April in Brazil is considered the tail end of the wet season in many regions, transitioning into the drier months of May through September. The weather is characterized by warm to hot temperatures, but the occurrence of rain begins to decrease as the month progresses. Brazil’s vast size and diverse topography mean that weather conditions vary greatly across the country, from the tropical Amazon rainforest to the temperate southern regions.

Precipitation Levels
April in Brazil marks a transitional period where rainfall begins to decrease in most regions, particularly in the southern and southeastern parts of the country. However, rain is still a prominent feature, especially in the northern and central areas.
- Northern Brazil: The Amazon region remains one of the wettest parts of Brazil in April. Rainfall is common, and monthly precipitation levels range between 150 mm and 200 mm. The Amazon rainforest still experiences intense, frequent rain showers during this time, contributing to high humidity.
- Central Brazil: Central regions such as Brasília experience moderate rainfall, with monthly totals ranging from 80 mm to 120 mm. April typically marks the end of the rainy season, and although there may still be showers, they are less frequent than in the preceding months.
- Southeast Brazil: Rio de Janeiro and São Paulo receive moderate rainfall in April, averaging between 80 mm and 100 mm of rain. The rains are often lighter and less intense compared to the wet season, and the skies can be partly cloudy with occasional downpours, especially during the afternoon.
- Southern Brazil: The southern region of Brazil, including cities like Porto Alegre and Curitiba, experiences more moderate rainfall than the north. Precipitation levels in southern Brazil are usually between 60 mm and 90 mm, and the rain typically becomes less frequent as the month progresses.
- Snow: Snowfall is extremely rare in Brazil in April, with the exception of the higher altitudes of the southern region, such as the Serra Gaúcha region in the state of Rio Grande do Sul. However, any snowfall is typically light and sporadic.
Wind Patterns
April in Brazil sees moderate to light wind patterns across the country, with the strength and direction of winds varying based on location. Coastal regions experience more consistent winds, while inland areas tend to have calmer weather.
- Coastal Regions: Coastal cities like Rio de Janeiro, Recife, and Salvador experience moderate winds, with average speeds ranging from 10 km/h to 20 km/h. These winds help maintain a comfortable temperature, particularly during the warmer daytime hours. In Rio de Janeiro, winds can increase due to the city’s proximity to the sea, creating a refreshing breeze, especially in the late afternoon.
- Inland Regions: In cities like Brasília, Goiânia, and Cuiabá, winds are generally lighter, with speeds ranging between 5 km/h and 15 km/h. These winds can be sporadic and tend to pick up during thunderstorms or weather systems passing through the region.
- Northern Brazil: In the Amazon region, winds are typically light to moderate, with speeds ranging from 10 km/h to 20 km/h. Winds are more common along the coast of the Amazon River and other bodies of water, providing some relief from the humidity.
- Southern Brazil: In the southern part of the country, wind speeds are moderate to strong, particularly in coastal areas like Porto Alegre. Wind speeds can range from 15 km/h to 30 km/h, and these winds help bring cooler air, particularly in the late afternoon and evening.
Atmospheric Pressure
April in Brazil experiences relatively stable atmospheric pressure, though fluctuations in pressure can occur due to passing weather systems, particularly in the northern and central regions. The weather is generally affected by high and low-pressure systems that bring rain and storms.
- High Pressure: During most of April, high-pressure systems dominate, particularly in southern Brazil. These systems lead to stable, drier weather with clearer skies and less rainfall. Cities like São Paulo and Porto Alegre often experience sunny weather as the month progresses.
- Low Pressure: In the Amazon and central Brazil, low-pressure systems may still bring rainfall and thunderstorms, especially in the first half of April. These systems create periods of cloudy weather and can increase humidity levels temporarily.
Things to Consider for Travelers
Traveling to Brazil in April presents a unique opportunity to experience the country during a time of transition between the wet and dry seasons. However, travelers should be aware of the varying weather conditions depending on the region.
1. Pack for Warm and Humid Weather
Brazil is warm year-round, and even in April, the temperatures can be high, especially in the northern and central parts of the country. It’s important to pack lightweight, breathable clothing for daytime activities, but also a jacket or sweater for cooler evenings in southern regions. In coastal regions, it can be humid, so light fabrics like cotton and linen are ideal.
2. Rain Gear for Unpredictable Showers
While April marks the end of the rainy season in many parts of Brazil, rain is still common, especially in northern and central regions. Be sure to bring an umbrella or a light waterproof jacket for occasional downpours. Waterproof footwear may also be a good idea, particularly for outdoor activities.
3. Sun Protection
Brazil’s tropical climate means strong sunlight, so sunscreen, sunglasses, and a wide-brimmed hat are essential for protection from the sun’s UV rays. Apply sunscreen regularly, especially when visiting coastal areas or engaging in outdoor activities like hiking or sightseeing.
4. Humidity Considerations
In coastal regions like Rio de Janeiro and Salvador, the humidity can make the weather feel much warmer than the actual temperature. Travelers should stay hydrated and avoid strenuous activities during the hottest parts of the day. Cooling off in the ocean or enjoying shaded areas can help mitigate the effects of high humidity.
5. Travel Flexibility Due to Rain
Since rain is still possible in April, especially in the first half of the month, it’s a good idea to keep your travel plans flexible. Consider having indoor activities or backup plans in case rain interrupts your outdoor plans, particularly if you’re planning to explore national parks or go on a safari.
6. Tourism Considerations
April is part of the shoulder season in Brazil, meaning that tourist spots are less crowded than in the high season (December through February). This makes it an ideal time for those seeking a more relaxed travel experience. However, some attractions or services may be limited due to the lower number of visitors.
7. Health Precautions
Due to the tropical climate, mosquitoes are prevalent in many regions of Brazil, particularly in the north and the Amazon. Be sure to carry insect repellent and take necessary precautions to avoid mosquito bites, especially if you are visiting areas where malaria is present. Also, ensure that your vaccinations are up to date before traveling to Brazil.
