Editorial

About tides at Charleston, SC

A short guide to the coastline at Charleston, SC — geography, sea state, and what the tide is actually doing under your feet.

Charleston Harbor opens to the Atlantic between Sullivan's Island and Morris Island, with the Cooper and Ashley rivers feeding the inner harbour. 7 metres — a textbook semidiurnal pattern, two highs and two lows of similar size each day. 4 metres.

The Battery, Shem Creek, and the marshes behind Folly Beach all swing through the full range, and the marsh creeks behind the barrier islands run hard on each ebb. For paddlers, anglers fishing the inlets, or families combing Folly's intertidal zone for shells, the timing and size of the low matters. Hurricane season — June through November — can stack water surge of 1–2 metres on top of predicted tides; that's when local emergency-management forecasts override harmonic predictions completely.

Predictions on this page come from NOAA CO-OPS station 8665530 in Charleston Harbor.

Common questions

Tide questions about Charleston, SC

Quick answers to the most common questions about tide times, range, and water access at Charleston, SC.

When is the next high tide at Charleston?

The hero block shows the next high tide at Charleston Harbor in local Eastern time. The 7-day table covers all daily extremes. For tropical-storm and hurricane surge potential, the National Hurricane Center and the Charleston NWS office are the authoritative real-time sources.

What's the typical tide range at Charleston?

Mean range is about 1.7 metres at Charleston Harbor — semidiurnal, with two highs and two lows of comparable size. Spring tides push to roughly 2.0 metres, neaps compress to about 1.4 metres. Wind setup from the southeast can lift water levels by 20–30 cm even in fair weather; tropical-storm surge can lift them several metres.

When are the best low tides for shell-hunting on Folly Beach?

The lowest tides cluster around new and full moons. Folly's intertidal zone widens noticeably on the lowest predicted tides — under 0.3 m above MLLW makes the wash zone walkable for an hour or so either side. The 7-day table flags each day's predicted low. Pair with sunrise from the sun/moon block above for first-light combing.

Where do these tide predictions come from?

NOAA CO-OPS station 8665530, Charleston Harbor. The station has a long historical record, and NOAA's harmonic predictions for it are very high accuracy under normal conditions — typically within a few minutes and a few centimetres of measured water level.

Is this safe to use for navigation?

No. Use NOAA's authoritative tide and chart products plus US Coast Guard notices for piloting in Charleston Harbor and the Intracoastal Waterway. Hurricane and tropical-storm surge can completely override predicted levels — emergency-management forecasts take precedence in those events.
