Weather in August
Temperature
Smithfield commences August with an average high-temperature of a still hot 86.5°F (30.3°C), maintaining a close resemblance to the previous month. Nighttime temperature lowers to an average of 69.6°F (20.9°C) in August.Heat index
The heat index value for August is calculated to be a torrid 100.4°F (38°C). Adopt additional preventive measures, heat cramps and heat exhaustion are potential outcomes. Prolonged activity may trigger heatstroke.Take note of the fact that heat index values are based on shaded circumstances with light airflows. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', measures the perceived warmth when incorporating the humidity present in the air. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are extremely significant for babies and toddlers. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
