Weather in June

The first month of the summer, June, is a hot month in Siler City, North Carolina, with an average temperature varying between 65.8°F (18.8°C) and 86.4°F (30.2°C).

Temperature

In Siler City, the onset of June comes with a modest high-temperature shift, transitioning from May's warm 78.6°F (25.9°C) to a tropical 86.4°F (30.2°C). Siler City's average low-temperature in the month of June is recorded at a comfortable 65.8°F (18.8°C).

Heat index

In June, the heat index is computed to be a torrid 96.8°F (36°C). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.
It is important to note that the heat index values are for shaded areas and light wind scenarios. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', shows a temperature sensation when both heat and moisture conditions are combined. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. 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. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
