Weather in April
Temperature
The height of temperatures is seen during March and April, averaging a high-temperature of 30.3°C (86.5°F).Heat index
The heat index value for April is calculated to be a sweltering 38°C (100.4°F). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.Note that heat index values are valued for light wind and location in the shade. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
Humans rely on perspiration as a cooling mechanism, wherein the evaporating sweat counteracts excessive warmth. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.
