Weather in July
Temperature
Williamsburg notes the warmest temperatures in July, with a high average of 85.6°F (29.8°C) and a low of 63.5°F (17.5°C).Heat index
July's average heat index is estimated at a fiery hot 96.8°F (36°C). Ensure extra safety steps, heat exhaustion and heat cramps are likely. Long activity might lead to heatstroke.One should consider that heat index numbers are for shaded settings and light wind. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', gauges the sensation of temperature factoring in the air's moisture content. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
