Weather in June
Temperature
June's arrival sees a mild rise in the average high-temperature, transitioning from May's moderately hot 84.4°F (29.1°C) to a tropical 91.2°F (32.9°C). During the nights in June, Grayson experiences a consistent average temperature of 71.2°F (21.8°C).Heat index
June's average heat index is computed to be a burning hot 113°F (45°C). Stay watchful: Heat exhaustion along with heat cramps are likely. Ongoing effort may cause heatstroke.Consider that heat index readings are for situations in the shade and light wind. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'apparent temperature' or 'real feel', combines both the air temperature and the humidity level to give a perceived human temperature. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. 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 quite important for children. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.

Exercise precautions and adapt sun safety practices. Defence against skin and eye affliction is paramount. The time between 10 a.m. and 4 p.m. is when UV radiation is at its peak. Limit exposure to direct sunlight during these hours. Equip yourself with UVA and UVB-filtering sunglasses on clear, sunny days.
