Respect the season. In May to October, expect more swell and last-minute changes. Do not pressure operators to run in unsafe conditions.
Currents can build quickly on pinnacles and points. Stay close to your guide, keep good buoyancy, and avoid separation.
Use an SMB on ascent. Boat traffic is common on popular routes.
Keep profiles conservative if you are doing repetitive days, especially when adding deeper wreck dives.

May to October can bring larger swell and rougher crossings. Expect cancellations and avoid overcommitting to offshore itineraries without buffer days.

Popular bays and island routes have heavy longtail and speedboat traffic. Use an SMB (divers) or a bright snorkel vest and stay inside swim zones when present.

Shark Point area and exposed points at Racha Noi can run as drifts. Stay close to the guide, keep good spacing, and be ready for negative entries if briefed.

Phuket is hot and humid year-round. Dehydration increases fatigue and can contribute to dive risk. Carry water, limit alcohol between dive days, and sleep enough.

Follow marine-park rules and respect seasonal closures, especially for offshore parks like Similan.
Do not touch or stand on coral, and keep fins and gauges secured.
Never feed fish or chase turtles or sharks for photos. Let wildlife set the distance.
Choose operators that use moorings rather than anchoring on reefs, brief responsible behavior, and manage group size.
Reduce waste: carry a reusable bottle and refuse single-use plastics where possible.
