Weather in September
Temperature
Transitioning into September, Devalls records an average high-temperature of a still hot 88°F (31.1°C), almost identical to August's 91.9°F (33.3°C). In September, Devalls's temperature tends to fall to an average low of 70°F (21.1°C) during the night.Heat index
Throughout September, the heat index is calculated to be a scorching 105.8°F (41°C). Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.Evaluating the heat index requires understanding its values in the shade and with gentle winds. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', combines both the air temperature and the humidity level to give a perceived human temperature. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
