Weather in September
Temperature
The commencement of September indicates a gentle shift in the average high-temperature, receding from August's fiery hot 95.4°F (35.2°C) to a hot 88.2°F (31.2°C). During September, the temperature in Sheridan is averaged to a low of 71.4°F (21.9°C) at night.Heat index
The heat index in September is evaluated at a fiery hot 102.2°F (39°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.Realize that the values for the heat index are set for shaded places and light winds. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', measures the perceived warmth when incorporating the humidity present in the air. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
