Weather in April
Temperature
April denotes a minimal variation in the average high-temperature to a still tropical 30.8°C (87.4°F) from March's 32.5°C (90.5°F). São Sebastião do Passé records an average low-temperature of 21.4°C (70.5°F) throughout the month of April.Heat index
For most parts of April, the heat index is computed to be a blisteringly hot 41°C (105.8°F). Emphasize additional safety, risk of heat cramps and heat exhaustion is high. Continuous activity might result in heatstroke.Always consider that heat index estimations are for light winds and places in the shade. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', arises from combining readings of air temperature and relative moisture content. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
