Weather in Fortaleza

Planning a trip to Fortaleza? Here you will find the most up-to-date weather information, including forecasts and useful charts, to make your journey as comfortable as possible.

Fortaleza is characterised by a typical tropical climate. This means it is warm here all year round, with average air temperatures hovering around 27°C. The difference between day and night temperatures, as well as between the hottest and "coolest" months, is minimal, ensuring consistently comfortable conditions for lovers of warm weather.

Two main seasons are clearly distinguishable in Fortaleza's climate: wet and dry. The wet season usually lasts from January to June, with the highest amount of rainfall and rainy days occurring between February and April. During this time, rains can be frequent, although not necessarily prolonged. The dry season typically sets in from August to November, when precipitation becomes a rarity and the number of sunny days is at its maximum.

Thus, the weather in Fortaleza is predictable in its seasonal manifestations. Travellers can expect constant heat, but the pronounced seasonality of rainfall should be taken into account when planning a trip, especially if dry and sunny weather is preferred.

The temperature pattern in Fortaleza is remarkably stable throughout the year, which is characteristic of an equatorial climate. The average annual temperature fluctuates within a very narrow range, ranging from approximately 26.6°C (in March) to 27.8°C (in November). This means travellers can count on consistently warm weather, regardless of the month chosen for the trip. The difference between the "coolest" and the hottest month in terms of average temperature is only about 1-1.5 degrees Celsius.

The hottest months in Fortaleza are generally November (average temperature 27.8°C) and December (average temperature 27.7°C). During this period, as well as in adjacent months such as August, September, and October, daily highs often reach 29.7°C - 29.9°C. The "coolest" months, if this term is applicable to Fortaleza's tropical climate, are considered to be March (average temperature 26.6°C) and July (average temperature 26.7°C). In these months, average minimum night-time temperatures may drop to 24.3°C - 24.9°C, which still ensures very warm nights.

Daily temperature fluctuations in Fortaleza are small. The difference between average daily highs and average nightly lows is usually between 3.4°C (in March) and 5.4°C (in August). This means that nights bring only a slight freshness, but not significant cooling. The greatest difference between day and night temperatures is observed in drier months, such as August and September. Overall, Fortaleza's climate can be described as constantly hot, with high humidity, especially during the rainy season (from January to June), but even in the dry season, the daytime heat is often softened by a pleasant ocean breeze.

In Fortaleza, as in many tropical regions, the pattern of rainfall is clearly divided into two main seasons: wet and dry. The wet season brings the majority of annual precipitation and falls in the first half of the year, while the second half of the year is characterised by significantly less rain, and at times a complete absence thereof, according to the provided data.

The rainy season in Fortaleza usually lasts from January to May, reaching its peak between February and April. Precipitation is most likely during these months. For example, in February and April, the highest amount of precipitation falls, according to the provided data, about 10 mm on average per month. At the same time, March stands out as the month with the maximum number of rainy days – precipitation can be observed almost daily, averaging up to 30 days per month, with a total volume of about 9 mm. January and May are also quite wet, with 22-23 rainy days, although the total amount of precipitation in these months is somewhat lower (3-5 mm). The nature of the rains during this period, judging by the ratio of rainfall amount to the number of rainy days, most often represents short or not very intense precipitation.

The dry season in Fortaleza sets in roughly from July and continues until November. This period is characterised by a minimal amount of rainfall and an abundance of sunny days. The driest months are August, September, and October, when the average rainfall tends towards zero (0 mm). In September, for instance, there is on average just one rainy day. July and November are transitional months to and from the dry season, with a small amount of precipitation (1 mm) and 9 and 5 rainy days respectively. December is also relatively dry, with 2 mm of rainfall and approximately 13 rainy days, heralding the imminent start of a new wet season.

When packing for Fortaleza, remember that a warm tropical climate awaits you all year round. The basis of your wardrobe should be light, breathable clothing made from natural fabrics such as cotton or linen. Given average temperatures around 27°C, shorts, T-shirts, sundresses, and light trousers will be the ideal choice. Don't forget swimwear to enjoy the city's famous beaches. Essential companions will be high SPF sunscreen, sunglasses, and a hat for protection against the bright sun. Comfortable footwear, such as sandals or light trainers, is also extremely important for walking.

If your trip falls within the period from January to June, be prepared for the rainy season. Although the temperature remains high, precipitation is a frequent occurrence at this time, especially from February to April, when the number of rainy days can reach 24-30 per month. We recommend taking a light waterproof raincoat or a compact umbrella. Clothing made from quick-drying materials may also prove useful. Despite the rains, which can be frequent but not always prolonged, heavy or overly warm clothing will not be needed.

From July to December, a drier season arrives in Fortaleza, with minimal rainfall, especially from August to October when there are practically no rainy days. During this time, the emphasis shifts to maximum sun protection and light clothing. Nevertheless, even in the dry season, for evening walks or in case of visiting air-conditioned places, a light wrap or thin cardigan may come in handy. Although the probability of rain is low, a small umbrella or a very light rain jacket won't take up much space and might help out during a sudden tropical shower, especially in transitional months such as July or December.
