Heat index

The heat index value for April is computed to be a blisteringly hot 43°C (109.4°F). Caution: Heat cramps along with heat exhaustion are expected. Sustained activity could lead to heatstroke.
Be informed that the heat index values are oriented around shady conditions and gentle breezes. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', melds the effects of warmth and moisture to generate a feeling of heat. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. 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. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.

Humidity

The average relative humidity in April is 77%.

Uphold preventive measures and conform to sun safety guidelines. Defending against skin and eye harm is crucial. Seek shade and limit direct Sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its peak, but be aware that not all shade structures provide complete sun protection. Counter UV radiation's ill effects with clothing designed for sun safety and UV-resistant eyewear.
