Weather in June
Temperature
The shift from May to June is marked by a slight increase in the average high-temperature, moving from a moderately hot 80.4°F (26.9°C) to a tropical 89.1°F (31.7°C). Throughout the nights in June, Old Union experiences an average low-temperature of 68.5°F (20.3°C).Heat index
The heat index value during June is estimated at a scorching 105.8°F (41°C). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.Realize that the values for the heat index are set for shaded places and light winds. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'feels like', ties air temperature with relative humidity to produce the perceived temperature sensation. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.

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.
