Weather in August

August, the last month of the summer in Rockcrest, is also a moderately hot month, with an average temperature fluctuating between 85.3°F (29.6°C) and 67.5°F (19.7°C).

Temperature

The onset of August marks an average high-temperature of a moderately hot 85.3°F (29.6°C), hardly differing from July's 87.1°F (30.6°C). Rockcrest experiences an average low-temperature reading of 67.5°F (19.7°C) throughout August.

Heat index

The heat index value during August is evaluated at a torrid 95°F (35°C). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.
It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', arises from combining readings of air temperature and relative moisture content. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
