Weather in August
Temperature
Lancaster experiences an average high-temperature of a still tropical 88.3°F (31.3°C) with the onset of August, subtly varied from July's 90.3°F (32.4°C). Nightly temperatures in Lancaster drop to an average low of 69.8°F (21°C) in August.Heat index
August's mean heat index is calculated to be a sweltering 102.2°F (39°C). Ensure extra safety steps, heat exhaustion and heat cramps are likely. Long activity might lead to heatstroke.From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly important for children. Young ones often do not realize the necessity to rest and replenish their fluids. Thirst is a delayed indication of dehydration - keeping hydrated, particularly in prolonged physical activity, is crucial.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
