Krabi weather,
live right now

November to April, the dry Andaman season. Calm sea, sunny days, all boat trips running, 28 to 32°C. December-January is peak with highest prices and crowds. May to October is the Southwest monsoon season, the sea gets rough, some islands are inaccessible, and heavy rain is frequent. Many beach resorts and some islands close entirely in September-October.

Technically yes (it is only reachable by boat, there are no roads), but reliably only in dry season (November to April). In monsoon season the longtail boats from Ao Nang stop running when the sea is too rough, which can leave you stranded or unable to reach it. Hotels on Railay operate year-round but most visitors in rainy season find themselves rerouting.

Krabi is quieter, less developed, more nature-focused. Phuket has bigger beaches with more infrastructure (clubs, shopping malls), Krabi has the dramatic limestone karst scenery (cliffs rising out of the sea). Krabi is better for climbing, kayaking, island-hopping day trips. Phuket is better for nightlife and large resort infrastructure. Weather patterns are near-identical, both are Andaman Sea coast.

Possible but not recommended. May to October brings reduced visibility (sometimes under 5 metres), strong currents, and many dive operators either close or run a reduced schedule. Peak diving is December to April when visibility can exceed 20 metres at sites like Koh Haa, Koh Bida and Hin Daeng.
