When to go to Mozambique: a month-by-month read on weather, water and wildlife

Short answer: May through October. Dry, mild, low humidity, water flat enough for a charter flight to land on schedule and a dhow to sail without anyone getting wet. That's when most of our Mozambique trips go.

The longer answer is more interesting, because Mozambique has two coastlines that don't quite behave the same way, and what's happening in the water often matters more than what's happening on land. The whale sharks, the mantas, the humpbacks, the turtles. They all keep their own diary. Sometimes the best month for one is the worst month for another. Below is the month-by-month we use when we plan a Mozambique trip, the version we'd write down for you if you asked us in person.

In short

• Best overall window: May to October. Dry, cool, calm.
• Best for whale sharks: October to March (peak), with sightings off Tofo year-round.
• Best for humpback whales: June to October.
• Best for manta rays: Year-round at Manta Reef off Tofo, with the dry-season months giving the cleanest visibility.
• When to avoid: January and February in the north. Cyclone risk peaks. Lodges close at short notice.

The two seasons

Mozambique runs on a wet season and a dry season. The dry season is May to October. The days are warm without being heavy, the nights are cool enough that you'll want a layer for the boat at dawn, the humidity drops, and the water is calm enough that the light aircraft and the sailing transfers run on time almost every day. That is the season we plan most trips for.

The wet season is November to April. The days are hot, the humidity is heavy, the afternoon thunderstorms roll in off the Indian Ocean and break overhead like a tin roof, and the cyclone risk along the Quirimbas coast climbs sharply in January and February. Some northern lodges close entirely between mid-January and mid-March. The Bazaruto lodges further south stay open through the year, but they can lose days to weather.

Within those two broad seasons, each month has its own character. Some are obvious, some are not.

What does May look like?

May is the opening of the season, and it's one of our quiet favourites. The rains have stopped, the humidity has dropped overnight, the water has settled. The light has that early-dry-season cleanness that photographers come for. Lodges are quieter than they will be in July and August. Some of the staff are still rotating back from leave, so service has a slightly slower, slightly warmer feel. We've sent honeymooners in May for years and they come back surprised by how much of the coast they had to themselves.

What does June look like?

June is when the humpbacks start arriving. They come up from the Southern Ocean to calve in the warm shallows between June and October, and on a good morning you can hear them blow before you see them. Mornings are crisp, particularly on the southern coast where the trade winds pick up. You want a light jumper for the boat at dawn. The diving and snorkelling come into their own. Reef visibility is at its best.

What does July and August look like?

The peak months for southern hemisphere travel. The lodges fill. Prices are at their highest. The weather is at its most reliable: dry, sunny, calm. Humpbacks are in the water. Manta rays are at the cleaning stations off Tofo. If you want guaranteed conditions and you don't mind sharing the bar with other guests, this is the safe choice. Book early. We're placing July and August clients eight to twelve months ahead, longer for the smaller lodges.

What does September look like?

September is the month we recommend most often to repeat travellers. The water warms back up, the whales are still around, the humidity is still low, the crowds of July and August have thinned, the staff have settled back into their stride. Reef visibility is excellent. If we had to pick one month to go to Mozambique ourselves, this is usually the one.

What does October look like?

October is the bridge. The dry season is closing, the heat is starting to build, and the whale sharks begin to arrive in numbers at Tofo. If marine megafauna is the reason for the trip, October is a strong choice. It's also the month where the coast feels its most generous. The water is warm enough to swim without thinking, the days are long, and the lodges still have their dry-season service in place. Sundowners on the deck run an hour longer than they should.

What does November look like?

November is the start of the wet season. The afternoon thunderstorms become a feature, particularly in the north, but the mornings are usually clear and warm. The whale sharks are now in residence at Tofo, and the diving is excellent. We send people in November when the value matters and the schedule is flexible enough to absorb a lost afternoon. We don't send first-time bush-and-beach clients in November, because the trip needs a margin for weather that a first-timer doesn't always have.

What about December?

December is hot, humid, and busy with festive-season travel. Lodges that stay open are often full. The whale sharks are reliable. The thunderstorms are heavier and louder. Cyclone risk in the north is rising. If you want a Christmas-and-New-Year coastal trip and you're happy for the weather to be part of the experience, December can be wonderful. If you want predictability, it isn't the month.

What about January and February?

These are the months we avoid for first-time trips, especially in the north. Cyclone risk peaks. Several Quirimbas lodges close entirely for safety and staff rotation. Heavy rain can ground charter flights for hours or for days. The southern coast around Bazaruto stays operational but can still lose days to weather. We do still build trips in this window for clients who specifically want it (divers chasing peak whale shark season at Tofo, mainly), but we build a longer buffer into the schedule and we're explicit about the risk before anyone pays a deposit.

What does March look like?

March is the tail of the wet season. Conditions improve through the month. The whale sharks are still at Tofo. Cyclone risk drops sharply by the end of March. Lodges that closed for the wet season start to reopen. It can be excellent value if you book the back half of the month and you're willing to accept that the trip is shoulder, not peak.

What does April look like?

April is the underrated one. The rains are mostly gone, the humidity is dropping, the water is still warm from the wet season, and the lodges are not yet full. Easter brings a small bump in occupancy. Otherwise, the coast feels quiet. We've placed honeymooners in late April for years, and they come back saying it was the trip nobody told them to take.

How does this differ by region?

The patterns above apply broadly to the whole coast, but there are regional differences worth knowing.

Bazaruto and the south. Lower cyclone risk. Lodges stay open year-round. The May-to-October window is reliable, and the shoulder months can offer real value.

Quirimbas and the north. Higher cyclone risk in January and February. Several lodges close for the wet season. The dry season is at its best in our experience here, with cleaner water and lighter humidity than the south. May through October is the safe window. We rarely send first-timers north of Pemba between mid-December and mid-March.

Tofo and the southern mainland. The marine calendar is more pronounced here than anywhere else on the coast. Whale sharks peak from October to March. Manta rays are year-round at Manta Reef. If marine wildlife is the main reason for the trip, the wet season delivers. You just have to accept the trade-off and bring a dry bag for your phone.

How we'd build it

For a first-time client, we recommend May, June, September or October. Those months offer the best chance of perfect weather and full lodge service, without the peak prices of July and August. They are the months we'd book for our own family if we were going.

For a returning client or a honeymoon, late April or early May, or the whole of September. Quiet, generous, water in great shape, staff with time to be properly welcoming.

For a diver focused on whale sharks, October or March, with a small contingency built into the schedule. Don't fly home on the last morning of the trip.

Whatever the month, we'd usually pair the coast with a safari rather than sending people straight in. Bush then beach. The order matters, and we go into why in our companion piece on Bazaruto vs Quirimbas.

FAQs

What is the cyclone season in Mozambique?

The cyclone season runs roughly from November to April, with the highest risk in January and February. Most cyclones make landfall in the central and northern parts of the country. The Quirimbas coast is more exposed than the Bazaruto coast.

Can you swim with whale sharks year-round?

Whale sharks are present at Tofo year-round, but sightings peak between October and March. Boat-based snorkelling trips with whale sharks are part of most Tofo lodge stays.

When do humpback whales arrive in Mozambique?

Humpbacks arrive from the Southern Ocean from June and stay through October to calve in the warm shallows. They are visible from boats and sometimes from the lodge decks themselves.

Is the water always warm enough to swim?

Yes. The water stays warm year-round. It's comfortable for swimming every month, including the southern winter.

Are lodges open year-round?

Bazaruto lodges generally stay open year-round. Several Quirimbas lodges close for parts of the wet season, typically January to March. We confirm closure dates lodge-by-lodge at the planning stage.

When is the best time to visit for the best value?

April and November offer the best balance of decent weather and softer pricing. Quiet, often warm, and the lodges are pleased to see you.

What about combining the coast with a safari?

The bush-and-beach pairing only really works in the months when both ends of the trip behave. May to October is the easiest window. We cover the archipelago choice in our companion piece on Bazaruto vs Quirimbas.

Sian Loehrer is co-founder of Marula Hill Travel. We plan boutique safaris across South Africa, Botswana, Zambia, Zimbabwe, Kenya, Tanzania, Rwanda, Uganda, Namibia, and Mozambique. We work only with lodges we know personally or through trusted partners.
