Weather in September
Temperature
Pelican's progression into September involves a gentle drop in the average high-temperature, from a sweltering 95°F (35°C) in August to a hot 88.9°F (31.6°C). Pelican's average low-temperature in the month of September is recorded at a refreshing 67.6°F (19.8°C).Heat index
The average heat index in September is computed to be a scorching 104°F (40°C). Undertake additional safety actions, risk of heat cramps and heat exhaustion is significant. Persistent activity may induce heatstroke.Understanding the heat index involves considering values for shaded locales with light wind. 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 'apparent temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Guard oneself from overexposure. Defence against sun injury is vital. The Sun emits the most powerful UV radiation between 10 a.m. and 4 p.m. Try to avoid direct sunlight during this period. Using UVA and UVB-protective sunglasses and sun-protective clothing is effective against UV radiation. Heed this! Snow reflection can almost augment the UV radiation of the sun by double.
