Weather in August
Temperature
Transitioning into August, Grannis experiences an average high-temperature of a still hot 93.2°F (34°C), marking a minor shift from the preceding month. The month of August sees a significant daily temperature drop, recording an average low-temperature of 71.2°F (21.8°C).Heat index
August's average heat index is appraised at a blazing hot 114.8°F (46°C). On guard: Heat exhaustion and heat cramps are predicted. Heatstroke is a potential hazard with continuous physical effort.Bear in mind that the heat index values are determined for shaded areas and light breezes. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.
