Weather in September
Temperature
September's weather displays an average high-temperature of a moderately hot 84.7°F (29.3°C), slightly varied from August's 88.9°F (31.6°C). Oakcrest experiences an average low-temperature of 68.2°F (20.1°C) in month of September.Heat index
For most parts of September, the heat index is estimated at a sweltering 95°F (35°C). Undertake additional precautions, heat cramps and heat exhaustion could happen. Heatstroke could occur from sustained activity.When referencing the heat index, its values are suitable for shady environments and light 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 'felt air temperature' or 'apparent temperature', quantifies the warmth felt when relative humidity is considered. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Young ones regularly neglect the requirement for rest and fluid replenishment. Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.
