Weather in September
Temperature
With the onset of September, the average high-temperature stands at a moderately hot 85.1°F (29.5°C), closely aligned with August's 89.4°F (31.9°C). Throughout the nights in September, an average low-temperature of 70.9°F (21.6°C) is noted.Heat index
Throughout September, the heat index is calculated to be a very hot 95°F (35°C). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.Take note of the fact that heat index values are based on shaded circumstances with light airflows. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', evaluates the perceived heat by adding the effect of moisture in the air. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. When the body's heat gain surpasses its removal capacity, body temperature starts to climb, leading to potential heat-related ailments.
