Temperature

The rise of average high-temperatures is seen in June, with an increase from a warm 81.5°F (27.5°C) in May to a tropical 90.9°F (32.7°C). Throughout the month of June, Plano expects an average low of 73.2°F (22.9°C).

Heat index

Throughout June, the heat index is calculated to be a scorching 105.8°F (41°C). Ensure additional precautions, heat exhaustion and heat cramps may be expected. Heatstroke could occur from sustained activity.
Always consider that heat index estimations are for light winds and places in the shade. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is found by incorporating humidity levels into the air temperature measurement. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
Humans rely on perspiration as a cooling mechanism, wherein the evaporating sweat counteracts excessive warmth. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
