Weather in August
Temperature
With the advent of August, Jeff experiences an average high-temperature of a still moderately hot 84.2°F (29°C), mirroring a close resemblance to the previous month. Jeff observes a noteworthy temperature drop from the daily highs during August nights, with a mean temperature of 61°F (16.1°C).Heat index
August's average heat index is evaluated at a tropical 93.2°F (34°C). Implement enhanced safety actions, heat cramps and heat exhaustion could occur. Sustained activity might result in heatstroke.Consider that heat index readings are for situations in the shade and light wind. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
