If you’re planning a trip to the far north of Madagascar, you’ll find that the weather in Diego Suarez—locals call it Antsiranana—shapes your entire experience. The region stays warm all year, but the difference between dry and wet seasons really changes how comfortable you’ll feel and what you can do. You’ll have the best time visiting Diego Suarez during the dry season from May to October, when rain is rare, humidity drops, and it’s just easier to be outdoors.
These months bring steady sunshine, clear skies, and cooler evenings. Exploring the city or the surrounding landscapes feels much easier. Hiking in national parks, relaxing on beaches, or heading out for a boat trip all become more enjoyable without those heavy rains getting in the way.
Once the dry season ends, Diego Suarez turns wetter and more humid, especially from January through March. The scenery gets greener, sure, but travel becomes less predictable. Heavy rain can limit your outdoor adventures.
If you know how the seasons shift, you’ll find it much easier to balance comfort and adventure for your trip.

Rainfall and Precipitation Variations
Rain in Diego Suarez follows a pretty clear pattern. The rainy season hits from January to March, bringing frequent storms and totals that can go over 200 mm per month. January usually takes the prize as the wettest month, with about 20 rainy days.
From May to October, the dry season takes over. Rain almost disappears, and September often gets less than 10 mm for the whole month. This stretch is the safest bet for hiking, beach days, and other outdoor fun.
Rain usually comes in short bursts, not all-day downpours. So, even in wetter months, you might catch some sunny breaks.
Humidity and Wind Conditions
Humidity rises during the rainy season, making the air feel heavier. From May through October, humidity drops off, so walking, sightseeing, and water sports feel way more comfortable.
Diego Suarez also gets steady winds, especially in the Bay of Winds. These breezes get strongest in the dry season and are famous among windsurfers and kitesurfers.
Lower humidity and those cooling trade winds during the dry months help balance out the warmth, so even midday sun isn’t too overwhelming.
Dry Season Versus Wet Season: What to Expect
Weather in Diego Suarez, or Antsiranana, flips between a long dry period and a shorter, intense wet season. Each season brings different conditions that shape how you plan your days and what you can safely do.
Characteristics of the Dry Season
The dry season runs from May through November. Rainfall drops to almost nothing, and September often sees less than 10 mm. Skies stay mostly clear, and humidity falls compared to the rest of the year.
Daytime temperatures stick between 29°C and 31°C, while nights cool off to about 21°C to 23°C. Hiking, beach trips, and exploring national parks all feel easier.
Roads and trails stay in better shape, which means fewer travel headaches. You’ll also deal with fewer mosquitoes and less risk of waterborne illness.
Wet Season Weather Challenges
The wet season usually starts in December and lasts until March. Rainfall peaks in January, sometimes topping 250 mm in a month. Showers come often and can get heavy, sometimes lasting for hours.
Humidity climbs, and nights around 24°C can feel sticky. Outdoor adventures like trekking or wildlife spotting get tougher, and some roads may flood or turn to mud.
Tourism services stay open, but schedules might shift if the weather acts up. If you’re coming during these months, bring waterproof gear and be ready to change your plans if needed.
Cyclone Risk and Safety Considerations
Northern Madagascar, including Diego Suarez, faces a risk of tropical cyclones between January and March. Not every year brings a direct hit, but storms can deliver strong winds, heavy rain, and coastal flooding.
Cyclones can knock out electricity, water, and transport. Flights and ferries often get delayed or canceled during bad storms.
If you’re visiting then, keep an eye on local forecasts and follow safety advice from authorities. Picking a hotel with solid construction and an emergency plan is a smart move.
Best Months to Visit Diego Suarez Based on Weather
The climate in Diego Suarez, or Antsiranana, stays warm, but rainfall and humidity swing a lot. The dry months give you more chances to enjoy the outdoors. The wetter months can be tricky, but you’ll find fewer tourists around.
Ideal Months for Outdoor Activities
The dry season, from May to October, is definitely the best for outdoor plans. Rain is rare, and daytime highs sit between 29°C and 32°C. Nights cool down to 21°C to 23°C, which feels great after a hot afternoon.
You can hike in the nearby mountains, explore Diego Suarez Bay, or try out water sports without worrying about storms. Winds stay steady but not wild, so the air feels less humid and walking or cycling is more pleasant.
It’s also easier to plan day trips to national parks during these months, since trails stay dry and roads are open. If you want to be outside most of the time, this season offers the best mix of temperature and weather stability.
Shoulder Seasons: Pros and Cons
The shoulder months, April and November, appeal to travelers who want to skip the busy season. Rain is a bit more common than in the heart of the dry season, but nothing like January through March. You might get caught in a shower, but it usually passes quickly.
You’ll see fewer crowds at the main sights and find more available spots in hotels or guesthouses. Prices can drop a little too.
The downside? Humidity goes up a bit, and there’s a slightly higher risk that rain will mess with your outdoor plans. Daytime highs still push above 30°C, so the heat feels stronger when it’s muggy. If you don’t mind a little unpredictability, you can get a quieter experience in Antsiranana.
Activities and Experiences by Season
The dry months bring steady winds, cooler temperatures, and clear skies—perfect for outdoor adventures. The wetter months limit some activities, but you’ll find greener landscapes and sometimes better wildlife spotting.
Hiking and Nature Trails
You can hike all year, but May to October feels best. Trails stay dry, and temperatures let you walk longer without overheating. Many people tackle the climb to Montagne des Français for amazing views over Antsiranana Bay.
If you’re up for a drive, check out the limestone formations at Tsingy de Bemaraha or the rainforests in Andasibe—just go when it’s not pouring. These spots show off Madagascar’s unique geology and wildlife.
Shorter walks near Ramena Beach feel easier during the cooler months. Bring water and sunblock, since shade is rare along the coast. Hiring a local guide helps you find hidden viewpoints and keeps you from getting lost.
Water Sports: Kitesurfing and Fishing
From June to September, trade winds turn Diego Suarez into a kitesurfing hotspot. The bay by Ramena is a favorite, with shallow water for both beginners and pros. You’ll find rentals and lessons in town and at the beach.
Fishing is best in the dry season, when the sea calms down. Local operators run deep-sea trips for tuna, marlin, and dorado. Shore fishing near rocky points is popular, especially early in the morning.
During the wet season, January to March, winds die down and the sea can get rough, so kitesurfing takes a backseat. Sometimes, you can sneak in a short fishing trip between storms. Always check the weather before heading out.
Wildlife Watching Opportunities
Wildlife changes with the seasons. In the wet months, January through March, forests get lush and attract lemurs, reptiles, and birds that are harder to spot in the dry season. Andasibe is especially lively then, with active indri lemurs and colorful frogs.
Dry season means open landscapes, so you’ll spot bigger animals and nesting seabirds along the coast. Trips to Nosy Be or the mangroves near the bay often reveal sea turtles and wading birds.
Bring binoculars and aim for early morning or late afternoon. Animals are more active, and it’s cooler, so you’ll have better luck without waiting around all day.
Accommodation and Travel Tips for Each Season
Where you stay in Diego Suarez really depends on the season. Weather patterns affect what’s available and how much you’ll pay. Planning ahead saves you hassle and helps you find the right spot.
Hostels and Guesthouses Availability
In Antsiranana (Diego Suarez), hostels and guesthouses are your go-to budget options. During the dry season from May to October, these places fill up fast, since travelers come for snorkeling at Emerald Sea or hiking in Amber Mountain National Park.
Guesthouses near Ramena Beach and the downtown area get especially busy. You’ll see higher occupancy and less wiggle room for walk-ins.
In the wet season, January through March, demand drops. Most hostels stay open but with fewer guests, so you get more choices and lower prices. Some smaller places might close if rain makes the roads too rough.
Typical lodging includes:
- Budget hostels with shared dorms
- Family-run guesthouses with private rooms
- Beachfront stays near Ramena
Booking Advice for Peak and Off-Peak Periods
During the dry season, book at least a few weeks ahead, especially if you want air conditioning or a beach view. Mid-range guesthouses often ask for deposits to hold your spot.
In the rainy season, you can usually find a room when you arrive. Walk-in rates drop, and owners might give discounts to fill empty beds. Still, check ahead if you’re traveling during local holidays—domestic tourists can fill up the town too.
If you’re staying more than a week, talk directly to the guesthouse owner. Many will cut you a deal for a longer stay, especially outside peak months. It’s a good way to save money and settle in comfortably.
Getting Around Diego Suarez in Different Weather Conditions
Traveling around Diego Suarez depends a lot on the season. Rain and heat can affect both comfort and how easy it is to get from place to place. You’ll notice a big difference between the dry months and the rainy season.
Local Transport: Taxi and Tuk-Tuk
In Antsiranana (Diego Suarez), you’ll mostly spot taxis and tuk-tuks zipping around town. Taxis usually handle the longer hauls, while tuk-tuks make short city trips easy and cheap.
Both options cost a lot less than what you’d pay in bigger cities like Antananarivo. During the dry season, tuk-tuks give you a breezy, open-air ride—honestly, it feels great with that constant coastal wind.
But in the rainy months from January to March, tuk-tuks can get a bit tricky. Their open sides won’t keep you dry if a sudden downpour hits.
Taxis step up during wet weather, giving you shelter from sudden rain. They’re also handy if you have bags to lug around or you’re heading out at night, when the streets get slick.
It’s a good idea to settle on a fare before you hop in, since meters aren’t really a thing here.
Road Conditions and Accessibility
Road quality in Diego Suarez really depends on where you go. In Antsiranana, you’ll find that main streets are paved, so you can usually get around all year.
But once you turn off onto side roads or head out toward the beaches or national parks, things can get tricky after heavy rainfall. Locals deal with potholes, mud, and flooding all the time during the wet season.
From May to October, roads dry out and you’ll probably have an easier time getting around. Day trips outside the city actually become a lot more doable, so it’s a good window to hire a car or grab a taxi for longer adventures.
Thinking about venturing past the city? If you’re heading for remote bays or nature reserves, a 4×4 just makes sense. These things handle rough terrain way better, especially when the rain turns tracks into a mess.
Always ask around for local advice before you set off. Conditions can change fast out there, and it’s better to know than to get stuck.
