Month-by-Month: Where to Dive in 2026-2027

Planning a dive trip is easy. Planning a dive trip at the right time for the right destination? That takes a calendar, some marine biology knowledge, and a healthy respect for monsoon patterns. We've done the homework so you don't have to.

Here's your month-by-month guide to the best liveaboard diving around the world. Bookmark this page — you'll come back to it.

January

Top picks: Maldives, Red Sea (Southern), Thailand (Similans)

January is peak season in some of the world's best destinations. The Maldives northeast monsoon is in full swing, bringing calm seas and crystal visibility. Thailand's Similan Islands are at their best. The southern Red Sea is cooler but uncrowded, with reliable shark action.

Maldives: Manta season is building. Visibility at its peak. Water temps around 28°C.
Similans: Season just opened. Whale sharks beginning to appear around Richelieu Rock.
Red Sea: The deep south routes (St. John's, Fury Shoals) offer exceptional reef diving with fewer boats.

February

Top picks: Maldives, Raja Ampat, Galápagos

February is arguably the finest month for the Maldives — manta encounters are at their most reliable, and conditions are near-perfect. Raja Ampat's dry season continues to deliver absurd biodiversity in calm waters.

Maldives: This is the month. Manta cleaning stations are buzzing, visibility is extraordinary.
Raja Ampat: Peak season. Expect wobbegong sharks, pygmy seahorses, and more nudibranch species than you can identify.
Galápagos: Warm season. Hammerheads are present, and water temps are at their most pleasant (around 24°C at the surface).

March

Top picks: Maldives, Red Sea (Northern), Galápagos, Raja Ampat

The sweet spot continues. March offers excellent conditions across multiple destinations, and it's the last month before Easter demand pushes prices up.

Red Sea (Northern): Spring conditions are ideal. The Brothers Islands start to heat up — literally and figuratively.
Galápagos: Marine iguanas are nesting, hammerheads are schooling, and sea lion pups are being adorably curious.
Maldives: Still prime. Book early — March is popular for good reason.

April

Top picks: Red Sea, Maldives (last chance), Indonesia (Komodo begins)

The Maldives season starts to wind down as the inter-monsoon transition approaches. But the Red Sea is entering its golden period, and Komodo season is just beginning.

Red Sea: Water warming up, visibility outstanding. The northern routes are divine.
Komodo: Season kicks off. Expect manta rays, colourful reefs, and those famous Komodo dragons on land.
Maldives: A gamble — could be perfect, could be the monsoon arriving early. Adventurous divers are rewarded with lower prices.

May

Top picks: Red Sea, Komodo, Galápagos

May is a transition month globally. Smart divers know this means fewer crowds and interesting conditions.

Red Sea: Building towards peak. Shark activity increasing at the offshore reefs. Warm water, clear skies.
Komodo: Conditions stabilising. Manta season in full swing at sites like Manta Alley and Cauldron.
Galápagos: The transition between warm and cold seasons brings nutrient-rich water and diverse encounters.

June

Top picks: Red Sea (peak), Indonesia (Komodo/Raja Ampat), Maldives (whale sharks)

Summer in the Northern Hemisphere means peak conditions in the Red Sea. It also marks the beginning of whale shark season in the Maldives' southwest monsoon.

Red Sea: This is it. The Brothers, Daedalus, and Elphinstone are firing on all cylinders. Hammerheads, oceanic whitetips, threshers.
Maldives (South Ari Atoll): Whale shark season begins. Crossings can be rough, but the rewards are immense.
Komodo: Mid-season excellence. Water temperatures dropping slightly, attracting mantas and pelagics.

July

Top picks: Red Sea, Galápagos (cold season begins), Indonesia

July delivers some of the year's most dramatic diving if you know where to go.

Red Sea: Peak continues. The deep south routes are at their finest. Warm water, big animals, long days.
Galápagos: Cold, nutrient-rich water arrives. Whale sharks at Darwin and Wolf — the main event. Water around 20-22°C, so bring a thick wetsuit.
Komodo: Current season. Experienced divers will love the channel dives with their manta aggregations.

August

Top picks: Galápagos (whale sharks), Red Sea, Maldives (whale sharks)

August is peak whale shark season in two of the world's best destinations simultaneously.

Galápagos: The holy grail month. Darwin's Arch delivers whale sharks with remarkable consistency. Hammerhead schools are massive.
Red Sea: Consistently excellent. The offshore reefs are at their most productive.
Maldives: Whale shark encounters in South Ari Atoll are frequent. Conditions are rougher but manageable.

September

Top picks: Red Sea (peak), Galápagos, Palau

September is the unsung hero of the dive calendar — peak conditions at several top destinations, but with noticeably fewer crowds than July-August.

Red Sea: Our favourite month for the BDE route. The water is warm, the sharks are bold, and the summer crowds have thinned.
Galápagos: Cold season continues. Whale sharks still present at Darwin and Wolf.
Palau: Dry season begins. Blue Corner is delivering wall-to-wall sharks and giant groupers.

October

Top picks: Red Sea, Palau, Raja Ampat (season begins), Thailand (Similans reopening)

October is a month of beginnings. New seasons opening, conditions peaking, and that gorgeous feeling of being first to dive a site that's been resting for months.

Red Sea: Many experienced divers consider October the single best month for the southern routes.
Raja Ampat: Dry season starts. Calm water, improving visibility, and the reefs have had months to recover from the wet season.
Thailand: The Similans reopen mid-October after their annual closure. Early season means pristine conditions and fewer boats.

November

Top picks: Red Sea, Maldives (new season), Thailand, Raja Ampat, Palau

November is a month of plenty. Multiple destinations are entering their prime, and competition for bookings often means better deals.

Maldives: The northeast monsoon returns, bringing calm seas and the start of manta season.
Thailand: Season fully underway. Manta rays starting to appear at Koh Bon.
Raja Ampat: Building towards peak. Conditions improving week by week.
Red Sea: Still excellent, especially the northern routes and wrecks. Water cooling but comfortably warm.

December

Top picks: Maldives, Thailand, Raja Ampat, Red Sea

December is premium season across the tropics. Conditions are excellent, but demand (and prices) are high. Book early for holiday period travel.

Maldives: Peak season beginning. Conditions near-perfect. Prices at their highest.
Thailand: Prime Similan season. Whale shark sightings increasing.
Raja Ampat: Approaching peak. Christmas/New Year trips sell out months in advance.

Planning Your Year

The smartest divers plan 6-12 months ahead, especially for peak season trips to popular destinations. Here's our suggested approach:

January: Book your autumn/winter trips while availability is wide open
March-April: Lock in summer and shoulder season trips
September: Start planning next year's adventures

The Bottom Line

Every month offers world-class diving somewhere on the planet. The trick is matching your available dates with the destination that's performing at its best. Shoulder seasons often deliver the best value — peak conditions with fewer crowds and lower prices.
