Complete month-by-month breakdown of Krabi weather, sea conditions, rock climbing season, and hotel rates. Find the perfect time for your Andaman Coast escape.
Krabi is one of Thailand's most dramatic destinations — towering limestone karsts, emerald-green waters, and access to some of the best islands in Southeast Asia including Koh Phi Phi, Koh Lanta, and the Railay Peninsula. Its weather follows the Andaman Sea pattern, opposite to Gulf of Thailand destinations like Koh Samui.
Krabi's Climate
Krabi sits on Thailand's Andaman Coast and is governed by the southwest monsoon. This means its dry season (November–April) is the opposite of Koh Samui and Koh Phangan. When the Gulf of Thailand is wet, Krabi is dry — making it a useful alternative.
Dry season (November–April): Clear skies, calm seas, ideal for island hopping and rock climbing.
Wet season (May–October): Southwest monsoon brings heavy rain and rough seas. Some boat services to outer islands are suspended.
