Weather in September
Temperature
The start of September comes with a small reduction in the average high-temperature, subtly receding from a sweltering 96.6°F (35.9°C) in August to a hot 89.1°F (31.7°C). In Geronimo, the average nighttime temperature during September is a pleasant 71.1°F (21.7°C).Heat index
For most parts of September, the heat index is calculated to be a sweltering 102.2°F (39°C). Use additional protective measures, heat cramps and heat exhaustion are possible outcomes. Continuous activity might lead to heatstroke.Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a single figure representing how weather conditions feel when combining temperature and humidity. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
