Weather in August
Temperature
August ushers in an average high-temperature of a still moderately hot 82°F (27.8°C), aligning closely with the preceding month. During August, Rathbun consistently records a temperature low averaging an enjoyable 63.5°F (17.5°C).Heat index
Throughout August, the heat index is estimated at a hot 87.8°F (31°C). Continuous exposure and activity could induce a sense of tiredness and subsequently, heat cramps.Heat index readings emphasize conditions of light breezes and shaded spots. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', shows a temperature sensation when both heat and moisture conditions are combined. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly meaningful for babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
