Heat index

September's mean heat index is estimated at a sweltering 38°C (100.4°F). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.
Always consider that heat index estimations are for light winds and places in the shade. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is the outcome of merging air's temperature and its humidity metrics. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

Uphold preventive measures and conform to sun safety guidelines. Defending against skin and eye harm is crucial. Try to minimize direct Sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Also note that objects like parasols or canopies might not provide complete sun protection. Wearing sunglasses with both UVA and UVB protection effectively reduces sun-induced eye damage.
