Weather in September
Temperature
A mild shift in the average high-temperature occurs in September, reducing from a fiery hot 97°F (36.1°C) in August to a hot 89.4°F (31.9°C). During September, Waelder's temperature falls to a steady low-temperature average of 71.6°F (22°C).Heat index
During September, the heat index is appraised at an extremely hot 104°F (40°C). Take special precautions - heat exhaustion and heat cramps are expected. Heatstroke may occur with lengthy activity.It is essential to grasp that the heat index's numbers are for shade and light wind settings. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', evaluates the perceived heat by adding the effect of moisture in the air. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
