August weather forecast
Spring Hill, TN

Following July's peak, August brings a slight reduction in temperatures, setting the stage for the approaching autumn. Although August temperatures take a minor dip from July, the month still sees a high rainfall of 1.85" (47mm). With the summer sun generously flooding the city, there are ample opportunities for residents to make the most of these outdoor-friendly conditions. August marks the conclusion of the peak summer months, and the beginning of a transition into the cooler autumn season. With the gradual change in weather, residents look forward to the upcoming autumnal hues that define Spring Hill's landscapes in the following months.

Temperature

The beginning of August records an average high-temperature of a still hot 86.5°F (30.3°C), almost echoing the conditions of the previous month. Nighttime temperature lowers to an average of 67.6°F (19.8°C) in August.

Heat index

In August, the average heat index is computed to be a torrid 98.6°F (37°C). Adopt extra preventive measures, the occurrence of heat cramps and heat exhaustion is likely. Heatstroke may follow extended activity.
Given the heat index, its values are aligned with shaded sites and gentle winds. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.

Note: The UV index of 6 during August leads to these advisories:
Implement preventive steps and embrace sun safety standards. Protection from skin and eye distress is compulsory. Stay in the shade and limit direct sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its strongest. Remember, however, that not all shade structures provide full sun protection. Experience reduced UV exposure by about half when donning a wide-brim hat.
