Weather in September
Temperature
As September unfolds, the average high-temperature reaches a warm 85.5°F (29.7°C), hinting at a slight fluctuation from the previous month. Throughout September, the average low-temperature dips to an enjoyable 66°F (18.9°C).Heat index
The heat index value for September is estimated at a torrid 95°F (35°C). Ensure heightened precautions, risk of heat cramps and heat exhaustion is significant. Sustained activity could provoke heatstroke.From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. Direct sunshine exposure could raise heat index values by as much as 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. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. 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.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
