Weather in September
Temperature
The onset of September brings a small shift in high-temperatures, falling from a tropical 93°F (33.9°C) in August to a still hot 87.6°F (30.9°C). Lunet documents a striking divergence from daytime highs, with an average nighttime temperature of 66°F (18.9°C) in September.Heat index
The heat index in September is computed to be a very hot 100.4°F (38°C). Take more preventive steps, risk of heat exhaustion and heat cramps is elevated. Long activity may culminate in heatstroke.The standards for the heat index are set for locations in shade and under light breezes. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is achieved by amalgamating air temperature with the relative humidity readings. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.

Undertake precautions and comply with sun safety standards. Protection from skin and eye injury is vital. Avoid direct Sun exposure and seek shade between 10 a.m. and 4 p.m., when UV radiation is at its peak, but keep in mind that not all shade structures provide complete protection.
