Nosy Be welcomes travellers with a classic tropical climate, giving the island a feeling of eternal summer. The weather here is remarkably stable: there are no sharp temperature changes, and the air remains comfortably warm throughout the year. Thanks to this, the island is considered a wonderful destination for a beach holiday in almost any season.

The year is roughly divided into two periods. From November to April, hotter and more humid weather reigns on the island: the average temperature hovers around 27°C, and the number of rainy days increases noticeably. From May to October, a drier season sets in, when rains are less frequent and the heat subsides slightly to a pleasant 24–25°C, creating ideal conditions for those who do not tolerate high humidity well.

A notable feature of the local climate is that even in the "coolest" months, such as July and August, Nosy Be retains a truly summer atmosphere. Precipitation in the high season often takes the form of short tropical downpours that are quickly replaced by sunshine, so they rarely interfere with a full holiday.

The climate in Nosy Be is characterized by enviable stability: eternal summer reigns here with minimal temperature fluctuations throughout the year. According to statistics, the warmest month is April, when average figures reach 27.4°C, and the daily maximum can rise to 29.1°C. The period from November to May is generally characterized by higher temperatures, holding at around 27°C, which creates ideal conditions for heat lovers.

The nominal "winter," which falls in July and August in the Southern Hemisphere, brings only slight coolness. In these months, the average temperature drops only to 24.6–24.7°C. Even in the coldest time of the year, minimum night temperatures do not fall below 23°C, so the weather feels very mild and comfortable, without sharp cold spells.

A feature of the temperature regime of Madagascar in this region is the very small amplitude between day and night figures. The difference between the daily maximum and minimum is only about 3–3.5 degrees. This ensures a steady thermal background around the clock: nights here are as warm and velvety as the days, allowing you to enjoy outdoor recreation at any time.

Precipitation on the island of Nosy Be is distributed unevenly throughout the year, forming two distinct seasons. The wettest period lasts from November to March. The peak of rainy weather falls in January, when the highest number of rainy days is recorded — about 28, and the average level of moisture reaches its annual maximum.

The dry season begins in May and continues until September. This time is considered the most favourable for a beach holiday, as the likelihood of getting caught in the rain is significantly reduced. The driest month is July: at this time, precipitation falls rarely (on average only 7 rainy days), and the total amount is minimal — about 1 mm.

In the transition months, such as April and October, the weather gradually changes. Despite the high frequency of rains in the wet season, statistics show that the total volume of precipitation remains relatively moderate. This suggests that rains in Nosy Be, although they may occur frequently, are likely to be short-term tropical downpours that are quickly replaced by the sun.

Nosy Be delights travellers with a warm tropical climate all year round, so the basis of your wardrobe should consist of light clothes made from natural breathable fabrics such as cotton and linen. T-shirts, shorts, loose shirts, and summer dresses will be appropriate in any month, as the average air temperature remains steadily in the comfortable range of +24°C to +27°C. Be sure to bring a wide-brimmed hat to protect yourself from the strong sun, which shines brightly here even on cloudy days.

When planning your trip, it is important to consider the seasonality of rainfall. From November to March, the island experiences a wet season when rains occur very frequently, so a light raincoat, a waterproof windbreaker, and an umbrella will become your best friends. In the period from May to October, which is considered the drier season, there is significantly less precipitation; however, a light long-sleeved sweater will still be useful for protection against mosquitoes in the evenings or in case of a fresh sea breeze.

As for footwear, flip-flops or sandals are perfect for a beach holiday, while comfortable, closed, and breathable trainers are better for excursions and walks around natural attractions. Don't forget to pack high-factor sunscreen, quality sunglasses, and insect repellent in your suitcase to make your holiday in this picturesque corner of Madagascar as comfortable as possible.
