June weather forecast
Florence, SC

June in Florence heralds the start of summer and a significant hike in temperatures, compared to its spring predecessor, May. A shift becomes evident in the cloud cover, with fewer clouds seen than in previous months. Among this month's unique features are increased daylight hours, generous sun exposure, and a peak in relative humidity. An exceptional element of weather this month, the Ultraviolet (UV) index leaps to an annual high of 7. This, in combination with predictably light winds, makes a strong case for sunscreen and protective outdoor attire.

Heat index

Be advised, the heat index considers values for conditions in shade and with a light breeze. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', is found by incorporating humidity levels into the air temperature measurement. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
