Weather in April

The heat index value for April is appraised at a blistering 41°C (105.8°F). Undertake additional safety actions, risk of heat cramps and heat exhaustion is significant. Persistent activity may induce heatstroke.The metrics for the heat index are tailored for both shady environments and light winds. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', blends air temperature and moisture content to represent the felt temperature to humans. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical 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.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
