June weather forecast
Riverdale, FL

June, the first month of the summer in Riverdale, is still a hot month, with an average temperature fluctuating between 88.7°F (31.5°C) and 73.9°F (23.3°C).

Temperature

The beginning of June reveals an average high-temperature of a still hot 88.7°F (31.5°C), showing minimal deviation from the previous month. During June, Riverdale sees a mean low-temperature of 73.9°F (23.3°C).

Heat index

In June, the average heat index is computed to be a scorching 107.6°F (42°C). Exercise increased caution, heat cramps and heat exhaustion are potential hazards. Continuous activity could lead to heatstroke.
Heat index values are typically calculated for conditions of shade and a light breeze. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', arises from combining readings of air temperature and relative moisture content. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Humidity

The average relative humidity in June is 78%.

Note: In June, a daily UV index of 7 turns into the following recommendations:
Take precautions against overexposure. Protection against sun damage is needed. Limit direct sun exposure especially between 10 a.m. and 4 p.m., when UV radiation is at its peak. However, keep in mind that shade structures may not provide full sun protection. Outfit yourself in sun-safe attire, like long sleeves, pants, a hat, and UV-blocking sunglasses.
