March may not sound like the most popular month to visit Florida for beach vacation. But in fact, if you know where to go, you can enjoy the state’s warm weather on some of the best Florida beaches and even have a very pleasant dip in the ocean.
In this article I’ll share with you the warmest beaches in Florida in March. In general, for the warmest weather and the warmest water temperature, you need to head to South Florida on the Atlantic Coast. Anywhere from the Florida Keys to Jupiter, including all the major destinations like South Beach, Key West, Hollywood Beach, Fort Lauderdale, and Palm Beach should be fine.
How Warm the Water in Florida in March Will Be?
The water in Florida in March won’t be balmy but it won’t be cold. For most people, water temperatures above 73 °F (the average for March at many South Florida Beaches) are fine for bathing without a wetsuit. You may need a minute or two to get used to the water. But afterward, you can stay comfortably, particularly when moving around, for at least 1-2 hours.
Temperatures above 77 °F, the maximum in March for even the warmest Florida beaches, are comfortable for almost everyone, barring those who get cold easily. If the weather is particularly warm and the Atlantic Ocean heats up as well, you’ll have a very enjoyable beach day.
Temperatures above 81 °F start to get very balmy. But such water temperatures don’t come to the Sunshine State until May/June.
Top 7 Warmest Beaches in Florida in March
Here are your best options to have a pleasant dip in the ocean and not freeze while relaxing at the beach. As an extra tip, if you want to go in March, it’s better to go in early March, before the spring break chaos ensues at many beaches of South Florida.

New Smyrna Beach and Daytona Beach will already be much cooler (62.4 and 67.3 °F) while Jacksonville will be outright cold (58.1 and 63.2 °F).
The Gulf Coast is also not such a great idea. It will be much colder than the Atlantic Ocean, including in Naples, Cape Coral, Fort Myers (65.3 and 70.8 °F) and further north in Venice, Sarasota, or Clearwater Beach (64 and 69.4 °F).
Northwest Florida, with places like Panama City Beach or Destin (61.5 and 66.3 °F), is only suitable for beach vacation in the summer.
