Welcoming September, Speed notes an average high-temperature of a moderately hot 81.3°F (27.4°C), nearly consistent with August's 86.4°F (30.2°C). Throughout September, the average low-temperature dips to a comfortable 64.2°F (17.9°C).Heat index
September's heat index is estimated at a hot 86°F (30°C). Enduring exposure and continuous activity might cause a feeling of tiredness and induce heat cramps.When assessing, remember that heat index measurements are for light winds and shaded spots. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', determines the feeling of heat when you account for the relative humidity. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
