Weather in September

Continuous activity might lead to heatstroke.When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', blends air temperature and moisture content to represent the felt temperature to humans. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
