Best Time to Visit Port Blair, Andaman

Port Blair, the gateway to the Andaman Islands, enjoys a warm tropical climate year-round. The most pleasant months are November to April, when skies are clearer, seas are calmer, and most water-based activities operate at full swing. If you’re seeking value over perfect weather, the May shoulder and the June–September monsoon off-season can also be rewarding with fewer crowds and lower prices.

Quick Answer

• Overall best: Late November to April
• Peak season: December–January (highest demand and prices)
• Best for diving/snorkeling: December–April (often top underwater visibility); February–April is especially consistent
• Budget-friendly: June–September (monsoon; lush, quiet, but seas can be rough)

Season-by-Season Guide

November to April: Clear Skies, Calm Seas, Classic Season

Why go: This is the sweet spot for most travelers. Expect warm days (24–30°C), lower humidity than peak summer, good sunlight, and the widest range of open tours and islands. Underwater visibility is generally the best of the year, making it ideal for snorkeling at North Bay/Jolly Buoy and diving trips with operators in and around Port Blair.

• Pros: Best sea conditions, reliable ferries, vibrant marine life, festivals and events, great sunsets at Chidiya Tapu.
• Cons: Crowded around Christmas–New Year and late January; higher flight and hotel rates.

May: Warm, Less Crowded Shoulder

Why go: A good compromise if you want calmer seas without peak-season crowds. Days are hot (26–33°C) and humid, but most water activities still run and underwater clarity often remains excellent.

• Pros: Fewer tourists, better deals than winter, long daylight.
• Cons: Sultry afternoons; pre-monsoon showers or haze possible.

June to September: Monsoon Lushness and Deep Discounts

Why go: The greenest landscapes, empty viewpoints, and significant savings on stays. Expect periodic heavy showers, choppy seas, and potential schedule changes for boats and water sports for safety.

• Pros: Lowest prices, photogenic rain-washed greens, quiet attractions.
• Cons: Some islands and marine parks may close, ferries can be delayed, snorkeling/diving options limited by conditions.

October: Post-Monsoon Transition

Why go: Skies start to clear, the sea gradually calms, and the islands look freshly washed. Occasional showers and wind can linger, and the Bay of Bengal can see storm systems in late October/November.

• Pros: Reawakening season, fewer crowds than winter, vibrant foliage.
• Cons: Some days of unsettled weather; check sea conditions if planning water activities.

Best Time by Interest

Beach Relaxation and Sightseeing

Best: November–April. Ideal for Ross Island (Netaji Subhash Chandra Bose Island), North Bay, Corbyn’s Cove, Cellular Jail, and day trips into Mahatma Gandhi Marine National Park.

Snorkeling and Scuba Diving

Best: December–April; especially February–April for reliable visibility and calmer sea states. Water temperature is warm year-round (~27–29°C). Always check daily conditions with certified operators.

Honeymoons and Special Occasions

Best: Late November, February, and March balance weather with a bit more privacy than the holiday rush. Sunsets at Chidiya Tapu and evening shows at Cellular Jail set a romantic tone.

Photography and Nature

Best: December–March for clear horizons and golden light; October–November for dramatic skies and lush greens. Birding around Chidiya Tapu is rewarding roughly October–February.

Budget Travel

Best: June–September for off-season rates (often substantial), or May and October for shoulder-season value with better odds of good weather.

Events and Seasonal Openings

• Island Tourism Festival (January): Cultural performances and local crafts often centered around Port Blair.
• Beach and Food Festivals: Occasional city and beachside events around late winter to early summer.
• Mahatma Gandhi Marine National Park (Wandoor): Access to Jolly Buoy or Red Skin Island is seasonal and regulated; typically open outside the monsoon with one island operating at a time for conservation. Check the current schedule locally.

Crowds, Prices, and Booking Tips

• Peak demand: Mid-December to late January. Book flights, hotels, and inter-island ferries weeks to months ahead.
• Shoulder wins: Late November, February, March, and April offer a strong weather-to-cost ratio.
• Off-season savings: June–September can bring notable discounts on stays and tours, but be flexible.
• Ferry planning: Government and private ferries can sell out in peak times; secure tickets early, especially if pairing Port Blair with Havelock (Swaraj Dweep) or Neil (Shaheed Dweep).
