Beach Safety at Da Nang and Hoi An: Rip Currents and Flag Guide
💡 Da Nang's My Khe Beach has trained lifeguards in flagged zones during peak season (approximately 4:30 AM to 7 PM daily), and the city's beaches use a green, yellow, and red flag system. The UK Government explicitly warns of "dangerously strong currents" around Hoi An. If caught in a rip current, do not fight it: swim parallel to shore and signal for help.
Key takeaways
- Da Nang's main beaches (My Khe, Non Nuoc, My An) use green (safe), yellow (caution), and red (no swimming) flags. Only enter the water in a green-flagged zone with a lifeguard visible.
- The UK Foreign Office travel advisory explicitly warns of dangerously strong currents around Hoi An beaches. October and November are the most dangerous months, driven by typhoon swells and intensified rip currents.
- Lifeguards at My Khe Beach operate approximately 4:30 AM to 7 PM during peak summer season, with rescue posts roughly every 200 metres along the beach. Confirm hours on arrival.
- If caught in a rip current: stay calm, float, and swim sideways (parallel to shore) until you exit the current, then angle back toward the beach. Signal loudly to the lifeguard rather than exhausting yourself swimming against the pull.
- For a beach emergency, call 115 (ambulance) or the Da Nang Tourist Support Center at (0236) 3 550 111. Save the Family Medical Practice 24/7 line (+84 913 917 303) as a backup.
What do the beach flag colors mean at Da Nang and Hoi An beaches?
Vietnamese beaches in Da Nang use the international beach flag color system. A green flag means conditions are safe and swimming is permitted in the marked zone. A yellow flag means caution: moderate currents or hazards are present and you should stay close to shore. A red flag means the water is dangerous and swimming is prohibited.
Flags are displayed on poles along the beach and changed throughout the day as conditions shift. Always check the flag nearest to your entry point. At Hoi An's Cua Dai and An Bang beaches, flags are also used, but lifeguard coverage is more limited than at Da Nang's main beaches.
My Khe Beach, Da Nang: lifeguards, zones, and when it is safe to swim
My Khe Beach is Da Nang's primary swimming beach, stretching several kilometres along the coast east of the city centre. Da Nang city deploys trained beach rescue teams during the peak summer season (roughly March to September). According to city safety guidance, lifeguards are stationed approximately every 200 metres, with eight first-aid posts along the beach.
Lifeguard hours are approximately 4:30 AM to 7 PM during peak season, based on Da Nang city guidance reported by Vietnamese state media. After 7 PM there is no on-duty coverage: avoid swimming at night. These hours are approximate and can change seasonally. Confirm at the beach on the day. Swim only within the floating buoy zones, which mark the areas monitored by rescue teams.
Are Hoi An's Cua Dai and An Bang beaches safe to swim?
Hoi An's beaches are popular, but the UK Government's official travel advice is explicit: there can be "dangerously strong currents" around Hoi An. October and November bring typhoon swells from the South China Sea, making Cua Dai and An Bang beaches genuinely hazardous. The safest swimming period is February to August, when conditions are generally calmer.
Even in the safe season, currents can strengthen without warning. Cua Dai Beach has experienced significant coastal erosion over the past decade, which alters the underwater terrain and can create unexpected drop-offs close to shore. Lifeguard coverage at Hoi An is more limited than at Da Nang: resort-fronted stretches have better supervision, while open stretches have little or none. If you are unsure, watch whether locals are swimming before entering.
What to do if you are caught in a rip current?
Rip currents are the leading cause of beach drownings worldwide, and they form on any open beach, including My Khe and Cua Dai. A rip pulls swimmers away from shore but not underwater: the danger is exhaustion from fighting it.
Recognize a rip by looking for: a channel of darker or choppier water running straight out from shore; foam, seaweed, or debris moving steadily offshore; a gap in the wave line where the surf looks flat. If you are caught:
- Stay calm. Do not swim directly back to shore against the current.
- Float and conserve energy. Signal to a lifeguard by waving both arms.
- Swim sideways, parallel to the beach, until you are out of the current's pull.
- Once free, angle back to the beach diagonally, not straight in.
Da Nang's official beach safety guidance and Australia's Smartraveller both confirm this technique. The most dangerous mistake is to panic and swim directly against the current until exhausted.

FAQ
What does a red flag mean at Da Nang beaches?
A red flag means the water is dangerous and swimming is prohibited - due to strong currents, rough seas, or storm conditions. Beach staff enforce this. Do not enter the water when a red flag is flying, even if the sea looks calm near the shore. Surface appearance does not reveal what is happening below or offshore.
Are there lifeguards at Hoi An beaches?
Coverage is limited compared to Da Nang. Some resort-fronted stretches of Cua Dai and An Bang beaches have lifeguards during peak season. At An Bang Beach, rescue staff are reportedly active from around 6 AM to 6 PM in the main season. Do not assume lifeguard presence at any open or unmarked stretch of Hoi An beach.
Is it safe to swim at My Khe Beach after dark?
No. Lifeguard duty at My Khe Beach ends around 7 PM in peak season. After that, there is no on-duty rescue coverage. Rip currents are the same at night, but visibility is zero and nobody is watching. Night swimming on any Vietnamese beach carries a high and avoidable risk.
What should I do if I see someone in trouble in the water?
Shout to the nearest lifeguard immediately and point to the person. Call 115 (ambulance). Do not enter the water yourself unless you are a trained ocean rescuer: a panicking person in the water can pull you under. Throw a life ring, a rope, or any buoyant object within reach and keep the person in sight while help arrives.
How far is it from Hoi An beaches to Da Nang's hospitals?
Cua Dai and An Bang beaches are roughly 30 km from central Da Nang. A Grab ride to Da Nang Hospital (124 Hai Phong, 24/7 emergency) takes approximately 40 to 50 minutes depending on traffic. For a serious emergency, call 115 for an ambulance and simultaneously arrange the fastest transport available.
