Today on the water at St. Simons Light
Today at St. Simons Light: high tide at 12:43 AM (6.7 ft) and 1:13 PM (7.9 ft), low tide at 6:58 AM (0.6 ft) and 7:55 PM (1.1 ft). The National Weather Service forecast for today is chance rain showers with NE winds 10 to 20 mph, 76°F. Wind that strong can hold water in or push it out, so the real tide may run above or below these predictions. In effect now: Small Craft Advisory. Sunrise is at 7:39 AM and sunset at 6:38 PM.
| Period | Forecast | Wind | Temp |
|---|---|---|---|

Where St. Simons Light is
St. Simons Light sits at 31.1317° N, 81.3967° W on the Carolina and Georgia coast on the South Atlantic Bight, at Jekyll Island, GA. The station here is a historical NOAA reference station: a gauge measured the tide at this spot from 1980 until 2008, and NOAA still publishes harmonic predictions from that record. There is no live reading here today. The closest gauge measuring live water level is Kings Bay, Msf Pier (NOAA 8679598), 25.1 mi away, and high and low water here run on average about 36 min earlier than there. The nearest weather station is Brunswick, Malcolm McKinnon Airport, an airport reporting wind, visibility and sky cover, but no water temperature, 1.4 mi away.
The tide at St. Simons Light
St. Simons Light has a semidiurnal tide: two highs and two lows a day of about the same size, roughly 12 hours 25 minutes apart. This month's predictions average 1.9 high tides a day here. The mean range from lower low to higher high is 7.2 ft, and 6.6 ft between the average high and the average low, a large tide. On an average day the higher high tops the lower high by 0.4 ft and the lower low sits 0.2 ft below the other low. For the water around it: Lowcountry tides are semidiurnal, two highs and two lows a day of near equal size, and the range grows toward Georgia, where 6 to 9 ft is normal.
About this station
- High tide reaches St. Simons Light about 0.7 hours after the moon passes overhead. That lag is local, which is why high water does not line up with the moon.
- Highest water on record: 9.6 ft on Jul 22, 2001.
- Lowest on record: -3.3 ft on Mar 8, 2008.
Datum and source
Heights on this page are feet above mean lower low water (MLLW), the zero NOAA's nautical charts use for soundings. A predicted 0.0 ft low is the average of the lower low each day; a minus tide is water below chart datum, and a 2 ft high means 2 ft more water than the chart shows. NOAA fixes MLLW at St. Simons Light from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 7.2 ft above it and mean sea level 3.6 ft. The land survey datum NAVD88, the zero on topographic maps and flood maps, is 4.2 ft above MLLW here, so a water level on this page converts to NAVD88 by subtracting that amount. These datums are controlled from NOAA's Fort Pulaski, GA gauge. Source: NOAA CO-OPS station 8677344, established 1980, gauge removed 2008. The tide times and heights are NOAA's official harmonic predictions for this station; TidalMap republishes them daily and does not alter them.

TidalMapMonthly tide calendar
🌊 Biggest flood tides at St. Simons Light this month: Oct 10, Oct 11, Oct 25, Oct 26, Oct 27, Oct 28, Oct 29, Oct 30. These spring highs push water up into the grass and over the oyster rock; prime for poling into flooded marsh for tailing reds.
🔻 Negative (minus) low tides at St. Simons Light this month: Oct 27, Oct 28. These drain the flats and expose the oyster rock, prime for sight-fishing and clamming.
