Weather in June
Temperature
The shift into June is marked by a modest rise in the average high-temperature, moving from May's moderately hot 82.9°F (28.3°C) to a hot 90.3°F (32.4°C). Throughout June, Union anticipates an average low-temperature of 69.3°F (20.7°C).Heat index
For most parts of June, the heat index is computed to be a blisteringly hot 109.4°F (43°C). Be prepared: Heat cramps and heat exhaustion are probable. Continued activity may lead to heatstroke.Research indicates the heat index considers values in shaded locales and with light winds. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. 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 people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.

A UV Index reading of 6 to 7 represents a high threat to health from unprotected exposure to Sun's UV rays for average individuals.Note: The maximum daily UV index of 7 in June converts into the following recommendations:
Adhere to precautions and respect sun safety doctrines. Avoiding sunburn is vital. 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. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes.
