Weather in September
Temperature
The average high-temperature during September registers at a moderately hot 82°F (27.8°C), closely corresponding to the preceding month. An average nighttime temperature of 63°F (17.2°C) is noted during the month of September.Heat index
September's heat index is estimated at a hot 87.8°F (31°C). Persistent activity under exposure might lead to a feeling of weariness, with subsequent heat cramps.Be advised, the heat index considers values for conditions in shade and with a light breeze. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. 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. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
