Weather in September
Temperature
The transition from August to September brings an average high-temperature of a moderately hot 84.2°F (29°C), barely different from August's 89.1°F (31.7°C). Govan records an average low-temperature of 67.6°F (19.8°C) throughout the month of September.Heat index
September's heat index is computed to be a hot 93.2°F (34°C). Undertake additional precautions, heat cramps and heat exhaustion could happen. Heatstroke could occur from sustained activity.Heat index data is primarily for areas with shade and subjected to light winds. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', marries air temperature and humidity to produce a value illustrating perceived warmth. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to 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.
