Weather in September
Temperature
September's onset brings a negligible change in high-temperatures, falling from a sweltering 96.4°F (35.8°C) in August to a hot 87.4°F (30.8°C). During September, Hawley experiences a consistent low-temperature average of 68.9°F (20.5°C).Heat index
During September, the heat index is appraised at a hot 93.2°F (34°C). Undertake enhanced precautions, heat exhaustion and heat cramps are possible risks. Continuous activity could trigger heatstroke.Understanding the heat index involves considering values for shaded locales with light wind. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is found by incorporating humidity levels into the air temperature measurement. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.

Prevent overexposure. Protection from the sun's harmful effects is needed. Avoid exposure to the Sun and try to stay in the shade between 10 a.m. and 4 p.m., when UV radiation is most potent, but be aware that parasols or canopies may not offer full protection. On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes.
