What do you want to see?
Each animal keeps its own calendar, and the best atoll changes with it. For the atolls themselves, see the Maldives diving guide.
| To see | Best months | Where |
|---|---|---|
| Manta rays, feeding | July to September | Baa Atoll (Hanifaru Bay) |
| Manta rays, cleaning stations | December to March, June to July | North Malé, Ari |
| Whale sharks | All year, peak June to October | South Ari |
| Tiger sharks | All year, clearest December to April | Fuvahmulah |
| Hammerheads | January to March | Rasdhoo Atoll |
| Thresher sharks | All year | Fuvahmulah |
Doing both? Hanifaru's mantas and South Ari's whale sharks overlap from July to September, and a central-to-north liveaboard can cover both.
The two seasons, and why the wet one is often better
The Maldives has two monsoons. The northeast monsoon (Iruvai) brings the dry season from December to March: calm seas, less rain and the best conditions in the northern and central atolls. The southwest monsoon (Hulhangu) runs from May to November, with more wind, rain and surface chop, but also the plankton-rich water that brings in the mantas and whale sharks.
| Season | Conditions | Best in |
|---|---|---|
| Dry, December to March | Calm seas, clear water | North Malé, Ari, Lhaviyani |
| Wet, May to November | More wind and rain, rich water | Baa, South Ari, the outer atolls |
April and November are transition months: unpredictable, sometimes excellent, harder to plan around.
The mantas aren't at Hanifaru because the weather is good. They're there because the plankton is.
Month by month
In short: August and September are the best months for mantas and whale sharks together; December to March bring the calmest seas and clearest reefs.
| Month | Conditions | Go for |
|---|---|---|
| January | Peak | Reef diving, cleaning-station mantas, hammerheads at Rasdhoo |
| February | Peak | As January; the hammerhead peak |
| March | Peak | Cleaning-station mantas; the hammerhead window ends |
| April | Shoulder | Unpredictable; local knowledge matters |
| May | Good | Whale sharks building; mantas at cleaning stations |
| June | Peak | Hanifaru opens; whale sharks strong |
| July | Peak | Hanifaru peak begins; whale sharks excellent |
| August | Peak | The best month for Hanifaru; whale sharks |
| September | Peak | Hanifaru strong and whale sharks: the best month for both |
| October | Peak | Hanifaru tapering; whale sharks still good |
| NovemberNow | Good | Fuvahmulah tiger sharks; changeable conditions |
| December | Good | Reef diving, cleaning-station mantas; visibility recovering |
Mantas, whale sharks and tiger sharks
Hanifaru Bay, Baa Atoll: June to November
On a good day, 50–200 mantas feed together in one small bay. The peak runs from July to September. June and October are still good, and November is the tail of the season. Only permitted operators may enter the bay, and it is snorkel-only: scuba is not allowed. Hanifaru Bay: manta season and how to get there
South Ari Atoll: whale sharks all year
Mostly juveniles, seen in the channel between the atoll and the open ocean often enough that whale shark trips run daily. Encounters peak from June to October and are recorded every month. The South Ari guide
Fuvahmulah: tiger sharks all year
An isolated atoll south of the main chain, where tiger sharks feed on tuna and encounters are planned rather than hoped for. December to April brings slightly better visibility and sea conditions. The Fuvahmulah guide
Liveaboard or resort?
December to March: both work. Calm seas let resort day boats reach most sites, though a liveaboard still gives you more dives and more sites a day.
May to November: a liveaboard is much better. The animals move atoll by atoll, and a boat can be wherever the aggregations are that week. A resort stays put.
Ready to look at boats?
Before you go
Water temperature
27–31 °C all year. A 3 mm shorty is the minimum; a full 3 mm suit is more comfortable for several dives a day, and recommended for deeper outer-atoll diving. What wetsuit you actually need
Visibility
20–30 m in the dry season. In the wet season, 10–15 m on plankton-rich days at Hanifaru and around the whale sharks.
When to book
Boats for Hanifaru sell out early, so book four to six months ahead for July to October. Whale shark boats fill up two to four months ahead.
Questions
What is the best month to dive the Maldives?
It depends on what you want to see. Mantas feeding at Hanifaru Bay: July to September. Whale sharks at South Ari: June to October. Reef diving and the best visibility: December to March. Mantas and whale sharks on one trip: September.
Is the wet season good for diving in the Maldives?
Yes, and often better for the big animals. The southwest monsoon (May to November) brings the plankton that feeds the mantas and whale sharks. The trade-off is lower visibility on productive days and more surface chop.
Can you see mantas and whale sharks on the same trip?
Yes. July to September works for both. A central-to-north liveaboard in August or September can cover Hanifaru Bay in Baa Atoll and the whale sharks of South Ari. These trips sell out months ahead.
How is the diving season different from the resort season?
Resorts fill over Christmas and New Year and through the dry season. The big-animal months, June to October, fall in the wet season and are often better value; a wet-season liveaboard gives the most diving for the money.
Is the Maldives good for diving all year?
Yes. South Ari's whale sharks and Fuvahmulah's tiger sharks are there all year; Hanifaru Bay has a set window. Plan around the animals you want rather than one season.
What is the water temperature in the Maldives?
27–31 °C all year, with little change between seasons. A 3 mm shorty is the minimum; a full 3 mm suit is more comfortable for several dives a day.
