Heat index

April's mean heat index is estimated at an extremely hot 44°C (111.2°F). Take heed: Heat exhaustion and heat cramps are anticipated. Heatstroke is a potential outcome of continuous activity.
Know that the heat index computations account for shaded terrains and slight winds. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'feels like', reflects the blend of air temperature and relative humidity to give a temperature impression. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

Humidity

In April, the average relative humidity is 72%.

Note: The maximum UV index, 8 during April, leads to the following recommendations:
Take special precautions, as unprotected eyes and skin can be burned and damaged quickly. 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. Equip yourself with UVA and UVB-filtering sunglasses on clear, sunny days.
