Heat index

During October, the heat index is evaluated at a scorching 42°C (107.6°F). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.
It is crucial to understand that heat index figures are for shade and gentle wind conditions. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', unifies temperature and humidity readings to offer a comprehensive feel of warmth. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. 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.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.

Avoid direct Sun exposure and seek shade between 10 a.m. and 4 p.m., when UV radiation is at its peak, but keep in mind that not all shade structures provide complete protection. Fend off the sun's harsh rays with appropriate clothing, a wide-brim hat, and UV-protective sunglasses. Broad-spectrum sunscreen with an SPF of 30 or more should be applied liberally every two hours and directly after outdoor activities or swimming.
