Heat index

The heat index for September is calculated to be a blazing hot 47°C (116.6°F). Be alert: Heat exhaustion along with heat cramps are probable. Heatstroke is a threat with sustained physical activity.
Understanding the heat index involves considering values for shaded locales with light wind. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is found by incorporating humidity levels into the air temperature measurement. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.

The Sun's UV radiation is most potent between the hours of 10 a.m. and 4 p.m. Try to avoid direct sunlight during this time. A wide-brim hat offers excellent sun protection for the eyes, ears, face, and neck. Sunglasses with UVA and UVB protection significantly reduce eye damage from sun exposure.
