Temperature

The commencement of April brings an average high-temperature of a warm 29.6°C (85.3°F), marking an inconsequential divergence from March. During April, Maceió witnesses a consistent average low-temperature of 22.5°C (72.5°F).

Heat index

The heat index value during April is evaluated at a torrid 37°C (98.6°F). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.
Heat index guidelines indicate values are for light wind scenarios and shaded regions. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.

Take every vital safeguard, as unprotected skin and eyes may suffer burns rapidly. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. In the presence of strong sunlight, it's crucial to wear sunglasses that ward off UVA and UVB rays. Even when it's cloudy, ensure the generous application and frequent reapplication of a sunscreen with at least 30 SPF, particularly post swim or outdoor activity. Beware! Reflecting off water and sand, UV rays are much stronger.
