Weather in August
Temperature
Sibley's warmest months, July and August, record an average high-temperature of 91°F (32.8°C).Heat index
For August, the heat index is estimated at a blazing hot 114.8°F (46°C). Take note: Heat exhaustion and heat cramps are expected. Heatstroke can occur with prolonged effort.When referencing the heat index, its values are suitable for shady environments and light breezes. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is found by incorporating humidity levels into the air temperature measurement. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young ones often ignore the need to take a break and drink fluids. Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.
