Weather in September
Temperature
September's advent denotes a minor fluctuation in the average high-temperature to a still hot 86.2°F (30.1°C) from August's 91°F (32.8°C). West's average low-temperature in the month of September is recorded at a refreshing 66.7°F (19.3°C).Heat index
September's mean heat index is estimated at a fiery hot 96.8°F (36°C). Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.The standards for the heat index are set for locations in shade and under light breezes. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', reflects the blend of air temperature and relative humidity to give a temperature impression. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are of high significance for 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.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
