Weather in September
Temperature
A subtle shift in Stampede's weather is observed as August turns into September, with the average high temperature reducing from a torrid 96.4°F (35.8°C) to a hot 88.7°F (31.5°C). Throughout September, Stampede witnesses a consistent average low-temperature of 70.7°F (21.5°C).Heat index
The heat index value during September is computed to be a torrid 98.6°F (37°C). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

Escape overexposure. People with light skin may incur burns in fewer than 20 minutes. Between 10 a.m. and 4 p.m., UV radiation is strongest. Make an effort to avoid direct sunlight during this time, remembering that shade structures may not provide full sun protection. For effective sun eye protection, rely on sunglasses certified for UVA and UVB resistance.
