Weather in August
Temperature
The transition into August marks the average high-temperature at a moderately hot 84.7°F (29.3°C), differing minimally from July's 86.5°F (30.3°C). In Hecker, an average temperature of 66°F (18.9°C) is noted during August nights.Heat index
The heat index value during August is evaluated at a fiery hot 95°F (35°C). Implement additional cautionary measures, heat cramps and heat exhaustion could occur. Prolonged activity might induce heatstroke.Take note of the fact that heat index values are based on shaded circumstances with light airflows. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.

Shield from overexposure. Defense against sun-related harm is required. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. In the presence of strong sunlight, it's crucial to wear sunglasses that ward off UVA and UVB rays.
