Weather in September
Temperature
September signifies a minor drop in average high-temperature, transitioning from a tropical 92.5°F (33.6°C) in August to a still hot 86.4°F (30.2°C). An average nighttime temperature of 64.9°F (18.3°C) is witnessed throughout September.Heat index
Throughout September, the heat index is computed to be a very hot 96.8°F (36°C). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.Bear in mind that the heat index values are determined for shaded areas and light breezes. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', blends air temperature and moisture content to represent the felt temperature to humans. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

In September, the average daily maximum UV index is 6. A UV Index reading of 6 to 7 represents a high health hazard from unsafe exposure to UV radiation for the ordinary person.Note: During September, 6 as the daily maximum UV index converts into the following advice:
Enforce precautions and stick to sun safety measures. Preservation from skin and eye damage is essential. Stay in the shade and limit direct sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its strongest. Remember, however, that not all shade structures provide full sun protection. To cut down UV radiation exposure by about half, sport a wide-brim hat. Mind this! Nearly twice the UV radiation from the Sun can be reflected by the snow.
