July weather forecast
Riverdale, FL

July, like June, is another hot summer month in Riverdale, Florida, with an average temperature fluctuating between 89.6°F (32°C) and 74.8°F (23.8°C).

Temperature

The average high-temperature during July registers at a still hot 89.6°F (32°C), maintaining a close resemblance to the previous month. Throughout July, the temperature tends to fall to a consistent average low of 74.8°F (23.8°C).

Heat index

The heat index value for July is estimated at a blistering 111.2°F (44°C). On guard: Heat exhaustion and heat cramps are predicted. Heatstroke is a potential hazard with continuous physical effort.
The metrics for the heat index are tailored for both shady environments and light winds. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', blends air temperature and moisture content to represent the felt temperature to humans. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Humidity

July through September, with an average relative humidity of 79%, are the most humid months in Riverdale.

Rainfall

In Riverdale, in July, it is raining for 20.8 days, with typically 2.64" (67mm) of accumulated precipitation. In Riverdale, Florida, during the entire year, the rain falls for 140.2 days and collects up to 15" (381mm) of precipitation.

UV index

The months with the highest UV index are May through September, with an average maximum UV index of 7. A UV Index of 6 to 7 symbolizes a high health risk from unprotected exposure to Sun's UV rays for ordinary individuals.
Note: The daily high UV index of 7 in July translates into this advice:
Take precautions against overexposure. Protection against sun damage is needed. Avoid direct exposure to the Sun between 10 a.m. and 4 p.m., the peak period for UV radiation, noting that objects like parasols or canopies might not offer complete sun protection. To mitigate harm from sun exposure, pick sunglasses offering UVA and UVB defense.
