Porto Real do Colégio starts April with an average high-temperature of a still tropical 30.9°C (87.6°F), hinting at a minimal fluctuation from March. During April, the nighttime temperature averages to a moderately hot 23.6°C (74.5°F).

Heat index

During April, the heat index is evaluated at a scorching 40°C (104°F). More preventive actions are needed, risk of heat exhaustion and heat cramps is significant. Prolonged activity may trigger heatstroke.
Heat index's context suggests values are appropriate for shady areas and slight breezes. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'apparent temperature' or 'feels like', evaluates the perceived heat by adding the effect of moisture in the air. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.
