Is Andaman Good in Summer? A Guide to Visiting From March to May

Thinking of visiting the Andaman Islands between March and May? Summer in the Andaman archipelago brings warm sunshine, lively marine life and quieter crowds compared with peak winter months. This guide breaks down the weather, activities, island-by-island advice, safety and packing tips so you can decide whether a summer trip suits your travel style and how to make the most of it.

Overview: What "summer" means in the Andamans

The Andaman Islands lie in the Bay of Bengal and experience a tropical climate. Summer here runs roughly from March to May and is the pre-monsoon season. Temperatures typically rise, humidity increases, and the sea remains mostly calm — especially in March and April. By May you may notice hotter days and heightened humidity as the islands move toward the southwest monsoon that usually begins in June.

Why many travellers still prefer March–April

• Clear seas and excellent underwater visibility for snorkelling and diving.
• Less rainfall than monsoon months — fewer wet days than June–September.
• Warmer water temperatures that are comfortable for swimming without thick wetsuits.
• Fewer crowds compared with the winter peak, making beaches and tours more relaxed.

Weather and sea conditions: month-by-month

Understanding the differences between March, April and May will help you choose the best month for your priorities.

March

• Transition month from pleasant winter to warmer summer.
• Daytime temperatures are warm but not extreme; evenings are comfortable.
• Sea conditions are typically calm with very good visibility — ideal for diving and snorkelling.

April

• Warmer and more humid than March, but still a very good month for water activities.
• Many tours and operators are fully open — services and facilities are available across major islands.
• Sun protection becomes more important as UV intensity rises.

May

• Hottest month of the trio, with high humidity and more sultry days.
• The sea is still generally usable, though occasional short squalls can occur.
• Travel flexibility is useful: ferry services may be adjusted if the weather changes.

Activities: what to expect and when

Summer months suit a wide range of activities, but timing matters for the best experience.

Snorkelling and scuba diving

March and April are excellent for underwater visibility and abundant marine life. Many dive operators run trips daily; beginners can try shallow reef dives and PADI courses are available for those wanting certification. In May, visibility may vary but diving is still possible — always check with local operators about current conditions.

Swimming and beach time

Warm water temperatures make swimming enjoyable without heavy wetsuits. Popular beaches such as Radhanagar on Havelock (Swaraj Dweep) and Bharatpur on Neil Island are pleasant in summer — arrive early or late afternoon to avoid peak heat.

Island hopping and boat rides

Calm seas in March–April mean smoother ferry crossings and day trips to nearby islets for glass-bottom boat rides, ray and turtle spotting. By late May, keep an eye on weather forecasts and ferry advisories.

Wildlife and nature walks

Summer is a good time for short jungle treks, birdwatching and exploring limestone caves on islands like Baratang and North Bay. Carry water and go early to avoid midday heat.

Which islands are best in summer?

Each island has its personality. Here’s how they fare in summer months.

Port Blair

The administrative hub and entry point. Port Blair is convenient for settling in, completing paperwork and arranging onward travel. Visit Cellular Jail and Marina Park in the cooler parts of the day.

Swaraj Dweep (Havelock)

Known for Radhanagar Beach and strong dive sites, Havelock is a top choice in March–April for its clear waters and well-developed tourist infrastructure. Beach days and boat trips are especially rewarding early in the season.

Neil Island (Shaheed)

Smaller and quieter, Neil suits travellers seeking relaxed beaches and easy snorkelling. Warm summer days make the shallow reefs accessible and pleasant.

North Bay, Ross Island and Jolly Buoy

Popular day-trip destinations from Port Blair. North Bay and Jolly Buoy (when open) are great for snorkelling and corals — March and April offer the best visibility.

Little Andaman and Baratang

These islands are more remote with unique attractions like limestone caves and long surf beaches. Summer requires more planning but can be rewarding — expect hotter days and less tourist infrastructure.

Practical travel tips

Planning well helps you enjoy a comfortable summer trip to the Andamans.

Getting there

• Flights land at Veer Savarkar Airport, Port Blair, connecting from major Indian cities. Book early for preferred timings.
• Inter-island travel is by government ferries and private high-speed boats. Check schedules in advance as frequency varies by season.

Permits and regulations

Indian nationals have straightforward entry procedures; foreign nationals may need Restricted Area Permits (RAP) issued on arrival or online. Always carry valid ID and check current requirements before travel.

Where to stay

All major islands offer accommodation from budget guesthouses to resort-style properties. In summer, many resorts run attractive packages but availability can still decrease during school holidays — book early if you have fixed dates.

Health and safety

• Stay hydrated and avoid long exposure during peak sun hours. Use high-SPF sunscreen, a hat and light cotton clothing.
• Carry basic medications and insect repellent — mosquitoes can be more active in humid weather.
• Follow local advice for sea safety: only swim at lifeguarded beaches where advised and heed warnings about currents.

Money and connectivity

ATMs exist in Port Blair and on some larger islands but are limited elsewhere — carry sufficient cash. Mobile networks and internet are available in most inhabited areas but expect slower or patchy connectivity on remote islands.

Packing checklist for Andaman summer

• Light, breathable clothing (cotton/linen), swimwear, sarong or cover-up
• Sun protection: broad-spectrum sunscreen, sunglasses, wide-brim hat
• Comfortable sandals and water shoes for rocky shores and coral
• Snorkelling mask if you prefer personal gear (many tours supply equipment)
• Reusable water bottle, basic first-aid kit, insect repellent
• Waterproof bag for gadgets and quick-dry towels

Things to be mindful of

• Respect local ecosystems: don’t touch corals, avoid single-use plastics and keep beaches clean.
• Wildlife encounters: observe marine and birdlife responsibly — use binoculars and keep distance.
• Plan flexible travel days: weather can influence ferry schedules and dive operations.

Tip: If you prefer clearer water and calmer seas, aim for March–mid-April. If you can tolerate more heat and humidity for quieter beaches, late April–May works well too.
