Clemson, SC

June is typically the gateway into summer in Clemson, South Carolina. The temperature reaches notable highs of 86.5°F (30.3°C), making it a warmer month than May. One can anticipate long sunny days and an extended period of daylight. These conditions accommodate leisurely explorations and a host of outdoor recreational events around the city. However, stay hydrated and protect against the sun as the UV Index touches a lengthier patch of 6 units.

Temperature

With the transition into June, Clemson experiences a subtle uplift in average high-temperatures, adjusting from a moderately hot 78.8°F (26°C) in May to a tropical 86.5°F (30.3°C). A striking difference from the daytime highs is registered during June nights, with an average temperature of 64.9°F (18.3°C).

Heat index

In June, the heat index is evaluated at a sweltering 96.8°F (36°C). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.
When referencing the heat index, its values are suitable for shady environments and light breezes. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', reflects the blend of air temperature and relative humidity to give a temperature impression. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.

Humidity

In June, the average relative humidity is 72%.

Implement preventive steps and embrace sun safety standards. Protection from skin and eye distress is compulsory. Seek shade and limit direct Sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its peak, but be aware that not all shade structures provide complete sun protection. Sunglasses that ward off UVA and UVB rays play a pivotal role in reducing solar eye damage.
