Weather in Mossoró

Stay informed about the current weather conditions in Mossoró to ensure your trip is as comfortable as possible. Below, you will find up-to-date data, detailed forecasts, and useful charts.

The climate of Mossoró can be described as hot semi-arid tropical. The city is renowned for its abundance of sunlight and high temperatures throughout the year, creating an atmosphere of eternal summer. It practically never gets cold here, and even during the "coolest" months, the weather remains very warm, making the region attractive for those who love the heat.

There are two distinct seasons during the year, depending on rainfall. The period from February to May is considered the rainy season: during this time, especially in March and April, the highest number of wet days is observed, although air temperatures remain high. The second half of the year, starting from August through December, represents the dry season. In these months, rain falls extremely rarely or not at all, and the sky delights with impeccable blueness.

The temperature regime in Mossoró is notably stable. Average figures hover around 27–29°C; however, in the dry season, particularly in October and November, the daytime heat intensifies, and the thermometer can rise to 34–35°C. Travellers should take this feature into account and stock up on sun protection, regardless of the chosen time for the trip.

Mossoró is distinguished by a consistently hot climate throughout the year, making it a destination for lovers of warmth and sun. The annual temperature range here is small: average figures fluctuate from 27.4°C to 29.5°C. The hottest months are traditionally October and November, when daytime highs reach the 34-35°C mark. At this time of year, the sun is particularly active, and the heat is felt most intensely.

The concepts of "winter" and "summer" are quite relative here due to the proximity to the equator. The Brazilian summer (from December to February) is characterized by high temperatures with an average value of about 29°C and warm nights (about 24-25°C). The "winter" period, falling on June, July, and August, brings only a minimal drop in temperature. During the day, the air still warms up to 32°C and above, however, the nights become slightly fresher and more comfortable, cooling down to 22-23°C, which allows for a break from the daytime heat.

A characteristic feature of the Mossoró climate is the noticeable temperature difference between day and night, which averages about 10-11 degrees. For example, in August or September, after a scorching afternoon with temperatures near 34°C, evening coolness sets in with figures around 23°C. This creates favourable conditions for evening walks, although light summer clothing remains relevant at any time of day and in any season.

Precipitation in Mossoró has a clearly defined seasonal character, distinctly dividing the year into wet and dry periods. The rainiest time falls on the first half of the year, reaching its peak in March, when about 25 days with precipitation are recorded. February and April are also distinguished by increased humidity, so travellers planning a trip during these months should be prepared for frequent rains.

The second half of the year, conversely, is characterized by exceptional dryness. From August to October, the probability of precipitation drops to zero: statistics show an absence of rainy days during this period. This time is ideal for those who prefer guaranteed clear weather and want to avoid the need to carry an umbrella.

Transitional months, such as June, July, and December, bring only rare and insignificant precipitation. It is worth noting that even in the rainy season, the total amount of precipitation in millimetres remains moderate, which often indicates the short-term nature of the downpours. Thanks to the hot climate of Brazil, there is never cold precipitation or snow here — only warm tropical rains.

Since Mossoró is distinguished by a hot climate year-round with an average temperature of about +28–30°C, the basis of your luggage should be light summer clothing. Give preference to items made from natural breathable fabrics, such as cotton and linen, to comfortably endure the Brazilian heat. Shorts, T-shirts, loose trousers, and open shoes will become your main companions. Do not forget a wide-brimmed hat and quality sunglasses, as the sun is very active here.

When planning a trip, it is important to consider the rainy season, which lasts from February to May. During this period, precipitation falls often, so a light raincoat or a compact umbrella will be simply necessary, and it is better to choose quick-drying and non-slip footwear. In the dry season, especially from August to November, there is practically no rain, but the sun becomes even more intense, so it is worth stocking up on sunscreen with a high protection factor (SPF 50+) and skin moisturizers.

For long walks around the city, be sure to take comfortable, worn-in shoes, such as trainers or sandals with good foot support. Although nights in Mossoró are warm and the temperature rarely drops below +23°C, one light jumper or long-sleeved shirt will not go amiss: it will come in handy for protection against insects in the evenings or from the cool air in premises where powerful air conditioners are working.
