Weather in September
Temperature
September's arrival comes with a mild decrease in the average high-temperature, moving subtly from a torrid 95.9°F (35.5°C) in August to a tropical 87.6°F (30.9°C). An average minimum temperature of 70.2°F (21.2°C) is recorded during the month of September.Heat index
The heat index in September is estimated at a fiery hot 95°F (35°C). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.Heat index values are typically calculated for conditions of shade and a light breeze. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', evaluates the perceived heat by adding the effect of moisture in the air. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.
