July averages 90.7°F and August has the warmest ocean of the year at 84.6°F. Rain is heaviest now — 6.39″ in August across about 9.7 wet days — but it arrives as short afternoon storms. Beach in the morning, indoors from three.
Fernandina Beach's busiest and most amenity-heavy oceanfront park, at the east end of Atlantic Avenue. Large free parking lot, restrooms, playground, volleyball, and food and mini-golf across the street — the default choice for a family beach day on Amelia Island.
Nassau County's largest south-end beach park, off Fletcher Avenue near Sadler Road's southern reach. Big free lot, restrooms, outdoor showers, picnic pavilions and a long boardwalk over the dunes — the south end's answer to Main Beach, usually with more room.

Two beaches inside Fort Clinch State Park at Amelia Island's northern tip: Atlantic surf on the east side and calmer water by the jetties on the north, plus a fishing pier looking across Cumberland Sound to Georgia. Inside the park entry fee.

A compact City of Fernandina Beach oceanfront park at the east end of Sadler Road, with a free lot, restrooms, a dune boardwalk and a small playground. The closest full-facility beach to the middle of the island and the usual overflow from Main Beach.
Amelia Island's west side is a maze of tidal creeks and salt marsh feeding the Amelia River, with guided kayak and paddleboard trips running from downtown Fernandina Beach and the south end. Tide timing matters more than fitness here.
Details unconfirmed
Amelia Island offers surf fishing along thirteen miles of Atlantic beach, two long piers over moving water at the island's north and south tips, inshore charters into the marsh and sound, and offshore boats from the Fernandina Harbor Marina.

Amelia Island gets small, inconsistent surf most of the year, with the best waves arriving on winter groundswell and around passing tropical systems. It is a beginner and longboard coast rather than a destination for experienced surfers.
Details unconfirmed
Two hundred undeveloped acres at the island's southern tip on Nassau Sound: beach, dune, marsh and maritime forest, with no buildings and no lifeguards. The only Florida state park offering guided horseback riding on the beach.
A Nassau County beach park at American Beach on the island's south end, with a free lot, restrooms, picnic pavilions and a dune walkover. The practical parking and facilities for anyone visiting American Beach and the NaNa dune.
Summer is peak season and the warmest ocean on the Atlantic coast north of Florida's peninsula: 84.6°F in August. It is also 90.7°F in July with humidity to match, and a hard afternoon thunderstorm most days from June through September.
Both of those are manageable. The shape of a good summer day here is fixed: beach in the morning, indoors or downtown from mid-afternoon.
This matters more in summer than any other season. The tidal range is 6 to 7.4 feet on a very flat beach, so at low water you get hundreds of yards of hard sand and the sandbars exposed for wading — which is the single best thing on this island for small children. At high water on a narrow access there is very little beach at all.
A low-tide morning in July is the best beach experience the island produces. Check today's tides before you load the car.
June to September averages 6.12″, 4.96″, 6.39″ and 7.19″ — but across only about 9 to 10 wet days each. That is convective rain: a hard storm that builds inland, rolls east and clears, rather than all-day drizzle. A 60% chance of rain in a summer forecast usually means one hour of weather somewhere in the afternoon.
They are not harmless. Be off the water by early afternoon — that goes for kayaking, fishing and surfing alike.
Getting children into the ocean. June is the sweet spot: 80.8°F water, small surf, and the warmest the sea gets without July's air temperature.
The water, generally. Water temperature by month holds 76°F or better from May through October.
Sea turtles. Nesting season runs 1 May to 31 October, nesting peaks in early summer, and nests laid in May and June start hatching from July. Dawn walks in August are when you are most likely to see a fresh track. The rules — fill in holes, gear off the beach overnight, lights off the sand — are enforced, and they are a good thing to teach children on a beach holiday.
Fishing. The bait moves and so does everything else. Fish the moving water either side of a tide change; slack high and slack low are the dead hours.
Anything inland and unshaded between eleven and four. The Greenway has no shade at all, and the Fort Clinch ramparts are brick in full sun. Both are excellent at eight in the morning and punishing at two in the afternoon.
July is the busiest month. Everything needs booking, and the lot at Main Beach fills on weekends. Thirteen miles of beach absorbs a lot, though — walk five minutes from any boardwalk and the density drops sharply. See is Amelia Island crowded in summer.
Hurricane season runs 1 June to 30 November, with the statistical peak in early September. That is a season, not a forecast — see our hurricane season guide.
