Weather in April
Temperature
April proves to be the warmest month, recording an average peak temperature of 32.9°C (91.2°F) and a minimum temperature of 22°C (71.6°F).Heat index
The heat index in April is calculated to be a blazing hot 46°C (114.8°F). Stay watchful: Heat exhaustion along with heat cramps are likely. Ongoing effort may cause heatstroke.Heat index guidelines indicate values are for light wind scenarios and shaded regions. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', shows a temperature sensation when both heat and moisture conditions are combined. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
One of the main methods the human body employs to cool down is by perspiring, as this process allows sweat to evaporate and remove excess heat. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
