Weather in September
Temperature
The onset of September brings an average high-temperature of a warm 84.9°F (29.4°C), nearly matching the August temperature. An average nighttime temperature of 69.1°F (20.6°C) is noted during the month of September.Heat index
The heat index value during September is estimated at a sweltering 95°F (35°C). Incorporate additional safety actions, heat cramps and heat exhaustion are possible. Long-term activity may induce heatstroke.Take note of the fact that heat index values are based on shaded circumstances with light airflows. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', joins air temperature with relative humidity to produce a temperature perception for humans. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Kids often lack the knowledge about the necessity to take breaks and consume liquids. Thirst, as a late symptom of dehydration, necessitates the maintenance of hydration, particularly during enduring physical activities.
One of the main methods the human body employs to cool down is by perspiring, as this process allows sweat to evaporate and remove excess heat. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
