Weather in August
Temperature
The shift into August records an average high-temperature of a still tropical 90.1°F (32.3°C), subtly varied from July's 90.3°F (32.4°C). In August, Union experiences an average nighttime temperature of 74.8°F (23.8°C).Heat index
The heat index for August is calculated to be a blazing hot 113°F (45°C). Attention: Heat exhaustion and heat cramps are anticipated. Prolonged effort can result in heatstroke.It is emphasized that the heat index's values are meant for shaded zones with mild winds. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'real feel' or 'felt air temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
