Weather in June
Temperature
With the onset of June, Jamestown's average high-temperature experiences a rise, moving from May's 75.4°F (24.1°C) to a still moderately hot 85.8°F (29.9°C). Jamestown records an average low-temperature of 68.5°F (20.3°C) throughout the month of June.Heat index
June's average heat index is appraised at a sweltering 98.6°F (37°C). Exercise enhanced safety steps, heat cramps and heat exhaustion are probable. Heatstroke could be a result of sustained activity.Heat index readings emphasize conditions of light breezes and shaded spots. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Children commonly overlook the importance of rest and fluid replenishment. Thirst, being a delayed sign of dehydration, emphasizes the need to keep hydration up, especially during lengthy physical activities.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.

Deter overexposure. Protecting against the sun's effects is essential. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes.
