Temperature

Sycamore Hills signifies an average high-temperature of a moderately hot 85.5°F (29.7°C) in August, closely mirroring the 86.9°F (30.5°C) of July. During the month of August, an average temperature of 67.1°F (19.5°C) is noted during the nights.

Heat index

The heat index in August is evaluated at a sweltering 95°F (35°C). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.
It is emphasized that the heat index's values are meant for shaded zones with mild winds. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is found by incorporating humidity levels into the air temperature measurement. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. As body temperatures escalate without effective heat release, one might face dehydration threats.
