Weather in September
Temperature
The onset of September results in a small decrease in the average high-temperature, moderately receding from a hot 88°F (31.1°C) in August to a moderately hot 82.6°F (28.1°C). Throughout September, the temperature falls to an average low of 61.3°F (16.3°C).Heat index
September's mean heat index is calculated to be a hot 89.6°F (32°C). If one continues to be active during enduring exposure, it could result in fatigue and heat cramps.It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is the outcome of merging air's temperature and its humidity metrics. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
