The water at Melbourne Beach · Indialantic
Melbourne Beach and Indialantic sit on the narrow barrier island where the Indian River Lagoon runs closest to the Atlantic, so the two fisheries are minutes apart. The beach break at the Indialantic boardwalk is the local surf spot and a good snook and pompano beach; a few blocks west, the lagoon's grass flats and dock lines hold trout, redfish, and black drum. Sea turtles nest heavily along this stretch in summer.

What moves the water temperature here
The Gulf shelf off this coast is shallow, which is why the water swings so much more between summer and winter than open ocean at the same latitude does. Shallow water heats fast and gives that heat up fast: a single strong winter cold front can pull the inshore bays several degrees down in a couple of days, while the beaches a mile offshore barely move. Wind direction matters too — a sustained offshore breeze can pull cooler water up from below and drop the beach temperature noticeably in a morning.
Inshore bays, canals and flats run warmer than the beach through the summer and colder through the winter, for the same reason. The reading above is for the open water at Melbourne Beach · Indialantic; expect the back bays to be a few degrees either side of it depending on the season.

- Why does the water temperature change so quickly here?
- The Gulf shelf off this coast is shallow, so it heats and cools far faster than deep open ocean.
