Heat index

The heat index in November is evaluated at a torrid 38°C (100.4°F). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.
It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is the outcome of merging air's temperature and its humidity metrics. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.

Avoid excessive sunlight. Those with lighter skin may experience burning in less than 20 minutes. 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. Wearing sunglasses with both UVA and UVB protection effectively reduces sun-induced eye damage.
