At 6:30 on the morning of Sunday 22 November, the sea off Bang Sak Beach will be full of swim caps. For most of the year this stretch of Khao Lak coastline is one of the quietest in Phang Nga — casuarina trees, soft white sand, and hardly a footprint. For one weekend, it becomes a world start line, as OCEANMAN — the global open-water swimming series — returns for its 2026 Phang Nga edition on 21–22 November [ref:1].
A quiet beach with a world-sized weekend
Bang Sak sits about four kilometres north of Pakarang Cape at the top end of Khao Lak, loved precisely because it stays uncrowded: clear water, fine sand, and rows of casuarina pines throwing striped shade across the beach [ref:2]. It is the kind of shore where locals walk at sunrise and children hunt for shells at low tide. That calm is exactly what makes race weekend feel so special — the same gentle water that welcomes morning walkers will carry swimmers from across the world.
The Andaman Sea here averages around 28°C in late November, with daytime air near 34°C — so warm, in fact, that wetsuits are not allowed in any of the races. It is swimming in its purest, lightest form: cap, goggles, and one mandatory inflatable safety buoy tethered at the waist [ref:1].
Five races, one sea — from 500 metres to 10 kilometres
The weekend is built so that almost anyone can find a distance that fits:
- OCEANMAN — the full 10 km, starting 6:30 AM on Sunday 22 November
- Half OCEANMAN — 5 km, off at 7:00 AM the same morning
- Sprint — 2 km at 3:00 PM on Saturday 21 November
- OceanTeams — a 3 × 500 m relay at 4:00 PM, open to male, female, and mixed teams
- OceanKids — a joyful 500 m splash at 5:00 PM, just before the opening ceremony [ref:1]
The 10 km is a proper journey: swimmers have 4 hours 30 minutes to finish, with cut-off gates at 3 km (1h30) and 6 km (3h), and three floating feeding points along the course where paddlers on kayaks hand up drinks — the 5 km race has one. Every finisher, from the 10 km champions to the smallest OceanKids, receives a finisher medal, and trophies go to the top three overall and in each category [ref:1].
Saturday evening belongs to the community
Race weekends here are as much about the shore as the sea. On Saturday evening the beach hosts an opening ceremony at 5:30 PM, an award celebration at 6:00 PM, and — our favourite line on the official programme — a 7:00 PM "dinner feel Thai local food", when swimmers from dozens of countries sit down together over southern Thai cooking under the casuarinas [ref:1]. Local restaurants and stalls along Bang Sak get their busiest, warmest weekend of the season.
How to enjoy it, whether you swim or not
If you are in Phang Nga or Phuket in late November, this is one of the easiest world-class events to enjoy up close. Spectating is free and wonderfully close — the start and finish are both on Bang Sak Beach, so you can watch swimmers come home metres from your feet. Every swimmer receives accident insurance, a race bag with swim cap, shirt, and timing chip, and there is a merchandise shop and full medical support at the venue [ref:1].
And if the weekend sparks something, the series keeps flowing: OCEANMAN stages races from Malta and Ibiza to Dubai and Cyprus this season, with a Krabi edition set for March 2027 — meaning the Andaman coast will host the open-water world twice within a few months [ref:1].
One quiet beach, five races, and a sea at bath temperature. Somewhere between the 6:30 AM start gun and a child's 500-metre splash on Saturday afternoon, Bang Sak will spend a weekend being exactly what it always is — warm, welcoming, and open to everyone.
