July weather forecast
Oak Island, NC

As July steps in, Oak Island experiences the highest temperatures of the year ranging from 77.4°F (25.2°C) to 85.6°F (29.8°C). Though temperatures slowly descend from this peak in the following months, the effect of direct sunlight on the human body remains the same due to consistency of the UV index at 7. This period marks the advent of the rainy season with the quantity of rainfall at an annual high of 3.7" (94mm). Despite the copious rainfall, the island's delights aren't dampened as tourists continue to step out, protected by their raincoats and umbrellas. A joint effect of the temperature and rainfall results in increased humidity which can require frequent hydration and cooling off periods, particularly for the unused.

Temperature

The warmest period falls in July and August, when the average high-temperature reaches 85.6°F (29.8°C).

Heat index

Throughout July, the heat index is estimated at a very hot 96.8°F (36°C). Emphasize additional safety, risk of heat cramps and heat exhaustion is high. Continuous activity might result in heatstroke.
Take into consideration that the heat index values are calculated for shade and light wind conditions. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is the outcome of merging air's temperature and its humidity metrics. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young ones regularly neglect the requirement for rest and fluid replenishment. Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.

Note: In July, a daily UV index of 7 turns into the following recommendations:
Inhibit overexposure. Warding off sun damage is of utmost importance. Avoid exposure to the Sun and try to stay in the shade between 10 a.m. and 4 p.m., when UV radiation is most potent, but be aware that parasols or canopies may not offer full protection. Experience reduced UV exposure by about half when donning a wide-brim hat. Heed this! UV intensity is much stronger when reflected off sand and water.
