Peak Season (Jan, Feb, Mar, Apr, Nov, Dec)
These months bring Koh Samet's most reliable weather — low rainfall, comfortable temperatures, and ideal conditions for all activities. Crowd levels are at their highest and accommodation prices peak; book well in advance for popular properties. The tradeoff in cost and crowds is worthwhile for first-time visitors who want the full experience.
Shoulder Season
The weeks immediately before and after peak season offer a compelling balance: mostly good weather, significantly lower prices, and fewer crowds. Some activities may have reduced availability, but the overall experience is often better value than peak. Experienced travellers frequently prefer this window.
Low Season / Wet Season (Jun, Jul, Aug, Sep, Oct)
Koh Samet's low season brings Wet season; choppy sea. Many visitors avoid these months, which has the paradoxical effect of creating good deals — prices drop 30–50%, guesthouses are quiet, and the atmosphere is more local. If your activities don't depend on weather, the low season can be excellent value.
