Weather in April
Temperature
A minimal variation is noted in Ad Dirjaj's average high-temperature at the onset of April, reaching a still moderately hot 29.8°C (85.6°F) from March's 27.6°C (81.7°F). Ad Dirjaj's nocturnal average in April closely mirrors its daytime temperatures, settling at a still moderately hot 27.2°C (81°F).Heat index
During April, the heat index is evaluated at a very hot 36°C (96.8°F). Ensure additional precautions, heat exhaustion and heat cramps may be expected. Heatstroke could occur from sustained activity.It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. 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 'feels like' or 'felt air temperature', evaluates the perceived heat by adding the effect of moisture in the air. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
Humans rely on perspiration as a cooling mechanism, wherein the evaporating sweat counteracts excessive warmth. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
