Weather in April
Temperature
Fortim, Brazil, records an average high-temperature of a still tropical 30.7°C (87.3°F) in April, maintaining a close correlation with March's 30.8°C (87.4°F). In the month of April, Fortim records a consistent average low-temperature of 25.3°C (77.5°F).Heat index
April's heat index is computed to be a very hot 39°C (102.2°F). Ensure heightened precautions, risk of heat cramps and heat exhaustion is significant. Sustained activity could provoke heatstroke.Understand that the heat index values take into account shaded locations and mild winds. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', gives an indication of how one might feel in terms of heat after considering humidity. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. When there is abundant moisture in the air, the body's cooling through the evaporation process becomes less effective, leading to the sensation of overheating. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.

A UV Index reading of 6 to 7 represents a high threat to health from exposure to the Sun's UV radiation for the average person.Note: The UV index of 7 during April translates into the following guidance:
Avert overexposure. Light-skinned people might experience burning in less than 20 minutes. Between 10 a.m. and 4 p.m., the Sun's UV radiation is at its peak. Limit your exposure to direct sunlight during these hours. Experience reduced UV exposure by about half when donning a wide-brim hat.
