Weather in July

July, the same as June, is a moderately hot summer month in Onancock, Virginia, with an average temperature fluctuating between 75.7°F (24.3°C) and 82°F (27.8°C).

Temperature

July is the warmest month, with an average high-temperature of 82°F (27.8°C) and an average low-temperature of 75.7°F (24.3°C).

Heat index

For most parts of July, the heat index is computed to be a hot 87.8°F (31°C). Ongoing activity coupled with exposure often results in weariness and could induce heat cramps.
Understanding the heat index involves considering values for shaded locales with light wind. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', joins air temperature with relative humidity to produce a temperature perception for humans. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.

Note: The daily high UV index of 7 during July translates into the following recommendations:
Apply measures and align with sun safety principles. Safeguarding against skin and eye injury is pivotal. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. For effective sun eye protection, rely on sunglasses certified for UVA and UVB resistance.
