On average, high tides will be about 1 foot higher than usual.
For example, in Jacksonville Beach, the average high tide is about 5 feet. But during the morning high tides between Tuesday and Monday — between 8 a.m. and noon — the level will be between 6.3 and 6.6 feet.

Similar conditions, aside from different levels and varying times, will occur along Florida’s entire East Coast.
What causes king tides?
King tides occur when the combined gravitational forces of the sun and moon pull on the Earth’s oceans, creating the highest tides of the year. King tides occur several times a year, most commonly between September and November.
Tidal flooding exacerbates the already rising sea level, which often mixes saltwater with sewage, flooding streets and damaging cars while also posing health risks to those walking through contaminated areas.

You should avoid walking through puddles or flooded roads, as an open wound could be the entry point for a severe infection.
The Atlantic coast will be the most active. Not only will the winds churn the seas, making them hazardous for boaters and swimmers, but the winds coming from the east will also increase the risk of rip currents along the entire coast.
Small craft advisories are up and are very likely to stay in effect for the first half of the week, with the potential to remain in place throughout he latter part of the week. Seas will decrease a bit between Thursday and Friday, but winds will remain strong from the east.
This direct east wind is likely to exacerbate coastal flooding along Florida’s East Coast. Coastal flooding, even if it doesn’t rain, will occur around high tide times.
There is the chance for scattered afternoon storms, which could make flooding worse in some coastal areas if they happen during high tide times.
