Weather in September
Temperature
The unfolding of September shows an average high-temperature of a moderately hot 85.5°F (29.7°C), indicating a slight variance from August's 90.1°F (32.3°C). Nighttime temperatures consistently average an agreeable 68.4°F (20.2°C) during September.Heat index
September's average heat index is evaluated at a sweltering 96.8°F (36°C). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'feels like', combines air temperature and relative humidity to represent a human perceived temperature equivalent. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. 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 of high significance for children. Children commonly overlook the importance of rest and fluid replenishment. Thirst, being a delayed sign of dehydration, emphasizes the need to keep hydration up, especially during lengthy physical activities.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.

Skirt overexposure. People with light complexions might get scorched in under 20 minutes. Try to minimize direct Sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Also note that objects like parasols or canopies might not provide complete sun protection. Sunglasses that ward off UVA and UVB rays play a pivotal role in reducing solar eye damage.
