Hong Kong Observatory's 1991–2020 normals give May a high of 29°C / 84°F and a low of 25°C / 77°F, with about 15 wet days and 291mm of rain.
What that actually means for your trip:
- The rain changes character. April's light showers give way to heavy bursts, and about four days reach 25mm or more.
- Fog has gone. The harbour is usually visible again, at least between storms.
- Beaches come back to life as the sea warms.
- Humidity peaks now, at 83%, and it does not ease at night.
#Reading the Warnings
May is when visitors first meet the Observatory's warning systems. Typhoons are still rare, with a signal up on about a quarter of a day in the month, but rainstorm warnings are common enough to learn.
- Amber warns that heavy rain may develop.
- Red warns of serious road flooding, so get under cover and leave the hills.
- Black means more than 70mm an hour: stay indoors or take shelter until it passes.
- Typhoon No. 3 means strong wind, and most of daily life continues.
- Typhoon No. 8 means gales: schools and most offices shut, ferries stop and the MTR keeps running. Over 1991–2020 it averaged about one May day in thirty years, so it is unlikely this early.
#The Bun Festival
Cheung Chau's festival is a Taoist rite that turned into a spectacle. Three tall bamboo towers of buns stand outside the Pak Tai Temple, and on the night of the festival the island's trained climbers race up a steel tower to grab the highest ones. The other half of the day is the Piu Sik, a parade in which children, in costume, seem to float above the crowd on hidden frames.
- The date: the parade and final fall on Buddha's Birthday, Thursday 13 May 2027.
- The final: held around midnight. At the last festival about 1,650 free passes were handed out on the island from 10pm, one each.
- The food: much of the island turns vegetarian for the festival.
- Getting there: ferries from Central Pier 5, packed in both directions. Go early, and expect a long queue back.
#Island Days Between Storms
May is the right month for the outlying islands, as long as you keep an eye on the sky.
Each island has its own character and its own pier in Central. From Pier 4 boats run to Lamma, where a paved path links two villages and the seafood restaurants of Sok Kwu Wan. From Pier 5 they go to Cheung Chau, with its fishing harbour, Pak Tai Temple and the rocky coastal walk called the Mini Great Wall. From Pier 6 they head to Mui Wo on Lantau, a quiet base for buses towards the south coast beaches, and to Peng Chau, the smallest and sleepiest of the group.
Weekends and holidays cost more, and the ordinary ferry is about half the price of the fast one. On Cheung Chau at the last festival, the holiday fares were about HK$25 and HK$48 each way. Octopus works on both.
Check the forecast the night before. Thunderstorms arrive on about six days this month and they build quickly, so an island is a poor place to be under a red rain signal, with only a covered pier for shelter. A morning crossing and an early lunch usually beat a late start. Storms in May rarely last all day, and the hours after one are often the freshest of the week.
Do the Bun Festival as its own trip. On that day the island is a different place, with long queues in both directions, so keep your quiet Cheung Chau walk for another date.
#What to Do in Hong Kong in May
Plan the morning outdoors and leave the afternoon open.
Solo Travellers
Take the ferry to Cheung Chau on a normal weekday, when you can walk the Mini Great Wall path and the rocky coast in peace, then come back for the festival if you can. Lamma makes an easier half day.
Couples
Go south to Shek O for a first swim and a long lunch, and stay for the evening at Stanley. Rain is often short, so an afternoon shower need not spoil a day.
Families
The theme parks are still bearable, and school is in, so May weekdays are good for Ocean Park and Hong Kong Disneyland. Swim at a beach with lifeguards on duty, of which there are many.
Groups
A junk boat day to the outer islands is at its best late in the month, if the forecast holds; read the cancellation terms. Otherwise, the Bun Festival is a very good day out with friends.
#Getting Around
- Octopus works on the ferries as well as the MTR.
- Airport Express: HK$120 to Hong Kong Station and HK$105 to Kowloon on Octopus.
- MTR: HK$10.60 from Central to Tsim Sha Tsui on Octopus.
- Star Ferry: HK$5 upstairs on weekdays, HK$6.50 at weekends and on public holidays.
- Trams: HK$3.30 flat.
#Budget & Costs
| Travel style | Per day | What it covers |
|---|---|---|
| Budget | HK$800–1,300 | A hostel or guesthouse, cha chaan teng meals, the MTR |
| Mid-range | HK$2,000–3,100 | A central hotel, restaurants, an island day |
| Luxury | HK$5,500+ | Harbour-view rooms, a private junk |
What things cost:
| What | Price |
|---|---|
| Airport Express to Hong Kong Station, Octopus | HK$120 |
| MTR, Central to Tsim Sha Tsui | HK$10.60 |
| Star Ferry, upper deck, weekday | HK$5 |
| Bun Festival | Free |
| Taxi flagfall, urban red taxi | HK$29 |
Where the money actually goes:
- The first days of the month, with the mainland's May holiday, are the dearest.
- Late May is good value as the rain sets in.
- Hotels add a 3% tax and usually a 10% service charge, so check a rate includes both.
#Food & Dining
As the heat comes on, the city turns to cold drinks and light lunches: iced lemon tea, a plate of roast meat over rice, and rice-noodle rolls. On Cheung Chau, the ping on bao is the souvenir, a sweet bun stamped in red. Lychees and mangoes start to appear in the markets late in the month, and mango pudding makes the obvious dessert.
#Nightlife
Outdoor drinking is still pleasant in early May, and Lan Kwai Fong and SoHo are busy into the night. Storms can empty a terrace, so choose somewhere with cover. Happy Valley's Wednesday races continue through the month.
#Shopping
The mainland holiday in the first days of May makes Tsim Sha Tsui's big malls very crowded. Sham Shui Po stays a local market street. There is no sales tax.
#Culture & Etiquette
On Buddha's Birthday, temples such as Po Lin on Lantau hold a ceremony in which worshippers pour water over a small statue of the Buddha. Visitors are welcome, but keep clear of the line. On the Bun Festival parade route, let the floats go past, and do not reach for the children.
#Essential Local Phrases
| Cantonese | Meaning | When to use |
|---|---|---|
| 平安包 (ping on bao) | Safety bun | On Cheung Chau |
| 搶包山 (cheung bao saan) | The bun-scrambling race | On festival night |
| 佛誕 (fat daan) | Buddha's Birthday | On 13 May |
| 黑雨 (hak yu) | Black rain | On the warning screens |
| 落雨 (lok yu) | It is raining | Most afternoons |
| 唔該 (m goi) | Please, or thanks for a service | All day |
#Packing List
- Light, quick-drying clothes
- A compact umbrella
- A rain jacket for island days
- Swimwear
- Sun cream and a hat
- Mosquito repellent
- A dry bag for your phone
- A layer for the air-conditioning
#Backup Plans
- A red or black rain signal: go under cover and wait; these downpours usually pass within hours.
- Rained off: M+ at HK$190 and the Hong Kong Palace Museum from HK$70.
- Ferry queues on festival night: stay on Cheung Chau, if you can find a room, and book well ahead.
#Safety & Health
Dial 999 in an emergency. Flash flooding and landslips are the May risks on hill paths, so leave country parks at the first red signal. Mosquitoes return, and dengue is present in the region. Carrying a vape in a public place is also an offence, with a HK$3,000 fixed penalty. National security laws here are strict and cover visitors too: see First Time in Hong Kong.

Frequently Asked Questions
Is May a good time to visit Hong Kong?
It is a mixed month. Early May is warm and fine for swimming and island days, but rain almost doubles on April to 291mm, with thunderstorms on about six days. The Bun Festival on 13 May 2027 is the reason to come.
What is the Cheung Chau Bun Festival?
A Taoist festival on Cheung Chau island, with a parade of children in costume who seem to float above the crowd, and a midnight race up a tower of buns. In 2027 it peaks on Buddha’s Birthday, Thursday 13 May. Ferries leave from Central Pier 5.
What does a black rainstorm warning mean in Hong Kong?
More than 70mm of rain an hour has fallen or is expected, and it is likely to continue. The Observatory’s advice is to stay indoors or take shelter in a safe place until the heavy rain has passed. Leave the hills as soon as a red signal is issued.
How much does a May trip to Hong Kong cost?
Allow about HK$800–1,300 a day on a budget and HK$2,000–3,100 mid-range. The first days of the month are the dearest, with the mainland’s holiday, and late May is good value. Hotels add a 3% tax and usually a 10% service charge.
