Solo nomad baseline assumes one person, central 1-bedroom, modest groceries, 20 GB mobile, 4 paid coworking days/month. Where the rent basis above notes a private-market premium, expat condo budgets run higher than this baseline.

Koh Samui is Thailand's third-largest island in the Gulf, international airport directly on the island, an established expat retiree community, and a structurally different climate pattern from western Thai coasts.
editorial
The case & the friction.
The case is the package: a working tropical island of about 70k residents + significant tourism inflow, the Big Buddha Wat Phra Yai, Lamai and Chaweng beaches, and the surrounding Ang Thong Marine National Park. The Samui International Airport handles direct flights from Bangkok, Singapore, Kuala Lumpur, Hong Kong. A 1-bed in Chaweng, Lamai, or Bophut runs ฿20,000-40,000/month ($560-1,120) furnished.
Same Thailand visa picture as elsewhere, DTV Destination Thailand Visa (2024), Elite Visa, Long-Term Resident Visa, 60-day visa exemption. Thai essential past expat contexts; English widely usable in tourist districts.
The friction is the Gulf-of-Thailand reversed monsoon, the western Thai coast's dry season is Samui's wet season (October-December brings the heaviest rain), and the western coast's wet season is Samui's dry. The island gets less rain overall than Phuket. Tourism load varies sharply by season; rents 30-50% higher during high season Dec-Feb. Air clean. No quake exposure; mild tropical storm exposure (the 2017 Tropical Storm Pabuk hit Samui directly, but storms are rare).

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.
