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.

Temperature

June signals a shift in the average high-temperature, moving from May's moderately hot 76.1°F (24.5°C) to a hot 86.4°F (30.2°C). Throughout June, the nighttime temperature averages to an agreeable 69.3°F (20.7°C).

Heat index

The average heat index in June is calculated to be a very hot 98.6°F (37°C). Incorporate extra safety measures to avoid heat exhaustion and heat cramps. Continuous activity could provoke heatstroke.
Be aware that heat index ratings are designed for shaded locations and minor 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 'feels like', evaluates the perceived heat by adding the effect of moisture in the air. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. When there is an excess of moisture in the atmosphere, the efficiency of the evaporation process is lessened, leading to less efficient body cooling and a sensation of overheating. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.

Enforce precautions and stick to sun safety measures. Preservation from skin and eye damage 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. It's wise to wear UVA and UVB-blocking sunglasses when the sun shines brightly.
