Weather in April
Temperature

For April, the heat index is calculated to be a scorching 41°C (105.8°F). Take more preventive steps, risk of heat exhaustion and heat cramps is elevated. Long activity may culminate in heatstroke.Research indicates the heat index considers values in shaded locales and with light winds. The direct sunshine could escalate the heat index values 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 impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly important for children. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
