Weather in September
Temperature
September weather is marked by a drop in the average high-temperature, falling from a hot 93.7°F (34.3°C) in August to a moderately hot 84.6°F (29.2°C). During the month of September, Colony anticipates a mean low-temperature of 65.8°F (18.8°C).Heat index
The average heat index in September is calculated to be a hot 89.6°F (32°C). Exhaustion is likely with prolonged exposure and activity. Sustaining activity may result in heat cramps.Given the heat index, its values are aligned with shaded sites and gentle winds. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', joins air temperature with relative humidity to produce a temperature perception for humans. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
