Krabi · Month comparison
May vs March
March ranks #1 overall vs May at #12. Still-excellent conditions at better value — the dry season's best month for most visitors.
May
#12 of 12 months
Strong option
Monsoon arrives — boat routes to Railay disrupted and prices drop sharply.
- ↑Prices drop 40–50% from peak season: Ao Nang hotels and even some Railay properties at their most affordable
- ↑Ao Nang virtually empty: restaurants, cafés, and the beach strip quiet without the dry-season crowds
March
#1 of 12 months
Best match
Still-excellent conditions at better value — the dry season's best month for most visitors.
- ↑Conditions nearly identical to February at noticeably lower prices: the dry season's best value window on the Andaman coast
- ↑All island tours, Railay longtail transfers, and Four Islands trips operating at full capacity

May trade-offs
- ↓Longtail boats to Railay Beach increasingly unreliable: cancelled or very rough on storm days — you can be effectively stranded on Railay if the sea turns
- ↓Four Islands tour suspended: Ko Poda and Chicken Island routes closed for the season as swells make the crossing unsafe
- ↓Rock climbing on Railay East wall rained out: wet limestone becomes dangerously slippery and most operators close
March trade-offs
- ↓Temperatures rising toward 34°C with increasing humidity: midday on the beach or mid-route rock climb becomes genuinely hot
- ↓Some Ao Nang hotel rates remain elevated through Thai school holiday weeks in late March
- ↓Sea conditions beginning to shift toward month end — occasional swell precedes the approaching monsoon
