Georgia Tide Charts

Q: Where do the Georgia tide predictions come from?

Every value comes from NOAA's Center for Operational Oceanographic Products and Services (CO-OPS). Georgia has 5 harmonic prediction stations in this directory, and each page requests the predictions from api.tidesandcurrents.noaa.gov in your browser when it loads, so the numbers are NOAA's own rather than a copy we maintain.

Q: Which Georgia station has the biggest tides?

Among the stations listed here, Brunswick has the largest published mean range at 7.13 feet, while St. Marys has the smallest at 5.86 feet. Mean range is NOAA's long-term average difference between mean high water and mean low water; spring tides swing wider than it and neap tides narrower.

Q: Why is high tide at different times along the Georgia coast?

The tide is a long wave moving along the coast and into every bay and river, and it takes real time to travel. Two towns on the same shoreline can see high water an hour or more apart, and the delay grows up estuaries and behind inlets. That is why this page links a separate chart per NOAA station instead of pretending one table covers the whole state.

Q: Can I use these pages for boating in Georgia?

No. These are planning pages for beach walks, fishing and tidepooling. Mariners should use official NOAA charts and products at tidesandcurrents.noaa.gov. Whether any specific flat, bar or crossing is safe on foot is a local conditions question for the authority that manages that shoreline, not something a tide table can answer.

NOAA station classification

Georgia’s short coast has some of the biggest tides on the Atlantic seaboard south of New England: the coastline’s concave curve funnels the tide into ranges that routinely astonish visitors. The Golden Isles’ huge marshes flood and empty on that swing twice a day.

Each page below reads NOAA’s harmonic predictions live for one station: today’s curve, a 7 day high/low table with sun and moon times, and the week’s best low tide windows. Mean range and tide type come from NOAA’s published station datums, and they are worth a glance before you pick: two towns an hour apart can live on very different tides.

Mean range is NOAA’s published difference between mean high water and mean low water at each station, in feet.

Local knowledge

How tides behave on the Georgia coast

At low tide the beaches at Tybee, St. Simons and Cumberland grow enormous, and sandbars connect and disconnect fast enough to strand the unwary, which is why every local checks the chart before walking out. Anglers fish the last of the falling water in the sounds.

The spread inside the state is real: NOAA’s mean range runs from 5.86 feet at St. Marys to 7.13 feet at Brunswick. Use the station nearest the shoreline you actually plan to stand on, and expect timing to drift further up rivers, estuaries and back bays.
