Heat index

The heat index in September is calculated to be a very hot 98.6°F (37°C). Undertake additional safety actions, risk of heat cramps and heat exhaustion is significant. Persistent activity may induce heatstroke.
Heat index data is primarily for areas with shade and subjected to light winds. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', combines air temperature and relative humidity to represent a human perceived temperature equivalent. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are highly critical to babies and toddlers. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

Note: The maximum UV index, 7 during September, leads to the following recommendations:
Sidestep overexposure. Individuals with fair complexions risk burning in fewer than 20 minutes. Minimize exposure to direct sunlight and seek shade from 10 a.m. to 4 p.m., when UV radiation is most intense, but remember that shade structures may not offer complete protection. Sunglasses that ward off UVA and UVB rays play a pivotal role in reducing solar eye damage.
