Temperature

Stepping into April, Mayaia records an average high-temperature of a still tropical 30.8°C (87.4°F), almost consistent with March. In Mayaia, the average temperature during the nights of April drops to a warm 25.3°C (77.5°F).

Heat index

April's average heat index is calculated to be a sweltering 38°C (100.4°F). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.
Take into consideration that the heat index values are calculated for shade and light wind conditions. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', measures the perceived warmth when incorporating the humidity present in the air. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.

Humidity

In April, the average relative humidity in Mayaia is 74%.

UV index

Note: During April, 7 as the daily maximum UV index converts into the following advice:
Take precautions against overexposure. Fair-skinned people may get burned in less than 20 minutes. Stay in the shade and limit sun exposure from 10 a.m. to 4 p.m., when UV radiation is most potent. Keep in mind that shade structures like parasols or canopies do not offer full protection. Counter UV radiation's ill effects with clothing designed for sun safety and UV-resistant eyewear.
