Introduction
Madagascar is a large island located in the Indian Ocean, and has a
tropical climate, rainy along the east coast, arid in the south-west, and temperate in the mountains. In inland areas, mountain ranges mitigate the climate, while rainfall varies depending on slope exposure. Being in the Southern Hemisphere, the country has reversed seasons compared with Europe or North America.
In the whole country, there's a
rainy season from November to March, which, however, produces little effects in the southwest, which is therefore arid. On the other hand, in most of the country, there is a
dry season from April to October (or from May to September in the north), except on the east coast, where it rains all year round. As is typical of tropical areas, the rains usually occur in the form of thunderstorms, especially in the afternoon, so there's no shortage of sunshine even in the wettest months, at least in the morning hours.
In the cool period, from mid-May to September, but sometimes also in October, cool air masses from the south-west can affect the country, bringing a bit of cool weather at night, especially in the center-south, and even cold in inland areas.
The country is very interesting, not only for the beauty of the landscapes, but also for its flora and fauna. In fact, having been separated from the African continent millions of years ago, it has a great biodiversity and many native species.
The far north
In the far north, in the northern tip of Madagascar, it is hot all year round, while the rains are quite contained, hovering around 1,000/1,200 millimeters (40/47 inches) per year.
Antsiranana
In
Antsiranana (or Diego-Suarez), it is hot all year round, although the temperatures slightly drop from June to September. Here are the average temperatures.

North-west coast
On the north-west coast too, temperatures are high all year round, but being that it's directly exposed to the northwest monsoon, the rains are more abundant, so much so that they exceed 2,000 mm (80 in) in some areas.
Nosy-Be
In
Nosy-Be, an island located a short distance from the coast of Ambanja, the decrease in temperatures from May to August is limited. Here are the average temperatures.

Not only the period from
November to March is rainy, but it's also hot and muggy. We are in the
austral summer, a season when the country is divided into two: in the north, the north-west monsoon prevails, bringing heavy rains along the north-west coast, where rainfall is around 400/500 mm (16/20 in) per month in January and February. Here is the average rainfall of Nosy-Be.

Furthermore, the west coast is not as rainy as the north-west coast, in fact, the rainfall hovers between 700 and 1,000 mm (27 and 40 in) per year, compared with the 1,500/2,000 mm (60/80 in) of the northwest coast.

Near Morondava, we find the famous Avenue of the Baobabs.
Arid south-west
On the south-western coast, rainfall diminish further, so much so that it drops below 500 mm (20 in) per year. In fact, in the austral summer, the south-east trade winds still blow in the south of the country, bringing rainfall along the eastern side, but it is much less intense in the south-west.
In winter, on the other hand, temperatures drop quite sharply, especially at night, when it gets cool, also because from June to September, and sometimes even in May and October, this area is directly exposed to cool air masses that may come from South Africa.
Toliara
In
Toliara (formerly Tulear), just north of the Tropic of Cancer, only 420 mm (16.5 in) of rain fall per year, with a maximum of around 90 mm (3.5 in) per month from December to February. Here is the average precipitation.

East Coast
As mentioned, during winter, the south-east
trade winds prevail, and they are cool and dry everywhere except along the
east coast, where they release the moisture which they have previously picked up over the ocean. For this reason, on the east coast and on the first slopes near the coast, it rains throughout the year, and a tropical forest flourishes there.
Toamasina
In
Toamasina (formerly Tamatave), 3,350 millimeters (132 inches) of rain fall per year. In March, which is the rainiest month, rainfall exceeds 400 mm (16 in). The only period when the rains are not too heavy is from September to November, and this is true in general for the entire east coast.
Here is the average precipitation of Toamasina.

On the east coast, the sun does not shine very often, since the rains are frequent all year round. However, the sunniest season is the winter, from May to August, when the trade winds directly hit the coast, while the sunniest months (albeit slightly) are October and November.

The temperature of the sea on the east coast is high enough for swimming all year round, although it decreases a bit from July to October, as we can see in the following table.

To the north of Toamasina, we find an island,
Sainte-Marie, otherwise called Nosy Boraha, which is located in this very rainy area and is covered by forests. Between July and September, the humpback whales that come from the Antarctic seas and congregate for breeding in the channel between the island of Sainte-Marie and the coast of Madagascar, are often observed in a rainy context. Near Île Sainte-Marie, there is another smaller island, Île aux Nattes (or Nosy Nato).
Along the east coast to the south of Toamasina, precipitation decreases gradually, even though the trend is similar, with rains distributed throughout the year, and a relative minimum in September and October. So, rainfall amounts to 2,500 mm (98 in) in
Mahanoro and to 2,100 mm (83 in) in
Manakara.
Tolanaro
In the southernmost part of the east coast, in
Tolanaro (or Fort Dauphin), rainfall drops to 1,700 mm (67 in) per year; it remains below 200 mm (8 in) in every month, and drops to 75/100 mm (3/4 in) per month from August to October. Here is the average rainfall.

Inland areas
As mentioned, the climate in the
interior of the country is tempered by altitude, at least at intermediate elevations, while above 2,000 meters (6,500 feet), the temperature during winter can drop below freezing (0 °C or 32 °F), especially in the south. In the dry season, a wind that is able to raise dust from the parched ground can sometimes blow on the plateau. On the other hand, in the rainy season, the rains can make it difficult to get around on unpaved roads.
In the interior, there are also mountains. The highest mountain is
Maromokotro, 2,876 meters (9,436 feet), located in the north of the island, in the Tsaratanana Massif. On the other hand, in the south, to the south of Fianarantsoa, in the Andringitra National Park, the highest mountains reach around 2,500 meters (8,200 feet).
Antananarivo
The capital,
Antananarivo (formerly Tananarive), is located at 1,300 meters (4,300 feet) above sea level, and has a pleasant climate, in fact, the average ranges from 22 °C (71.5 °F) in the summer months to 15 °C (59 °F) in July. Winter is therefore pretty cool. Here, the best months are April, September and October.

Further south, in
Fianarantsoa, at 1,200 meters (3,900 feet), the climate is similar to that of Antananarivo.
Tropical cyclones
In the warm season, Madagascar may be affected by
tropical cyclones, which can form in the South-West Indian Ocean from November to mid-May, although they are more likely from late December to mid-April.
Some intense cyclones that hit Madagascar were Gafilo in March 2004, Giovanna in February 2012, Enawo in March 2017, and Idai in march 2019.
