Cheung Chau under a typhoon signal what each warning means for the ferry and your day trip

In short: A Hong Kong tropical cyclone warning signal tells you how strong the wind is expected to be. It does not by itself decide whether your Cheung Chau ferry sails. Whether the boats run is a judgement about sea conditions made by the operator, Sun Ferry, so the thing to do when a signal goes up is to check with the operator rather than assume the timetable stops at a fixed number. This page explains what each signal means, how to check whether the ferry is running, and what to do if a signal is hoisted while you are already on the island.

The five typhoon signals, in plain words

The Hong Kong Observatory (HKO) issues numbered tropical cyclone warning signals. The official names and what each one means are:

Two timings are worth planning around. HKO's guidance is that winds normally reach gale force generally in Hong Kong within 12 hours after Signal No. 8 replaces Signal No. 3, so the instruction is to complete all precautions before the gales begin. And when Signal No. 8 is expected within two hours, HKO makes a pre-No. 8 special announcement — the cue people in Hong Kong use to stop what they are doing and get moving.

Will my Cheung Chau ferry run?

This is the question a signal really raises for a Cheung Chau trip, and the answer is not a simple "no at Signal No. 8". Sun Ferry states that whether sailings are suspended or resumed is a decision its coxswains make from the sea conditions. They take the tropical cyclone warning signal into account, but also severe gale, freak waves and storm tides, the conditions along the route, and safe navigation in open water. In other words, suspension is a sea-condition judgement, not an automatic trigger at a particular number.

So treat the timetable as a guide and confirm with the operator. Where to check:

If a signal goes up while you are on Cheung Chau

The island is small and open to the sea, so a rise in the signal mid-trip is mainly about shelter and the shoreline rather than getting home at once. HKO warns that storm surge can inundate low-lying areas or push seawater back inland, and that overtopping waves may occur along the coast; its advice is to stay away from the shoreline and not to take part in water sports. On Cheung Chau that means keeping off the promenade edge, the piers and the rocks, and giving the water margin a wide berth until the signal is lowered.

Before you travel in the typhoon season, have a fallback in mind. Crossings can stop for a period and resume once conditions allow, so build in the possibility of an unplanned night on the island — the accommodation guide covers guesthouses and holiday flats near the pier. For the live picture, follow HKO's own channels: the Dial-a-Weather telephone service on 1878 200, the "MyObservatory" mobile app, and the HKO website.

Beaches and the coast

Cheung Chau's two gazetted beaches — Cheung Chau Tung Wan Beach (Cheung Chau Beach Road, the island's main beach) and Kwun Yam Beach (Hak Pai Road) — are managed by the Leisure and Cultural Services Department (LCSD). Shark prevention nets are installed at these beaches, and lifeguard services run during the swimming season. When the weather turns, the LCSD directs the public to its press releases for the latest beach information, such as the hoisting of red flags. Check before you swim, and never treat a marked zone as safe during a signal. For the beaches themselves, see the Cheung Chau beach guide and the Tung Wan Beach guide.

Frequently asked questions

Will the ferry be cancelled when Signal No. 8 is hoisted?

Not automatically. Sun Ferry decides whether to suspend or resume sailings from the sea conditions — the warning signal is one factor, alongside severe gale, freak waves and storm tides. Check the hotline 2131 8181, the Sun Ferry website or the app for the current arrangement rather than assuming a fixed rule.

How do I find out if the ferry is running?

Call the Sun Ferry customer service hotline on 2131 8181, or check the Sun Ferry website or mobile app and the TV, radio and online news. For the signal itself, use HKO's Dial-a-Weather on 1878 200, the MyObservatory app or the HKO website.

Is it safe to swim or walk the coast during a signal?

No. HKO advises staying away from the shoreline during a tropical cyclone because of storm surge and overtopping waves, and the LCSD can hoist red flags at the beaches. Stay clear of the water and the exposed rocks until the signal is lowered.

Can I get off the island if the ferry stops?

If sailings are suspended, crossings resume when conditions allow, so plan for the possibility of waiting — or an overnight stay — rather than a guaranteed departure. The Home Affairs Department Emergency Co-ordination Centre hotline, 2835 1473, is activated when Signal No. 8 or above is issued if you need help.

Which signal should I watch for before a day trip?

Any signal is worth checking, but the change that most affects a Cheung Chau trip is Signal No. 8 replacing Signal No. 3: HKO's guidance is that winds normally reach gale force generally in Hong Kong within 12 hours of that change, and it makes a pre-No. 8 special announcement when Signal No. 8 is expected within two hours.

Where this information comes from

The signal definitions and the timing and coastline guidance are the Hong Kong Observatory's, from its Considerations for Issuing Tropical Cyclone Warning Signals and its Tropical Cyclone Warning Signals leaflet. The ferry suspension wording, the hotlines and the notification channels are from Sun Ferry's typhoon arrangements notice. Beach information is from the Leisure and Cultural Services Department's beach pages and press releases. This page is a standing guide with no dates: for the situation today, always use the operator's and HKO's live channels above.
