Temperature

April's climate shows a minor adjustment in average high-temperatures to a still moderately hot 29.7°C (85.5°F) from March's 29.5°C (85.1°F). Apatou observes an average nighttime temperature of 23.1°C (73.6°F) during April.

Heat index

April's heat index is evaluated at a torrid 38°C (100.4°F). Use additional protective measures, heat cramps and heat exhaustion are possible outcomes. Continuous activity might lead to heatstroke.
It is emphasized that the heat index's values are meant for shaded zones with mild winds. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young ones regularly neglect the requirement for rest and fluid replenishment. Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.

Note: The maximum daily UV index of 6 in April converts into the following recommendations:
Shun overexposure. Protection from sun ravages is indispensable. 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. A wide-brimmed hat provides unparalleled sun protection for sensitive areas like the eyes, ears, and neck.
