June weather forecast
Cary, NC

June ushers in the summer season with a noticeable rise in temperature. Despite recording 2.91" (74mm) of rainfall, June showcases a relatively lower humidity of 72% compared to other months. Warmer temperatures and longer days are welcoming for a myriad of outdoor activities, including beach visits due to close proximity of Cary to North Carolina's coast. Nonetheless, the elevated UV index indicates the need for appropriate sun protection during sunshine hours. This period is also the onset of the hurricane season, thus locals and visitors are advised to monitor weather updates frequently.

Temperature

As May transitions into June, Cary notices a gentle rise in the average high-temperature, transitioning from a warm 78.6°F (25.9°C) to a hot 86°F (30°C). During June, the temperature tends to dip to an average of 67.5°F (19.7°C) at night.

Heat index

During June, the heat index is computed to be a very hot 96.8°F (36°C). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.
Heat index guidelines indicate values are for light wind scenarios and shaded regions. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', comes about by integrating the temperature readings with the humidity levels. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
One of the main methods the human body employs to cool down is by perspiring, as this process allows sweat to evaporate and remove excess heat. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.

Note: The UV index of 6 during June leads to these advisories:
Conform to measures and uphold sun safety traditions. Warding off skin and eye harm is necessary. Limit your exposure to the sun's UV radiation, which is strongest between 10 a.m. and 4 p.m., and note that parasols or canopies may not provide full sun protection. For holistic sun protection encompassing the eyes, ears, face, and neck, a wide-brim hat is key.
