If you’re planning a trip to Madagascar’s east coast, you really need to pay attention to the weather. Toamasina, which is the country’s main port city, sits in a tropical zone where the seasons flip pretty dramatically between wet and dry.

The best time to visit Toamasina for comfortable weather is during the dry season, from May to October. Rainfall drops off, and temperatures stay warm but not unbearable.

During these months, you can actually get outside and do things without worrying about rain ruining your plans. The days are mostly sunny, humidity drops a bit, and highs usually hover between 25°C and 30°C.

Exploring the beaches, canals, or even the rainforests nearby feels a lot easier than in the soggier months.

Once you step outside this window, it gets hotter, stickier, and rain falls more often, especially from December through March. If you know these patterns, you can pick the right time for your visit, whether you want peaceful days on the coast or the lush green scenery after the rains.

Overview of Toamasina’s Climate

Toamasina sits on Madagascar’s east coast and lives with a tropical climate thanks to its spot by the sea and steady trade winds. Temperatures stay warm all year, and rain comes often, especially at the start of the year.

Humidity is always high, and the ocean stays warm enough for swimming no matter when you visit.

Geographical Influence on Weather

The city sits right at sea level along the Indian Ocean, and that shapes its weather in a big way. The southeast trade winds blow in steady moisture from the ocean, turning Toamasina into one of Madagascar’s wettest cities.

Rain falls every month here. Even in the driest stretch, from September to November, you’ll still see showers.

December through March brings the most rain, and sometimes tropical storms or cyclones show up.

The coast helps keep temperatures steady. Nights rarely drop below 15 °C, and daytime highs usually don’t go above 31 °C.

This mild swing makes the climate a bit more predictable than what you’d get inland.

Humidity? It’s almost always above 80%. If sticky air bothers you, try coming during the drier months for a bit of relief.

Köppen Climate Classification

Toamasina’s climate falls into the Af category in the Köppen system, which means it’s a tropical rainforest climate. There’s no real dry season, and every month gets more than 60 mm of rain.

The Af type means warm temperatures and heavy precipitation are the norm. Toamasina fits that mold, with annual rainfall topping 3,000 mm and lots of cloudy days.

There’s no sharp split between wet and dry seasons like you’d see in savanna or monsoon climates. October is the least rainy month, while March is usually the wettest.

For travelers, this means high humidity, thick greenery, and regular showers. Rain gear? You’ll probably want it any time of year.

Annual Temperature Patterns

Temperatures in Toamasina barely budge throughout the year. The average annual temperature sits around 24–25 °C.

February is usually the warmest at about 27 °C, and July cools off the most, around 21 °C.

Daily highs generally range from 25–31 °C, and nighttime lows stick between 17–23 °C. There’s not much difference from one season to the next.

Here’s a quick look at the averages in °C:

Month Min Max Mean
Jan 23 31 27
Apr 22 30 26
Jul 17 25 21
Oct 19 28 23

Sea temperatures are always inviting, from about 24 °C in August–September up to almost 29 °C in January–March. Swimming’s an option all year, though heavy rain might mess up the beach.

Since the temperature doesn’t swing much, what really sets each season apart is the rain. You’ll spot the wettest, stormiest months early in the year, and things calm down a lot in early spring.

Recommended Months for Travel

You get the most reliable weather from May through November. In these months, daily temperatures usually land between 20°C and 29°C (68°F to 84°F).

Rain falls less often, with 8–12 rainy days per month instead of the heavy downpours you’ll see between January and April.

September, October, and November are the driest. The skies are sunniest, and storms are rare, so most travelers pick these months.

If you’d rather have cooler weather, June to August is a good pick. It’s still warm, but not too hot, and it’s less crowded, so you can explore at your own pace.

Weather Highlights During Peak Months

From September to November, you’ll see plenty of sunshine and light breezes. Highs average 27°C to 29°C (81°F to 84°F), and nights cool down to a comfortable 20°C to 22°C (68°F to 72°F).

Rain barely shows up, and when it does, it’s usually quick. Sunshine lasts 7–8 hours a day, giving you lots of time to enjoy the coast and other spots without worrying about the weather.

Humidity sticks around because, well, it’s the tropics—but it’s more tolerable than in the wetter months. Gentle ocean winds help with the heat and make it perfect for beach days, snorkeling, or surfing.

Tourist Preferences and Comfort

Most people plan their trips during the September to November peak season because the weather is warm and steady. These months also offer the best conditions for outdoor sightseeing, without the heavy rains or cyclone threats that show up earlier in the year.

If you want fewer crowds, May to August could be your sweet spot. The weather is still great—lower rainfall, steady sunshine, and moderate temps—just with a bit more breathing room.

No matter when you visit, don’t forget about the strong UV levels. Sunscreen, hats, and light protective clothes will help you stay comfy while exploring Toamasina’s beaches, markets, and sights.

You’ll want to plan for wet weather no matter when you visit. Still, late winter and spring tend to be less rainy, so outdoor activities get a little easier.

Humidity Fluctuations

Humidity in Toamasina stays high all year, usually sitting between 82% and 85%. That much moisture makes things feel muggy, especially during the hotter stretch from December to March.

Even in the cooler months from June to September, the humidity doesn’t really let up. It feels a bit more tolerable thanks to lower temperatures, but you’ll still notice the dampness, especially in the mornings and evenings.

Since rain and humidity both stay high, you can count on a humid climate year-round. Light, breathable clothes and plenty of water will help you stay comfortable while you’re here.

Rainfall Patterns and Humidity Levels

Toamasina’s tropical climate keeps rainfall frequent and humidity high. You’ll spot clear differences between the rainiest months and the slightly drier spells, and that can definitely shape your outdoor plans and comfort.

Wettest and Driest Months

Rain comes down hard throughout the year, but it really peaks in the first few months. March stands out as the wettest month, with an average of 455 mm over 20 days. January and February aren’t far behind, each with more than 400 mm of rain.

September, October, and November bring the driest stretch. October is the driest, with rainfall dropping to about 99 mm over 12 days. That’s still a decent amount compared to many places, but it’s the best bet for drier weather.

The city usually clocks in nearly 3,200 mm of rain each year, spread across about 199 days. Even during the so-called drier months, quick showers can still pop up, thanks to the southeast trade winds.

If you’d rather skip the heaviest rains, it makes sense to avoid January through March.

Impact of Humidity on Comfort

Humidity rarely lets up in Toamasina, often hovering between 82% and 85%. That kind of moisture makes the heat hit harder, especially when daily highs reach around 30°C in the wettest months.

You’ll probably find mornings and evenings a bit more comfortable, while midday can get downright sticky. Even when things cool off from June to September, with average temperatures dropping to 21–23°C, you’ll still notice the humidity.

High humidity slows down sweat evaporation, so lightweight clothes and breaks in the shade really help. If you’re planning outdoor activities, the cooler, less rainy months from June to September might be your best bet, though you’ll still get that tropical vibe.

Sunshine Hours and Daylight

Sunshine and daylight in Toamasina shift with the seasons. These changes affect how much time you’ll get for things like sightseeing or hitting the beach.

Monthly Sunshine Duration

Sunshine doesn’t spread evenly through the year here. Toamasina averages between 5 and 9 hours of sunshine a day, depending on the month.

You’ll see the least sunshine in July, with around 5.3 hours daily. That’s mostly because of shorter days and more clouds. On the flip side, November and December bring longer sunny stretches, with up to 7.9 to 9.3 hours each day.

Here’s a quick look at average daily sunshine:

Month Avg. Sunshine (hrs/day)
Jan ~6.5
Apr ~6.0
Jul ~5.3
Nov ~7.9
Dec ~9.3

If you’re after consistent sunlight for your plans, late spring to early summer (Oct–Dec) gives you the best shot.

Daylight Variation Throughout the Year

Daylight in Toamasina shifts with the seasons, but honestly, the changes aren’t that dramatic if you compare them to what people experience further from the equator.

In June and July, days feel shortest, hovering at around 11 hours.

When the calendar moves closer to December, daylight stretches out to about 13.2 hours. That extra time really lets you squeeze in more outdoor moments, even if the rain tries to crash your plans.

Toamasina’s tropical spot keeps things pretty steady. You’ll never drop below 11 hours of daylight, so even when it cools off a bit, there’s still plenty of time to wander markets or stroll along the beach without any real rush.
