Havelock Island, officially renamed Swaraj Dweep in 2018, is the crown jewel of India's Andaman archipelago, a tropical island roughly 70 kilometers northeast of Port Blair in the Bay of Bengal. It's the kind of place where your biggest decision each day is choosing between snorkeling over coral reefs at Elephant Beach, watching the sunset melt into the Andaman Sea from Radhanagar Beach (regularly ranked among Asia's finest), or paddling a kayak through tangled mangrove channels. The island's community reflects a mix of Bengali, Tamil, and Karen cultures, and the food leans hard on fresh-off-the-boat seafood: grilled whole fish, prawn curries in coconut milk, and butter-garlic lobster at laid-back beachside shacks.
Your ideal window for Havelock Island runs from early January through early April, when skies are clear, seas are calm, and underwater visibility peaks for diving and snorkeling. February is the driest month, with rain on just 4% of days, and the island sees its lightest visitor numbers of the year, meaning uncrowded beaches and easier restaurant bookings. January through March also delivers the best scuba diving conditions, with visibility reaching 15 to 30 meters at sites like Nemo Reef and Barracuda City. If you want slightly warmer shoulder-season conditions and don't mind building humidity, late October through December is a solid secondary option as the monsoon retreats and dive operations resume at full capacity.
Spring in Havelock Island, India
March through May is when Havelock's beaches are at their emptiest and accommodation deals are easiest to find. The first two months of this window, March and April, fall squarely in the island's dry season, with rain appearing on roughly 9% of March days and 16% of April days. That translates to long, uninterrupted stretches of sunshine, perfect for full days at Radhanagar Beach or snorkeling at Elephant Beach's coral gardens, where clownfish, parrotfish, and angelfish dart through the shallows. Highs average 90.1°F (32.3°C), so mornings before 10 AM are your best bet for comfort during a trek through the island's interior trails or a sunrise kayak through the mangroves near Havelock Jetty.
By mid-April, the island hits its peak heat, with highs climbing to 91.9°F (33.3°C) and overnight lows only dropping to 77.6°F (25.3°C). Humidity creeps upward too, so lightweight, breathable clothing and reef-safe sunscreen are non-negotiable. Scuba diving conditions remain excellent through most of this stretch, with calm seas and strong visibility at sites like Nemo Reef. May marks the transition toward monsoon, with rain probability jumping to 51%, and seas grow choppier as the season turns. Pack a light rain jacket if you're visiting in late May, and book ferry tickets well in advance since schedules can shift.
Summer in Havelock Island, India
June through August is monsoon season on Havelock, and the island transforms into a dramatically different place. Heavy rains roll in frequently, with precipitation likely on 57% to 61% of days, and seas become rough enough that most water sports operators suspend activities. Winds pick up noticeably, peaking in June. Ferries between Port Blair and Havelock still operate through private catamaran services like Makruzz, but cancellations due to extreme weather are possible, so build buffer days into your itinerary. Highs average 85.9°F (29.9°C) with lows near 76.3°F (24.6°C), slightly cooler than the spring heat, though humidity around 86% makes the air feel thick and heavy.
Despite the challenges, monsoon Havelock has its own appeal. The island's forests explode with green, interior streams that run dry most of the year fill with clear water, and bird activity spikes. Trekking through the island's jungle trails is more comfortable without the intense pre-monsoon heat, and you'll have beaches like Kalapathar and Vijaynagar virtually to yourself. Some beach shacks reduce hours or close entirely, and the dining scene slows down, but the restaurants that stay open tend to put extra care into their cooking. This is also the island's busiest tourism window by volume index, driven partly by domestic holiday travel, so don't assume rock-bottom prices everywhere. Carry motion sickness medication if you're prone to it; the ferry crossing can get bumpy in choppy monsoon seas.
Fall in Havelock Island, India
September kicks off with the tail end of monsoon: it's the wettest month of the year, with rain on roughly 67% of days, and seas remain unsettled. Dive operations begin reopening as October arrives and conditions improve, though visibility isn't yet at its January-to-March peak. By November, showers become less frequent (about 34% of days), the sea flattens out, and the full range of water activities comes back online: snorkeling trips to Elephant Beach, introductory scuba dives at Nemo Reef, jet skiing, and sunset kayaking. Highs across the season average 86.8°F (30.4°C) with lows of 76°F (24.4°C), warm enough that you'll want quick-dry clothing and a good hat for midday beach time.
Crowds are still relatively thin through September and October, and accommodation rates tend to be lower than the December peak. This shoulder window suits travelers who want decent weather without fighting for ferry seats or restaurant tables. November evenings, with the post-rain clarity, produce some of the island's most vivid sunsets over Radhanagar Beach. The beachside shack scene around Govind Nagar and Vijaynagar (Beach No. 3 and No. 5 areas) reopens fully, and fresh seafood, from grilled tuna to coconut prawn curry, returns to every menu. Bring a light waterproof layer for early fall, and consider booking your ferry from Port Blair at least two weeks out as November demand starts climbing.
Winter in Havelock Island, India
December through February is Havelock's peak season, and for good reason. The monsoon has fully retreated, skies are reliably clear, and the Andaman Sea turns glassy calm, delivering the best underwater visibility of the year for scuba diving and snorkeling. Dive sites like Johnny's Gorge, Seduction Point, and the Wall become accessible in ideal conditions, with visibility commonly stretching to 20 to 30 meters. Highs average 87.2°F (30.7°C) and lows settle to their most comfortable point of the year at 74.5°F (23.6°C), while humidity drops to its lowest levels (around 70%). The air feels noticeably lighter than any other time of year. December is the island's busiest month, so book ferries and accommodation well ahead; February, by contrast, draws the fewest visitors of any month, making it a sweet spot for crowd-averse travelers.
Rain is minimal: just 16% of December days and 7% of January days see significant precipitation, with February dropping to a mere 4%. That means almost every day is a full beach day. Sunrise yoga sessions on the sand at Radhanagar, a short trek to Elephant Beach for morning snorkeling, afternoon kayaking through the mangroves, and a grilled-fish dinner at one of the beachside cafes near Beach No. 3: this is the rhythm of a winter visit. Island hopping to nearby Neil Island is also smooth and reliable during these months. Pack light cotton layers for the evenings, strong sunscreen, and a reusable water bottle, as staying hydrated in the tropical heat matters year-round.

Travel Tips & Safety for Havelock Island, India
Getting to Havelock requires a two-step journey: fly into Veer Savarkar International Airport in Port Blair (daily connections from Chennai, Kolkata, Bengaluru, Delhi, and Mumbai), then catch a ferry from the jetty. Private catamarans make the crossing in about 90 minutes, while government ferries are cheaper but slower. Book ferry tickets at least two to four weeks ahead during peak season (December through February), as seats sell out fast. On the island itself, renting a scooter or motorbike is the most practical way to get around; the island is only about 15 kilometers end to end, and auto-rickshaws and taxis are also available. Foreign nationals need a valid Indian visa plus a Restricted Area Permit, which is issued on arrival at Port Blair airport.
ATMs exist on Havelock but can run out of cash, especially during peak season, so carry enough rupees for a few days and have a UPI-enabled payment app as backup. Stick to bottled or filtered water, use reef-safe sunscreen to protect the coral ecosystems, and bring insect repellent for evenings. Watch for jellyfish during the monsoon shoulder months, and always swim within marked zones where lifeguards are posted at Radhanagar Beach. The island has only a primary health care unit, not a full hospital, so pack any prescription medications you might need.
