Weather in June
Temperature
The arrival of June signals a slight increase in the average high-temperature, moving from a warm 80.2°F (26.8°C) in May to a tropical 87.4°F (30.8°C). During June, Jacksonville witnesses a consistent average low-temperature of 66.2°F (19°C).Heat index
During June, the heat index is evaluated at a very hot 102.2°F (39°C). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', measures the perceived warmth when incorporating the humidity present in the air. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. 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. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.

Steer clear of overexposure. Fair-skinned individuals can be scorched in less than 20 minutes. Between 10 a.m. and 4 p.m., the Sun emits the most powerful UV radiation. Limit direct exposure to the Sun during these hours. Stay sun-safe with clothing that is both closely woven and worn loosely.
