Heat index

September's heat index is calculated to be a sweltering 95°F (35°C). Take more safety measures, heat exhaustion and heat cramps are potential outcomes. Persistent activity might lead to heatstroke.
Heat index guidelines indicate values are for light wind scenarios and shaded regions. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'feels like' or 'apparent temperature', melds the effects of warmth and moisture to generate a feeling of heat. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

Stay clear of intense sun exposure. Solar protection is of utmost significance. Attempt to stay under shade and limit exposure to the Sun between 10 a.m. and 4 p.m., when UV radiation is at its peak. Remember, devices such as parasols or canopies might not provide complete sun protection. Stay sun-safe with clothing that is both closely woven and worn loosely. Notice! Sand and water reflections contribute to a stronger UV exposure.
