Weather in August
Temperature
The advent of August reveals an average high-temperature of a still tropical 86.2°F (30.1°C), showing minimal difference from the prior month. In Smithfield, the average temperature during the nights of August drops to an agreeable 71.2°F (21.8°C).Heat index
The average heat index in August is computed to be a very hot 96.8°F (36°C). Ensure additional precautions, heat exhaustion and heat cramps may be expected. Heatstroke could occur from sustained activity.In terms of the heat index, values are set with light wind and shade conditions in mind. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', marries air temperature and humidity to produce a value illustrating perceived warmth. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Children commonly overlook the importance of rest and fluid replenishment. Thirst, being a delayed sign of dehydration, emphasizes the need to keep hydration up, especially during lengthy physical activities.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
