Field notes

Thailand's #2 island after Phuket — Gulf-of-Thailand-side, in the Surat Thani archipelago. Bophut and Mae Nam (the calmer northern-coast beaches) are the typical long-stay nomad zones; Chaweng is the touristy main strip. Same Thai DTV. The structural draws are an established expat-and-coworking scene (Samui has been a long-stay base since the 1990s), direct flights from Bangkok and most regional capitals (the Bangkok Airways monopoly keeps prices high but service consistent), and proximity to Ko Phangan and Ko Tao for diving weekends. Wet season (October–November) brings real rain.

Tropical maritime (Gulf of Thailand) — wet season is offset from the rest of Thailand because of the Gulf-of-Thailand monsoon pattern. Dry first-half of the year (December–April) is bright sunny and the postcard window. Late-year wet season (October–November) brings the heaviest rainfall and rough seas. Sea-water temperatures stay swimmable year-round.
