Frequently Asked Questions About Andaman Weather
Q: What is the absolute best time to visit Andaman Islands?
The absolute best time is from December to February. You'll enjoy perfect weather with temperatures between 23-29°C, calm seas ideal for all water activities, minimal rainfall, and excellent underwater visibility for diving. However, this is also peak tourist season with higher prices and crowds.
Q: Can I visit Andaman during monsoon season?
Yes, you can visit during monsoons (May-September), but with limitations. You'll get 50-70% discounts on hotels and flights, experience lush green landscapes, and enjoy peaceful surroundings. However, expect rough seas, cancelled ferries, no water sports, and heavy rainfall. It's ideal for budget travelers who don't mind indoor activities.
Q: How hot does it get in Andaman?
Andaman has a tropical climate with temperatures rarely exceeding 35°C even in peak summer. The hottest months are April-May with temperatures reaching 33-35°C. However, the sea breeze keeps it bearable. The coolest months are December-January with pleasant nights around 22-23°C. Always use sunscreen as the tropical sun is strong year-round.
Q: Which months should I avoid for water sports?
Avoid May to September for water sports. During these monsoon months, the sea is rough with dangerous currents, most operators suspend activities, and beaches often have red flag warnings. October is transitional with some activities resuming. November onwards, all water sports operate normally with calm sea conditions.
Q: Is there a cyclone season in Andaman?
Andaman has a low cyclone risk compared to India's east coast. The slight risk period is October-December during the northeast monsoon. However, direct hits are rare due to the islands' location. The government has excellent early warning systems, and tourist activities are suspended well in advance if there's any threat.
Q: What's the weather difference between islands?
Weather is fairly uniform across all tourist islands (Port Blair, Havelock, Neil). However, the northernmost islands like Diglipur may receive slightly more rainfall. Havelock and Neil might be 1-2°C cooler than Port Blair due to stronger sea breezes. Overall differences are minimal and shouldn't affect your travel plans.
