Weather in September
Temperature
The beginning of September subtly marks a decrease in the average high-temperature, transitioning from a tropical 94.8°F (34.9°C) in August to a still hot 87.1°F (30.6°C). Melissa's average low-temperature in the month of September is recorded at a pleasant 68.9°F (20.5°C).Heat index
The heat index value for September is evaluated at a torrid 95°F (35°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.Remember that heat index calculations are made for conditions in the shade with light wind. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a single figure representing how weather conditions feel when combining temperature and humidity. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.
