June weather forecast
Bethany, OK

June ensures the full arrival of summer in Bethany with the mercury rising to even higher levels. The wet May weather makes way for a drier atmosphere, contributing to the decreased levels of relative humidity. This month showcases the longest daylight hours with the sun shining brightly for nearly half the day. Between the plentiful sunshine, gentle breezes and an average rainfall lower than that of May, June presents itself with typically summer weather characteristics. It's the perfect time for residents to dive into their favourite summer activities or plan a beach day.

Temperature

Entering June, Bethany sees a temperature rise, with the average high-temperature advancing from May's warm 77.9°F (25.5°C) to a tropical 89.1°F (31.7°C). In June, Bethany's temperature tends to fall to an average low of 70.3°F (21.3°C) during the night.

Heat index

June's average heat index is appraised at a fiery hot 102.2°F (39°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.
The standards for the heat index are set for locations in shade and under light breezes. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a measure of how hot it feels when the actual air humidity is factored in. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

Humidity

In Bethany, the average relative humidity in June is 67%.

Rainfall

UV index

June through August, with an average maximum UV index of 7, are months with the highest UV index. A UV Index reading of 6 to 7 represents a high threat to health from unprotected exposure to Sun's UV rays for average individuals.
Note: A daily high UV index of 7 in June leads to these guidelines:
Sidestep overexposure. Individuals with fair complexions risk burning in fewer than 20 minutes. Avoid direct Sun exposure and seek shade from 10 a.m. to 4 p.m., the period of highest UV radiation. Remember, however, that not all shade structures offer full protection. Wearing sunglasses with both UVA and UVB protection effectively reduces sun-induced eye damage.
