Weather in June
Temperature
The shift from May to June is marked by an increase in the average high-temperature, moving from 74.8°F (23.8°C) to a still warm 84.7°F (29.3°C). During June, Jamestown experiences an average low-temperature of 65.1°F (18.4°C) at night.Heat index
In June, the average heat index is appraised at a very hot 95°F (35°C). Take more preventive steps, risk of heat exhaustion and heat cramps is elevated. Long activity may culminate in heatstroke.The metrics for the heat index are tailored for both shady environments and light winds. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'real feel' or 'apparent temperature', joins air temperature with relative humidity to produce a temperature perception for humans. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

Shun overexposure. Protection from sun ravages is indispensable. Avoid direct sunlight between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. Keep in mind that shade structures may not provide complete protection. Sunglasses that ward off UVA and UVB rays play a pivotal role in reducing solar eye damage.
