Weather in September
Temperature
With the beginning of September, the average high-temperature shows a small decrease, transitioning from a very hot 96.1°F (35.6°C) in August to a hot 87.8°F (31°C). University Park records an average temperature drop to a pleasant 70.5°F (21.4°C) in September.Heat index
The heat index in September is calculated to be a sweltering 95°F (35°C). Adopt extra safety steps, risk of heat exhaustion and heat cramps is notable. Sustained activity might cause heatstroke.The standards for the heat index are set for locations in shade and under light breezes. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'feels like' or 'felt air temperature', shows a temperature sensation when both heat and moisture conditions are combined. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

Eschew overexposure. Those with light skin may suffer burns in fewer than 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 providing both UVA and UVB protection are non-negotiable on sunlit days.
