Weather in September
Temperature
Austwell's shift into September is marked by a subtle change to a still tropical 86°F (30°C) from August's 89.6°F (32°C) in temperature. Austwell's nighttime average temperature in September subtly descends to a moderately hot 77.4°F (25.2°C) from the daily highs.Heat index
For September, the heat index is estimated at a sweltering 96.8°F (36°C). Ensure extra safety measures, heat exhaustion and heat cramps are likely. Continuous activity might result in heatstroke.It is emphasized that the heat index's values are meant for shaded zones with mild winds. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', integrates the air's temperature and its humidity to showcase the felt temperature by people. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 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.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.

Adopt measures and apply sun safety strategies. Shielding from skin and eye damage is necessary. The hours from 10 a.m. to 4 p.m. have the most intense UV radiation. As much as possible, limit direct sun exposure during this period. A hat with a generous brim can prevent nearly 50% of UV rays from reaching your eyes.
