Weather in September
Temperature
September's presence records an average high-temperature of a still hot 87.8°F (31°C), closely mirroring August's climate. Walters's September nights cool down to an average low-temperature of 67.6°F (19.8°C).Heat index
For most parts of September, the heat index is calculated to be a very hot 102.2°F (39°C). Take additional safety steps, risk of heat exhaustion and heat cramps is notable. Prolonged activity may cause heatstroke.It is important to note that the heat index values are for shaded areas and light wind scenarios. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is the outcome of merging air's temperature and its humidity metrics. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
