Weather in August
Temperature
Rockcrest observes a minor difference in average high-temperatures between July's 87.1°F (30.6°C) and August's 85.3°F (29.6°C). During the month of August, the nighttime temperature falls to an average of 67.5°F (19.7°C).Heat index
Throughout August, the heat index is estimated at a torrid 95°F (35°C). Ensure extra safety measures, heat exhaustion and heat cramps are likely. Continuous activity might result in heatstroke.Realize that the values for the heat index are set for shaded places and light winds. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', melds the effects of warmth and moisture to generate a feeling of heat. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. 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 of high significance for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
