Yes – you can visit Andaman in July, and the rains buy you the islands at their greenest, emptiest and cheapest. July is the peak of the south-west monsoon, with daytime highs around 29–30°C, roughly 300-400 mm of rain across about 17 wet days, and seas rough enough to suspend most open-water activities. Go in July for heritage Port Blair, lush island scenery and the year’s lowest package prices; skip it if your trip depends on calm-water snorkelling or guaranteed inter-island ferries. This guide covers July’s weather, what is open versus closed, and the 10 best places to visit in Andaman & Nicobar in the monsoon – each with an honest note on how it holds up in the rain.

Is Andaman Worth Visiting in July?
July is peak monsoon in Andaman. Expect around 30°C, heavy rain (~300–400 mm over ~17 days) and rough seas, with the national-park snorkel boats closed and most water sports suspended or weather-dependent. It’s worth it if you want lush-green islands, near-empty heritage sites and the lowest prices of the year. It’s the wrong month if your trip hinges on calm-water snorkelling, scuba on demand or guaranteed inter-island ferries.
Our travel writers find July works best as a Port Blair-and-near-islands trip rather than an ambitious island-hopping one. The heritage sites, museums and short Ross Island hop stay reliable through the rain, the islands look their most green, and resorts and packages run at off-season rates. The trade-off is firm: build in buffer days, keep the itinerary flexible, and treat ferries and water sports as bonuses rather than guarantees.
Andaman Weather in July 2026 - Temperature, Rainfall & Sea
July sits squarely in the south-west monsoon (June–September). Days are warm and humid rather than hot, broken by frequent heavy showers and thunderstorms, and the Andaman Sea runs rough. Here is what to plan around.
| July weather metric | Typical value |
|---|---|
| Average high | ~29-30°C |
| Average low | ~24–27°C |
| Sea temperature | ~28–29°C (warm) |
| Rainfall | ~300–400 mm (peak SW monsoon) |
| Rainy days | ~17 days |
| Humidity | ~81–84% |
| Sea & swell | Rough – peak south-west monsoon |
| Water sports & ferries | Most water sports suspended / weather-dependent; ferries run reduced, weather-permitting |
Figures are typical July averages for Port Blair (sourced from climate aggregators weather-and-climate.com and Weather Spark); actual conditions swing day to day in the monsoon, so check a 3–5 day forecast before you book ferries or activities.
What's Open and What's Closed in Andaman in July
This is the single most useful thing to know before you go – and the question most monsoon guides skip. July does not close Andaman down, but it changes what you can realistically do. Port Blair’s heritage and indoor sights run normally; the water-based and far-island experiences are the ones that get curtailed.
| Experience | Status in July (monsoon) |
|---|---|
| Cellular Jail, museums, temples (Port Blair heritage) | Open as normal, year-round |
| Cellular Jail light-and-sound show | Runs on dry evenings; can be paused in heavy rain |
| Ross Island (NSCB Dweep) day trip | Short ferry – runs weather-permitting |
| Inter-island ferries (Port Blair–Havelock–Neil) | Reduced & weather-dependent (e.g. Havelock-Neil ~1 vs 3 daily sailings) |
| Scuba diving (Havelock / Swaraj Dweep) | Calm early mornings only; reduced, not guaranteed |
| Jolly Buoy / Red Skin national-park snorkel boats | Closed June-October (reopen November) |
| Glass-bottom boats & Elephant Beach water sports | Suspended on rough-sea days |
| Baratang limestone caves / mud-volcano convoy | Weather-dependent; stops on cyclone alerts or heavy rain |
| Open-water swimming | Unsafe – rough seas; follow red-flag advisories |
The pattern is consistent. Heritage and indoor Port Blair is dependable; the islands and the open water are conditional. Scuba is the one exception worth flagging – it isn’t banned in July, but at Havelock it runs only on calm early mornings, so it’s a maybe, not a plan.

Cellular Jail - the all-weather highlight of any July trip
The Cellular Jail in Port Blair is the one sight that’s genuinely better in the monsoon – largely covered, rarely crowded off-season, and on dry evenings the light-and-sound show on the role of this colonial-era prison in India’s freedom struggle still runs. Entry is a nominal INR 30, about 15 km of easy road from the airport. Start your July trip here; it’s the most reliable stop on the list.

Anthropological Museum - indoor, and open whatever the weather
Founded in 1975, this Port Blair museum documents the islands’ indigenous communities – the Onge, Sentinelese, Jarawa, Great Andamanese, Shompen and Nicobarese – through tools, photographs, handicrafts and weapons. It’s fully indoors, which makes it an obvious rain-day plan. Pair it with the Cellular Jail for an all-weather half-day in town.

Vetrimalai Murugan Temple - a covered, all-weather stop
This Hindu temple in Port Blair, dedicated to Lord Murugan, was first established in 1932 and rebuilt after Independence in Dravidian style. It’s a quick, covered visit that holds up in any weather, and it’s easy to reach – a good cultural stop to fold into a Port Blair day, rain or not.

Ross Island (Netaji Subhash Chandra Bose Dweep) - a short, weather-permitting hop
Just 3 km east of Port Blair, the former British administrative headquarters now sits half-reclaimed by jungle, with colonial ruins, a small museum, a cemetery and a 10-metre lighthouse over the Bay of Bengal. The boat ride is short, so it often runs even in the monsoon, but only on calm, dry mornings. Go on a clear morning, and check the day’s ferry status before you set out.
Radhanagar Beach, Havelock (Swaraj Dweep) - for the scenery, not the swim
Radhanagar – long rated among Asia’s finest beaches – is at its most green and dramatic in the monsoon, with moody skies and an empty shoreline. But the sea is rough, and the coast guard is posted there for a reason. In July this is a walking-and-photography visit, not a swimming one. Come for the views, and stay out of the wate
Wandoor Beach - green and quiet, but the marine-park boats are off
About 25 km from Port Blair, Wandoor is the gateway to Mahatma Gandhi Marine National Park. In peak season it’s a snorkelling launch point. In July the national-park day boats to the coral islands are closed and swimming is unsafe, so it becomes a scenic, low-key beach stop. Visit for the setting; the snorkelling stays off until November.
Bharatpur Beach, Neil Island (Shaheed Dweep) - white sand and easy walks
Bharatpur is a shallow, white-sand beach on Neil Island with Bay of Bengal views and, in season, glass-bottom boats. In July those water sports run only on calm days, but the beach itself is an easy, family-friendly stroll between showers – as long as the Port Blair–Neil ferry is running that day. It’s pleasant for the scenery; just treat the water sports as a maybe.
Red Skin Island - coral island scenery, snorkelling closed
Around 30 km south-west of Port Blair inside Mahatma Gandhi Marine National Park, Red Skin is a coral-rich island usually visited for shallow-water snorkelling. The national-park snorkel boats are closed June-October, so in July it’s a conditional, scenery-only pick, and often not reachable at all. Check before you plan a day around it – you’re likely better off saving it for November onward.
Baratang Island - a weather-dependent adventure
About 100 km from Port Blair, Baratang is reached by a road convoy through the Jarawa reserve plus a boat ride, out to mangrove creeks and limestone caves. The convoy and boat run on days without cyclone alerts or heavy forest-area rain, so it’s genuinely possible in July, just never guaranteed. Go on a clear day with an early start, and keep a backup plan in your pocket.
Mud Volcanoes - only if the weather cooperates
Andaman has more than 25 small mud volcanoes, mostly around Baratang and Diglipur, formed by escaping hydrocarbon and methane gases. They sit on the same weather-dependent Baratang route, and the trails close in heavy rain. Treat them as a conditional add-on to a Baratang day, not a trip you build around.
If your dates are flexible, it is worth comparing the shoulder months either side – see our guides to Andaman in June and Andaman in August, the two monsoon months that bracket July, or the year-round places to visit in Andaman if you are still choosing when to travel.
July Travel Tips & the Year's Lowest-Price Booking Window
July’s biggest draw is value. Because it is firmly off-season, hotels, resorts and tour packages run at the lowest rates of the year — often well below peak-winter prices — and the islands are close to empty. The trade-off is weather risk, which a few simple habits manage:
- Build in buffer days. Keep at least one buffer day in Port Blair before your flight home, in case a ferry is cancelled on rough seas.
- Plan ferries loosely. Book inter-island ferries early and check the day’s sailing status – off-season schedules are thinner and weather-dependent.
- Pack for rain and swell. Pack a quick-dry rain jacket, waterproof bag for electronics, sandals with grip, and motion-sickness tablets for choppy ferry crossings.
- Front-load the reliable. Lead your itinerary with all-weather Port Blair sights, and treat beaches, scuba and far islands as fair-weather bonuses.
- Cover the downside. Travel insurance that covers weather cancellations is worth it in the monsoon.
On price, July genuinely is the cheapest window to plan an Andaman trip — the catch is the weather, not the cost.
How to Plan an Andaman Trip in July (Step by Step)
Step 1: Fly into Port Blair. Veer Savarkar International Airport is the single gateway. Monsoon flights can be delayed, so avoid tight same-day onward connections.
Step 2: Spend the first days on all-weather Port Blair. Cellular Jail, the Anthropological Museum, Murugan Temple and the Ross Island hop are the dependable core of a July trip — schedule them first.
Step 3: Add islands as fair-weather bonuses. Book Havelock (Swaraj Dweep) or Neil (Shaheed Dweep) only with flexible dates, and check ferry status each morning before committing.
Step 4: Treat water sports as a maybe. Scuba runs on calm Havelock mornings only and the national-park snorkel boats are closed until November – plan the trip so nothing depends on them.
Step 5: Keep a buffer day before your flight. Hold your last night in Port Blair so a cancelled ferry can’t make you miss your departure.
Step 6: Book early for the off-season rate. July carries the year’s lowest package prices, but ferries and the best-value rooms still sell out – lock them in ahead.
Frequently Asked Questions About Andaman in July
Yes, if you go for the right reasons. July is peak monsoon, so it suits travellers who want lush-green islands, near-empty heritage sites, fewer crowds and the year's lowest prices. It is not the month for guaranteed snorkelling, calm-sea swimming or reliable island-hopping - for those, November to April is far better. Plan a Port Blair-and-near-islands trip with buffer days and July rewards you.
Andaman in July is warm and humid rather than hot. Daytime highs sit around 29–30°C and nights around 24–27°C, with the sea a warm 28–29°C and humidity in the low 80s. The heat is moderate; it is the heavy monsoon rain (~300–400 mm over about 17 days) and the rough seas, not the temperature, that shape a July trip.
Port Blair's heritage and indoor sights run as normal - the Cellular Jail and its evening show, museums, temples - along with the short Ross Island ferry on calm mornings. The water-based side is what gets cut back. Inter-island ferries run thinner, weather-dependent schedules, the Jolly Buoy and Red Skin national-park snorkel boats are closed June–October, scuba runs only on calm Havelock mornings, and the Baratang convoy and water sports pause on rough or stormy days.
Scuba is not banned in July, but it is limited. At Havelock (Swaraj Dweep) it runs only on calm early mornings when visibility allows, and it is cancelled on rough-sea days, so it is a maybe rather than a plan. The national-park snorkel boats to Jolly Buoy and Red Skin are fully closed June–October. If diving is the point of your trip, travel between November and April instead.
Yes. July is the peak of the south-west monsoon, with roughly 300–400 mm of rain spread over about 17 wet days, frequent heavy showers and thunderstorms, and high humidity. Rain usually comes in bursts rather than all day, so trips are still possible — but you should carry rain gear, keep electronics waterproofed and build flexibility into the plan.
The off-season months of June to September are the cheapest to visit Andaman, and July sits right in that window. Hotels, resorts and tour packages run well below peak-winter rates, and flights are typically much cheaper than in the December–January high season. The trade-off is monsoon weather, so the savings come with rough seas and reduced water activities.
Five nights and six days is a comfortable length, and in July it pays to weight those days toward Port Blair and the nearby islands rather than an ambitious multi-island route. Add a spare buffer day before your flight home in case a ferry is cancelled on rough seas. If you want to reach the far north, eight or more days gives the weather room to cooperate.
Port Blair is the most reliable base in July - its heritage sites and museums are all-weather, and Ross Island is a short hop away. Havelock (Swaraj Dweep) and Neil (Shaheed Dweep) are still beautiful and very green, but plan them with flexible dates because the ferries and water sports are weather-dependent. Save the far islands like Baratang for clear days.
Pack for warm, wet weather: a quick-dry rain jacket or poncho, a waterproof bag or pouch for phones and cameras, light breathable clothing, sandals with good grip for wet surfaces, and motion-sickness tablets for choppy ferry rides. Sunscreen still matters between showers, and a small umbrella plus a power bank are worth the space.
Yes, but on reduced, weather-dependent schedules. Government and private ferries between Port Blair, Havelock (Swaraj Dweep) and Neil (Shaheed Dweep) still run in the monsoon, though with fewer daily sailings than in peak season and the real chance of a cancellation on rough seas. Book ahead, check the day's status each morning, and keep a buffer day before your departure flight.
