Weather in June
Temperature
Mayport's average high-temperature in June is a tropical 87.6°F (30.9°C), marking an insignificant difference from the 82.9°F (28.3°C) of May. Mayport experiences an average nighttime temperature of 75.2°F (24°C) in the month of June.Heat index
The heat index in June is computed to be a very hot 102.2°F (39°C). Take special precautions - heat exhaustion and heat cramps are expected. Heatstroke may occur with lengthy activity.It is crucial to understand that heat index figures are for shade and gentle wind conditions. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', measures the perceived warmth when incorporating the humidity present in the air. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.

Act on precautions and pay attention to sun safety recommendations. Avoidance of sunburn is obligatory. 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. On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes.
