Weather in September

Throughout September, the heat index is appraised at a very hot 100.4°F (38°C). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.Bear in mind that the heat index values are determined for shaded areas and light breezes. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Children commonly overlook the importance of rest and fluid replenishment. Thirst, being a delayed sign of dehydration, emphasizes the need to keep hydration up, especially during lengthy physical activities.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
