Best Time to Visit Avis Island, Mayabunder (Andaman Islands)

Avis Island is a tiny, coconut-fringed sandbar off Mayabunder in Middle Andaman, prized for its powdery beach, clear shallows, and tranquil picnic vibe. Because access depends on weather, boat availability, and local permissions, timing your visit is key. Here’s a practical, season-wise guide to help you pick the ideal window.

Quick Answer

November to March is the best time to visit Avis Island. Expect dry, mostly sunny days, calmer seas for boat transfers, and clearer water for swimming and light snorkeling. October and April are workable shoulder months with warmer days and the odd shower. May to September (monsoon) brings rougher seas, frequent rain, and possible suspension of boat trips—generally not recommended.
