Weather in September
Temperature
The average high-temperature shows a slight dip in September, from August's 91.9°F (33.3°C) to a still tropical 86.2°F (30.1°C). Cooney temperatures generally rest at a low of 65.3°F (18.5°C) during the September nights.Heat index
September's heat index is estimated at a sweltering 96.8°F (36°C). Exercise enhanced safety steps, heat cramps and heat exhaustion are probable. Heatstroke could be a result of sustained activity.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.

Wearing a wide-brim hat can block approximately 50% of UV radiation, protecting the eyes.
