Weather in August
August carries ahead the legacy of July's heat with only a slight decrease in average maximum temperatures. August is synonymous with the last leg of peak summer days in Garner, with some of July's hottest spells spilling into the month. Despite the soaring temperatures, the month witnesses an increase in rainfall to 3.43" (87mm), which marks the highest rainfall for the second half of the year. A marginal reduction in daylight hours and equally long sunny days contribute to the characteristic late summer weather. As the sun slowly begins to set on summer, the wind and humidity levels follow suit and prepare to welcome the arrival of autumn.Temperature
With the advent of August, Garner's high-temperatures adjust to a still hot 87.3°F (30.7°C), closely aligning with the preceding month. During the month of August, an average low-temperature of 69.4°F (20.8°C) is recorded.Heat index
For most parts of August, the heat index is computed to be a fiery hot 100.4°F (38°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a composite of temperature and humidity figures to convey how warm it feels. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
One of the main methods the human body employs to cool down is by perspiring, as this process allows sweat to evaporate and remove excess heat. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
