Temperature

April, with average temperatures reaching a high of 31.1°C (88°F) and a low of 26°C (78.8°F), is the warmest month.

Heat index

Throughout April, the heat index is evaluated at a blisteringly hot 40°C (104°F). Take more safety measures, heat exhaustion and heat cramps are potential outcomes. Persistent activity might lead to heatstroke.
It is important to note that the heat index values are for shaded areas and light wind scenarios. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
