Weather in April
Temperature
With its high average temperature of 34.9°C (94.8°F) and a low of 23.4°C (74.1°F), April is regarded as the warmest month.Heat index
The average heat index in April is evaluated at a burning hot 48°C (118.4°F). Heed: Expect heat cramps and heat exhaustion. Continued action may cause heatstroke.Heat index values are typically calculated for conditions of shade and a light breeze. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', gives a temperature feeling by integrating air temperature and humidity. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
