Weather in June
Temperature
As June sets, the average high-temperature shows an increase, moving up from a moderately hot 76.6°F (24.8°C) in May to a still warm 85.8°F (29.9°C). Unionville experiences an average low-temperature of 66.4°F (19.1°C) in month of June.Heat index
Throughout June, the heat index is computed to be a torrid 96.8°F (36°C). Implement more safety precautions, heat cramps and heat exhaustion may happen. Persistent activity could induce heatstroke.Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'feels like' or 'felt air temperature', combines both the air temperature and the humidity level to give a perceived human temperature. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
