Weather in September
Temperature
In September, the meteorological conditions change slightly, with the average high-temperature moving from a fiery hot 97°F (36.1°C) in August to a tropical 90.3°F (32.4°C). An average nighttime temperature of 74.8°F (23.8°C) is witnessed throughout September.Heat index
September's average heat index is evaluated at a scorching 105.8°F (41°C). Take additional safety steps, risk of heat exhaustion and heat cramps is notable. Prolonged activity may cause heatstroke.One should be cognizant that the heat index values are tailored for shaded spots and mild winds. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', gives a temperature feeling by integrating air temperature and humidity. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Children often overlook the necessity for resting and fluid replenishment. Thirst is a late sign of dehydration - thus, it is critical to stay hydrated, especially during extended periods of physical activities.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.

Persist with precautions and heed sun safety advice. Prevention of sunburn is compulsory. Limit your direct sun exposure, especially between 10 a.m. and 4 p.m., when UV radiation is strongest. Shade structures might not provide complete sun protection. Prioritize a wide-brim hat for comprehensive sun defense for your face, neck, eyes, and ears. Take into account! The reflection from snow can nearly double the Sun's UV radiation intensity.
