The shift from March to April is characterized by an average high-temperature of a moderately hot 29.3°C (84.7°F), not significantly different from the 30.8°C (87.4°F) of March. During the month of April, Ponta do Mutá experiences a steady low-temperature average of 19.3°C (66.7°F).

Heat index

The heat index in April is estimated at a very hot 37°C (98.6°F). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.
Understand that the heat index values take into account shaded locations and mild winds. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly important for children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.

Humidity

In April, the average relative humidity is 85%.

Note: The daily high UV index of 6 during April translates into the following recommendations:
Deter overexposure. Protecting against the sun's effects is essential. Seek shade and limit direct Sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its peak, but be aware that not all shade structures provide complete sun protection. It's wise to wear UVA and UVB-blocking sunglasses when the sun shines brightly. Heads up! UV intensity is amplified by reflections from water and sand.
