Weather in September
Temperature
September commences with an average high-temperature of a still hot 87.3°F (30.7°C), showing little deviation from August's 90.9°F (32.7°C). Bruns experiences a nighttime temperature average of 70.5°F (21.4°C) during September.Heat index
For September, the heat index is evaluated at a blistering 104°F (40°C). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.Records show heat index calculations are tailored for shaded regions and mild winds. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is found by incorporating humidity levels into the air temperature measurement. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.

Inhibit overexposure. Warding off sun damage is of utmost importance. Between 10 a.m. and 4 p.m., the Sun's UV radiation is at its peak. Limit your exposure to direct sunlight during these hours. Consider a wide-brim hat essential for effective sun defense covering your face, neck, and eyes.
