August ushers in the tail end of summer in Dexter with persistent hot conditions and extended daylight hours.

Despite this slight dip, August is hard to distinguish from the scorching July heat. The warm conditions persist through August with occasional showers. Although the hot spell continues, it becomes clear that summer in Dexter is on the cusp of winding down.

With August's arrival, Dexter's weather records an average high-temperature of a still hot 86.4°F (30.2°C), marking little difference from July's 88.2°F (31.2°C). Dexter, during the nights of August, experiences an average temperature drop to an enjoyable 67.8°F (19.9°C).

Heat index

For August, the heat index is appraised at a fiery hot 98.6°F (37°C). Undertake additional precautions, heat cramps and heat exhaustion could happen. Heatstroke could occur from sustained activity.
Given the heat index, its values are aligned with shaded sites and gentle winds. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is achieved by amalgamating air temperature with the relative humidity readings. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
