That is about 5°F warmer than average for this time of year, and warming over the last two weeks. The November average here is 73°F.
Updated Saturday, November 7 — sea-surface temperature modeled for Bradenton Beach by Open-Meteo.
Out in the open Gulf, NOAA buoy 42098 — 16 miles offshore — is reading 77°F. Deep water offshore runs cooler than the shallows in summer and warmer in winter, so it won't match the beach.
For swimming
Warm
About as good as it gets — warm enough to stay in for hours without getting chilled.
For fishing
Peak season
Snook, redfish and tarpon are all active and feeding. The tarpon migration through the passes runs at the upper end of this range.

The water at Bradenton Beach
Bradenton Beach anchors the south end of Anna Maria Island, with the grass flats of Sarasota Bay and Palma Sola on the inside and Longboat Pass cutting through to the Gulf. Trout and redfish are the bread-and-butter over the grass, snook hold to the pass and pier pilings, and flounder ambush bait along the sandy edges. It's classic west-central Florida flats water.
Anna Maria Sound & the Gulf
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 Bradenton Beach; expect the back bays to be a few degrees either side of it depending on the season.
Common questions
- What is the water temperature at Bradenton Beach right now?
- The water at Bradenton Beach is currently about 78°F (26°C). The November average here is 73°F.
- Is the water warm enough to swim at Bradenton Beach in November?
- November averages 73°F at Bradenton Beach, which most people would call cool but comfortable. Refreshing rather than cold — comfortable once you're past the first minute.
- When is the water warmest at Bradenton Beach?
- July is the warmest month on average at 89°F, and January the coolest at 63°F. 7 months of the year average 75°F or above.
- 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. A strong winter cold front can pull the inshore water down several degrees in a couple of days, and a sustained offshore wind can drop beach temperatures in a single morning by pulling cooler water up from below.
