Weather in June
Temperature
As Stillwater transitions into June, the average high-temperature shows a change, moving from a moderately hot 77°F (25°C) in May to a tropical 88°F (31.1°C). Stillwater records a consistent low-temperature of 69.8°F (21°C) during June nights.Heat index
June's average heat index is appraised at a fiery hot 100.4°F (38°C). Incorporate additional safety actions, heat cramps and heat exhaustion are possible. Long-term activity may induce heatstroke.Metrics for the heat index primarily focus on shaded spots and light wind conditions. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are especially vital to children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
