June weather forecast
Tulsa, OK

June unfolds summer in Tulsa in all its glory. The weather conditions shift discernibly from spring towards the classic heat of Midwestern US in full swing, peaking at a scorching 86.4°F (30.2°C). From here on, cloud cover diminishes significantly, reaching an annual low, enabling the sunshine to reign supreme. However, rainfall does not cease completely but is intermittently scattered over June, more like summer sprinkles than spring showers. One could argue that June's generous hours of sunshine, paired with the warmth, make it quintessentially "summer" in Tulsa.

Heat index

Bear in mind that the heat index values are determined for shaded areas and light breezes. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is an aggregate value of air's warmth and moisture to show the human-felt temperature. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
