Weather in August
Temperature
Transitioning from July to August, Millstadt observes an average high-temperature of a moderately hot 84.9°F (29.4°C), differing subtly from the previous month. Throughout August, the nighttime temperature averages to an enjoyable 66.6°F (19.2°C).Heat index
August's heat index is computed to be a torrid 95°F (35°C). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.Note that heat index values are valued for light wind and location in the shade. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical 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.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
