Weather in August
Temperature
The commencement of August brings an average high-temperature of a still warm 81.1°F (27.3°C), marking an inconsequential divergence from July. A marked drop from daytime peak temperatures to an average low-temperature of 58.6°F (14.8°C) is observed during the nights in August.Heat index
The heat index in August is appraised at 82.4°F (28°C). Long-standing exposure coupled with ongoing activity could result in exhaustion, possibly causing heat cramps.Understanding the heat index involves considering values for shaded locales with light wind. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young ones regularly neglect the requirement for rest and fluid replenishment. Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.
