As June arrives, Key's weather shows a minor increase in high-temperatures, edging from May's moderately hot 79.3°F (26.3°C) to a hot 86.5°F (30.3°C). Key, in June, experiences an average temperature of 65.8°F (18.8°C) at night.Heat index
June's average heat index is estimated at a very hot 98.6°F (37°C). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.One should consider that heat index numbers are for shaded settings and light wind. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', embodies the combination of air temperature and moisture content to illustrate perceived heat. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.

Refrain from overexposure. Fair-skinned individuals could burn in under 20 minutes. Avoid direct sunlight between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. Keep in mind that shade structures may not provide complete protection. Limit sun-induced ocular harm with sunglasses that feature UVA and UVB filtration.
