Weather in September
Temperature
The transition to September results in a modest reduction in average high-temperature, moving from a hot 86°F (30°C) in August to a warm 80.6°F (27°C). An average low-temperature of 60.6°F (15.9°C) marks the nights throughout September.Heat index
September's heat index is estimated at 84.2°F (29°C). Persisting in activity during long-term exposure might induce weariness, with subsequent heat cramps.Consider that heat index readings are for situations in the shade and light wind. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', offers an insight into how hot it feels when we factor in moisture content. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
