Heat index

The heat index value during October is evaluated at a blisteringly hot 43°C (109.4°F). Keep on guard: Heat exhaustion and heat cramps are probable. Heatstroke is a possible danger with ongoing physical activity.
Note that heat index values are valued for light wind and location in the shade. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is the result of factoring in humidity to the air temperature, indicating perceived warmth. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for 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.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.

Steer clear of overexposure. Fair-skinned individuals can be scorched in less than 20 minutes. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is at its strongest, and remember that parasols or canopies do not offer full protection. Wearing a wide-brim hat can block approximately 50% of UV radiation, protecting the eyes.
