Weather in June

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

The embrace of June brings a minor uplift in the average high-temperature, shifting from a moderately hot 78.8°F (26°C) in May to a tropical 86.5°F (30.3°C). Clemson records a marked divergence from the day's high temperatures, with nights in June averaging at an enjoyable 64.9°F (18.3°C).

Heat index

During June, the heat index is calculated to be a very hot 96.8°F (36°C). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.
Heat index readings emphasize conditions of light breezes and shaded spots. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', determines the feeling of heat when you account for the relative humidity. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
