Weather in August
Temperature
During August, Cayce observes a subtle ascent to a still tropical 90°F (32.2°C) from July's 91.4°F (33°C) in the average high-temperature. The average temperature in Cayce drops to a pleasant 72.1°F (22.3°C) during the night in the month of August.Heat index
For most parts of August, the heat index is estimated at a scorching 105.8°F (41°C). Adopt additional preventive measures, heat cramps and heat exhaustion are potential outcomes. Prolonged activity may trigger heatstroke.When referencing the heat index, its values are suitable for shady environments and light breezes. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', offers an insight into how hot it feels when we factor in moisture content. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
