Weather in September

For most parts of September, the heat index is evaluated at a fiery hot 98.6°F (37°C). Implement more preventive measures, heat cramps and heat exhaustion are probable. Heatstroke might result from extended activity.It is crucial to understand that heat index figures are for shade and gentle wind conditions. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', takes into account both air temperature and humidity to illustrate what people actually feel. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
