Weather in June
Temperature
As June arrives, a slight rise in the average high-temperature is observed, moving from an agreeable 72.7°F (22.6°C) in May to a moderately hot 81°F (27.2°C). June's nights observe an average temperature of 64°F (17.8°C).Heat index
June's heat index is calculated to be a hot 86°F (30°C). When exposure and activity are sustained, they could induce fatigue, with a chance of heat cramps.Know that the heat index computations account for shaded terrains and slight winds. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.

Exercise precautions and adapt sun safety practices. Defence against skin and eye affliction is paramount. Stay out of direct sunlight between 10 a.m. and 4 p.m., when UV radiation is most intense, and remember that not all shade structures provide complete protection. Sunglasses that guard against UVA and UVB rays are pivotal in minimizing sun-induced ocular damage.
