Temperature

The onset of April manifests an average high-temperature of a fiery hot 39.5°C (103.1°F), demonstrating a minor variation from the preceding month. Chumael notes a substantial temperature decline from the daytime peaks throughout April, with an average nighttime temperature of 20.8°C (69.4°F).

Heat index

In April, the heat index is computed to be a blazing hot 53°C (127.4°F). Beware: Heat exhaustion along with heat cramps are on the cards. Heatstroke could result from sustained physical activity.
When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Humidity

The average relative humidity in April is 50%.

It's wise to wear UVA and UVB-blocking sunglasses when the sun shines brightly.
