Weather in September
Temperature
The commencement of September brings an average high-temperature of a moderately hot 85.3°F (29.6°C), marking an inconsequential divergence from August. An average low-temperature of 67.8°F (19.9°C) is anticipated throughout the nights during September.Heat index
In September, the heat index is evaluated at a sweltering 95°F (35°C). Use additional protective measures, heat cramps and heat exhaustion are possible outcomes. Continuous activity might lead to heatstroke.Take note of the fact that heat index values are based on shaded circumstances with light airflows. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
