Overview of Toamasina’s Spring Climate
Toamasina sits on Madagascar’s east coast and gets steady warmth, high humidity, and more rainfall as spring goes on.
The Indian Ocean really shapes the local weather, influencing both temperature and rainfall.
Location and Regional Context
You’ll find Toamasina in the Atsinanana region, right on Madagascar’s eastern shoreline.
The city sits low, just about 12 meters above sea level, bordered by the Indian Ocean.
This coastal setting brings humidity and exposes Toamasina to moist trade winds from the east.
Around the city, the landscape stays mostly flat, with grassland, water, and patches of forest.
Within 80 kilometers, the land rises quickly toward Madagascar’s central highlands.
These inland mountains block and redirect airflow, which helps bring heavy rainfall to the coast.
Toamasina serves as a key port city. The ocean and land interact constantly, with sea breezes moderating heat and fueling moisture.
This blend of geography and ocean influence defines the spring climate here.
Climate Classification
The Köppen-Geiger system puts Toamasina in the Af classification, meaning it has a tropical rainforest climate.
This climate brings warm weather all year and no real dry season.
Even the driest months deliver plenty of rain.
Average temperatures stick close to 24–27°C (75–81°F) year-round.
In spring, highs hit 25°C to 29°C, while lows rise from 18°C to 22°C.
Nights stay warm and humid, so don’t expect much relief from the daytime heat.
Rain falls often and picks up as spring goes on.
September might be a bit drier, but by November, rain gets heavier and more regular.
Cloud cover changes fast too, with skies growing more overcast as spring moves forward.
This steady warmth, high humidity, and rainfall are classic signs of a rainforest climate.
Spring Months in Toamasina
Spring in Toamasina runs from September to November.
During this time, temperatures climb, and humidity rises from about 55% to nearly 99%.
The air feels muggier as the weeks pass.
Rainfall also ramps up quickly.
Early September averages around 25 mm over a 31-day span, but by late November, totals often jump past 90 mm.
Wet days get more common, going from about a 16% chance in early spring to nearly 40% by the end.
Daylight stretches out, from about 11 hours and 45 minutes in early September to over 13 hours by late November.
Sunrises come earlier, and sunsets slowly drift later.
This change in daylight, plus warmer seas offshore, helps heat and moisture build up fast across the region.
Average Temperatures During Spring
Spring in Toamasina brings a steady warming trend, with mild nights and warm afternoons.
Temperatures rise gradually, making it comfortable for most outdoor activities, though it signals the start of wetter, more humid weather.
Daytime and Nighttime Temperature Ranges
During spring, daytime highs usually land between 25 °C and 29 °C (77 °F to 84 °F).
Afternoons feel warm, but rarely get scorching, so the coastal climate is easier to handle than inland Madagascar.
At night, things cool off but stay mild.
Lows typically fall between 18 °C and 22 °C (64 °F to 72 °F).
Even in the coolest stretch, nights rarely dip below 16 °C (61 °F).
You’ll notice a nice balance between warm days and comfortable nights.
The ocean helps keep both day and night temperatures pretty steady.
Monthly Temperature Trends

- November: Highs about 29 °C, lows around 22 °C.
The climb is slow and steady, no big jumps.
By late November, days feel warmer, and nights get noticeably more humid.
This warming matches the increase in rainfall and cloud cover, which builds from September into November.
Comparisons With Other Seasons
Spring in Toamasina sits between the cooler, drier winter and the hotter, wetter summer.
Winter brings daily highs closer to 23–25 °C, and nights can drop to 17–18 °C, making it the coolest time of year.

Highs often reach 30 °C, and lows stay above 24 °C.
Humidity peaks then, making it feel even hotter.
Spring feels like a transition.
You notice the warming from winter, but you don’t get the intense heat and heavy rain of summer.
It’s honestly one of the more balanced times to experience Toamasina’s climate.

Warm water makes snorkeling and casual diving enjoyable too. Rainfall sometimes stirs up sediment, so visibility changes, but when the skies clear, the sea feels inviting and calm.
If you love spending long hours in the ocean, you’ll find these conditions pretty ideal. Unlike cooler coastal spots, you won’t need thermal gear, and even after sunset, the water stays comfortable.
Just keep an eye on local currents, especially after heavy rain, since they can get stronger. Safety first, right?
Influence on Local Weather
Warm sea surface temperatures directly shape Toamasina’s spring climate. The ocean adds extra moisture to the air, which explains why the city sees frequent rainfall, even in drier months.
You often get humid days along the coast because of this. Afternoon showers or quick storms pop up a lot, fueled by all that evaporation from the Indian Ocean.
The sea keeps temperatures from swinging too much. While inland areas might feel hotter during the day and cooler at night, coastal Toamasina stays more balanced.
This makes the city’s climate feel steady, with fewer wild shifts from day to day.
Wind Speed and Other Weather Factors
Spring in Toamasina brings a mix of steady breezes, high humidity, and plenty of clouds. You’ll notice moderate winds that affect daily comfort, plus warm temperatures and a lot of moisture in the air.
Average Wind Speed
During spring, Toamasina usually gets wind speeds between 7 to 11 mph (11 to 18 km/h). These breezes aren’t extreme, but they’re strong enough to shape your outdoor plans, especially if you’re near the coast.
The wind often feels refreshing, since daytime highs reach the upper 70s and low 80s °F. Travelers can enjoy beach walks or boat rides without heavy gusts getting in the way.
Wind speeds peak in the afternoon as land and sea temperatures shift. Nights calm down, making evenings more comfortable for eating outside or strolling around the city.
| Time of Day | Typical Wind Speed | Comfort Level |
|---|---|---|
| Morning | 6–8 mph | Light breeze |
| Afternoon | 9–11 mph | Moderate wind |
| Evening | 5–7 mph | Gentle breeze |
Prevailing Wind Patterns
In spring, the prevailing winds in Toamasina mainly come from the east and southeast, thanks to the Indian Ocean. These winds push moisture inland, leading to the frequent clouds and rain you see this time of year.
You’ll probably notice stronger sea breezes right along the coast compared to the city center. The ocean surface heats up more slowly than land, so a pressure difference forms, and air moves from the sea toward shore.
These wind patterns show up year after year, so you can usually count on them. If you’re planning water activities like sailing or fishing, the easterly flow means you can expect calmer mornings and breezier afternoons.
Humidity and Atmospheric Conditions
Humidity in Toamasina stays pretty high in spring, often above 80%. That makes the air feel warmer than the thermometer says.
Clouds hang around a lot, so the environment can get heavy, especially around midday.
Rain falls often, with showers popping up on many days each month. Most downpours don’t last long, but they definitely add to the dampness.
Atmospheric pressure doesn’t change much, just shifts a bit when showers roll through. Sometimes, mist or light rain cuts visibility, especially early in the morning.
All these things—humidity, clouds, and steady breezes—come together to make Toamasina’s spring climate feel warm, damp, and breezy. It’s not really wild or extreme, just kind of persistently muggy.
