TIDEeye is a web & mobile-friendly tool for keeping an eye on our latest local weather and tides, as well as their impact on our traffic and road closures.
Conditions should be clear most of the time, but when they're not, TIDEeye will use colors to indicate data values that may require close attention. These colors follow the National Weather Service palette for the purpose of continuity.

Flood risk conditions should be clear (blue) most of the time, but look out for other TIDE eye forecasts. These colors follow the National Weather Service palette for the purpose of continuity.
In an effort to better understand the tides and weather that trigger our flooded road conditions, we are actively working to collect more data. If you can contribute by submitting a very brief report, we'd love your help. (Thank you!)
The term "King Tide" is a non-scientific term used to describe Perigean Spring Tides which are the highest seasonal tides that occur each year.
eventPredicted King Tides
The average high tide in Charleston is about 5.5 ft. During a King or Spring Tide event, high tides may reach 7 ft. or higher.
These tides occur when the moon is either new or full and is closest to the earth in its monthly orbit. These especially high tides can cause or worsen coastal flooding. These types of tides are predictable and can be planned for.
NOAA's official Tide Prediction Tables are published annually on October 1, for the following calendar year. Actual water levels will likely vary locally and may be higher than predicted, based on additional weather conditions.
At high tide, much of the stormwater collection system (the pipes and ditches) is already full of sea water leaving little room for the stormwater runoff. The stormwater that has collected on the surface has no place to go because the pipes and ditches are full and ponding occurs.
