Weather in September
Temperature
A subtle shift in Ames's weather is observed as August turns into September, with the average high temperature reducing from 93.4°F (34.1°C) to a still tropical 87.6°F (30.9°C). Ames registers a significant drop in temperature in September, with average nighttime lows of 66°F (18.9°C).Heat index
The heat index value for September is calculated to be a torrid 100.4°F (38°C). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.Heat index specifics point out values are for conditions of shade and a slight breeze. 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', unifies temperature and humidity readings to offer a comprehensive feel of warmth. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are largely significant for babies and toddlers. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
