June weather forecast
Raleigh, NC

June welcomes the peak of summer, with the mercury often rising to the mid-80s. North Carolina's capital experiences its longest daylight hours, giving ample time to enjoy the sun. A notable characteristic of this month is a decrease in wind speed, resulting in calmer days.

The need for a reliable cooling system at home and workplace becomes apparent because of the increasing heat.

Note: The heat index, also known as 'feels like' or 'real feel', is the result of factoring in humidity to the air temperature, indicating perceived warmth. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Kids often lack the knowledge about the necessity to take breaks and consume liquids. Thirst, as a late symptom of dehydration, necessitates the maintenance of hydration, particularly during enduring physical activities.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.
