Weather in September
Temperature
The onset of September brings a small shift in high-temperatures, falling from a sweltering 96.3°F (35.7°C) in August to a hot 88.5°F (31.4°C). In September, Ocaw records an average nighttime temperature of 70.5°F (21.4°C).Heat index
The average heat index in September is computed to be a torrid 98.6°F (37°C). Adopt heightened preventive measures, heat exhaustion and heat cramps are probable. Persistent activity could lead to heatstroke.Consider that heat index readings are for situations in the shade and light wind. 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 'feels like' or 'apparent temperature', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
