Phuket and Andaman Sea Forecast: 2–7 July 2025
The latest Phuket and Andaman Sea forecast covers 2 July to 7 July 2025, and it points to a week that starts unsettled and steadily improves. This is the Weather Forecast for the Andaman Sea Region, Thailand, and it matters most if you are travelling by boat between Phuket, Krabi, Phi Phi, Koh Lanta or the surrounding islands during that window.

What changed across the week
The main shift comes mid-week. Wednesday brings the roughest water of the period, with waves of 1.5–2m and thunderstorms likely. From Friday the seas turn slightly calmer, and by Saturday and Sunday wave heights drop under 1m with calm, boating-friendly conditions.
Temperatures stay steady throughout, in a narrow 27–31°C band, so the deciding factor for your trip is sea state rather than heat.
Who this affects
Choppy seas mainly affect passengers on open-water crossings and smaller speedboats, which feel swell more than larger ferries. Travellers prone to seasickness, families with young children and anyone carrying dive or photography gear should favour the calmer days later in the week.
Land services are less exposed to sea conditions, though heavy rain can slow road journeys.
Practical tips for travellers
- Plan island-hopping and open-water days around Saturday 5 and Sunday 6 July, when conditions are best.
- Leave buffer time if you have onward flights or connections on Wednesday 2 July.
- Check tide times before booking early-morning or late-afternoon departures, as some piers are tide-dependent.
- Confirm your operator's policy on weather-related cancellations and changes at the time of booking.
