The dry season lasts from June to December, when rainfall is scarce and temperatures are slightly lower. The transition between the seasons is gradual, with a slight increase in rainfall in September and October. The city receives an average of 1,400 millimeters (55 inches) of precipitation per year, mostly concentrated during the wet season.
Cloud Patterns and Types
Fortaleza’s skies are characterized by a variety of cloud patterns, ranging from towering cumulonimbus clouds that produce thunderstorms to wispy cirrus clouds that add a delicate touch to the sky. During the rainy season (January to June), cumulus and cumulonimbus clouds dominate, bringing frequent showers and occasional downpours. The dry season (July to December) features more stable atmospheric conditions, leading to a greater prevalence of stratocumulus and altostratus clouds. These clouds typically appear as uniform layers or sheets, covering the sky partially or completely.
Cloud Formation and Impact
The formation of clouds in Fortaleza is influenced by several factors, including rising air currents, moisture content, and temperature. The city’s proximity to the Atlantic Ocean provides a constant source of moisture, which evaporates and rises into the atmosphere. As the air rises, it cools, causing the water vapor to condense into water droplets or ice crystals, forming clouds. These clouds can have a significant impact on the local climate, providing shade from the sun, contributing to precipitation, and even affecting air quality. For example, during the rainy season, heavy cloud cover and rainfall help to lower temperatures and reduce humidity, providing some relief from the tropical heat.
Annual Precipitation Patterns
Fortaleza experiences a tropical wet-dry climate with two distinct seasons: the wet season from January to May and the dry season from June to December. During the wet season, Fortaleza receives abundant rainfall, averaging over 200 millimeters per month. The peak rainfall occurs in March and April, when monthly precipitation can exceed 300 millimeters. In contrast, the dry season is characterized by significantly reduced rainfall, with monthly precipitation typically below 100 millimeters. The lowest rainfall occurs in September and October, when Fortaleza often experiences drought conditions.
Variability and Extremes
The annual precipitation in Fortaleza exhibits considerable variability from year to year. During wet years, the city can receive over 1,500 millimeters of rainfall, while in dry years, it may receive less than 500 millimeters. This variability is influenced by factors such as El Niño-Southern Oscillation (ENSO) events, which can cause changes in ocean temperatures and atmospheric circulation patterns that affect precipitation. Additionally, Fortaleza is vulnerable to extreme rainfall events, which can lead to flooding and infrastructure damage. In recent years, the city has experienced several such events, including the devastating floods of 2018 that caused widespread damage and displacement.

Humidity Levels in Fortaleza
Fortaleza experiences consistently high humidity levels year-round due to its tropical climate and proximity to the Atlantic Ocean. The average relative humidity throughout the year ranges from 75% to 85%, creating a muggy and uncomfortable atmosphere. The highest humidity levels typically occur during the warmer months from December to April, where they can reach up to 90% or higher. During this time, the air feels thick and oppressive, making physical activities and outdoor work challenging.
Factors Influencing Humidity
Several factors contribute to the high humidity in Fortaleza. The city’s location near the equator results in high temperatures throughout the year, which increases the rate of evaporation from the ocean. Additionally, the prevailing northeasterly trade winds carry moisture from the Atlantic Ocean towards the coast, further contributing to the high humidity levels. The topography of Fortaleza also plays a role, as the city is surrounded by hills that can trap moisture from the ocean.
Seasonal Variations
Fortaleza, located in the northeastern part of Brazil, experiences a distinct pattern of seasonal wind variations. During the summer months from January to March, the city is predominantly influenced by southeasterly trade winds. These winds originate from the South Atlantic Ocean and provide refreshing breezes, keeping the temperatures moderate despite the high humidity. Conversely, from June to September, Fortaleza falls under the influence of stronger northeasterly trade winds known as the “Sula.” These winds bring increased humidity and occasional heavy rainfall, contributing to the city’s distinctive wet season.
Role of the Trade Winds
The trade winds play a crucial role in shaping the climate of Fortaleza. The southeasterly trade winds, prevalent during the summer, help regulate temperatures and mitigate the oppressive heat. They also carry moisture from the ocean, which contributes to the city’s humid conditions. During the wet season, the northeasterly trade winds bring an abundance of rainfall, replenishing water sources and supporting the region’s vegetation. The strength of these winds can vary significantly, sometimes leading to strong gusts or occasional storms. Understanding these seasonal variations is essential for planning outdoor activities, such as beach visits or water sports, as the winds can influence wave conditions and visibility.
Best Time for Rainy Weather and Fewer Crowds
If you prefer to avoid crowds and enjoy rainy weather, the best time to visit Fortaleza is during the rainy season, which typically runs from late March to June. During this time, the city receives ample rainfall, making it a great destination for those who enjoy lush greenery and tropical downpours. While the rain can sometimes lead to occasional showers or thunderstorms, it also brings a welcome respite from the hot and humid weather. Additionally, the off-season offers lower prices on accommodations and tourist attractions, making it an ideal time for budget travelers.
Best Time for Dry Weather and Beach Activities
For those seeking dry weather and optimal conditions for beach activities, the best time to visit Fortaleza is during the dry season, which lasts from July to December. This period offers clear skies, low humidity, and minimal rainfall, making it perfect for sunbathing, swimming, surfing, and other outdoor adventures. The warm ocean temperatures and calm waters during this time create an idyllic setting for water sports enthusiasts. Fortaleza’s vibrant beaches come alive during the dry season, with locals and tourists enjoying the lively atmosphere and picturesque surroundings. However, it is important to note that this peak season can result in higher accommodation rates and larger crowds.
