Weather in September
Temperature
September implies a soft temperature shift, with average high-temperatures reducing from August's 94.6°F (34.8°C) to a still tropical 88.7°F (31.5°C). Throughout September, Prairie View encounters an average temperature drop to an agreeable 70.7°F (21.5°C).Heat index
In September, the heat index is appraised at a blistering 105.8°F (41°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.Heat index's context suggests values are appropriate for shady areas and slight breezes. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', offers an insight into how hot it feels when we factor in moisture content. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
