Actual nearshore water temperatures may fluctuate by several degrees from the reported values, especially following heavy rainfall or extended periods of strong winds. Certain wind patterns can cause colder, deeper waters to rise and replace the sun-warmed surface water, leading to noticeable variations.
Our forecast is based on a proprietary mathematical model that considers real-time water temperature changes, historical trends, key weather patterns, wind strength and direction, and air temperature specific to each region. Additionally, we incorporate data from other resorts to enhance accuracy.

In the spring and summer, the water temperature of the St. Johns River can rise significantly, typically reaching between 75°F (24°C) and 85°F (29°C), making it ideal for swimming and other water-based recreation.

The slower-moving sections of the river near Deltona are more suitable for swimming, though, like many other natural bodies of water, there can be concerns about water quality, especially after rainfall or during algal blooms.
While the St. Johns River offers a great opportunity for swimming in the warmer months, it is essential to be mindful of its natural conditions.
