Koh Tao is a 21-square-kilometer dive school with a small nomad bolt-on, fine for two months between certifications, structurally wrong as a base.
editorial
The case & the friction.
ExpatWhy editorial
2,000 official residents (closer to 4,000-5,000 with seasonal divers) on the smallest of the three Gulf islands. Sairee Beach on the west holds 80% of the dive shops, expat bars, and the few coworking-adjacent cafes; Koh Nang Yuan, the three-islet sand-spit cluster, sits a 10-minute longtail north and is the postcard. The PADI Open Water here is genuinely the cheapest globally, THB 9,500-11,000 ($265-310) including 4 dives.
A basic Sairee bungalow runs THB 7,000-12,000/month ($195-335) in low season, doubling Dec-Feb; a real AC studio with usable wifi sits THB 14,000-22,000 ($390-615). Accommodation supply is tight, most contracts are weekly, not monthly. Rainy season is Oct-Dec with the worst window late Oct to mid-Nov; this is also when ferry cancellations spike and the island periodically goes 36-48 hours without easy mainland connection.
DTV applies (5-year, 180-day stays, THB 500K savings). Internet is the worst of the three Gulf islands, 4G on AIS is the only honest answer; bungalow fiber rarely sustains 25 Mbps and drops with rain. No hospital and no pharmacy beyond basics, anything serious means a 90-minute ferry plus ambulance to Koh Samui's Bangkok Hospital. English is functional in dive shops, weaker elsewhere.
verdict
For divers willing to live around tank fills for 6-10 weeks, wrong island for anyone with chronic medical needs, dependents, or a job that punishes missed standups.

National-average international-school primary tuition, aggregated from published 2025/26 fee schedules across the country's international schools. Country baseline, not anchored to schools in this specific city; the real figure for a given school varies with tier, location and grade. Preschool = full-day international preschool, annual. Secondary is an estimate, modelled as a published uplift over primary (low +20%, typical +30%, high +40%), since secondary tuition rises with grade; it is not a separately sourced figure.
Tuition only. Excludes one-off enrolment/capital levies, school bus, lunch, uniforms and exam fees, which add materially at most schools.
