Tides in Tybee Island
Today's high and low tides
- ▼ Next low tide 4:57 am 0.0 ft
- ▲ High tide 10:55 am 8.4 ft · coef. 80
- ▼ Low tide 5:47 pm 0.5 ft
- ▲ High tide 11:18 pm 7.2 ft · coef. 77
↓ Falling The tide is falling. 3 h 43 min to low tide at 4:57 am.
Tide coefficient 80 for the 10:55 am high tide and 77 for the 11:18 pm high tide. Average coefficient. The water rises and falls 8.4 ft between the highest high and the lowest low: a large range for this place. 70 is an average tide here; 90 and above means spring tides; below 45, neap tides. What is the tide coefficient?
2026 extremes: the highest tide of the year is on October 27 (8.7 ft) and the lowest, on December 25 (-1.3 ft).
Semidiurnal: two high and two low tides a day, of similar height.
Heights above mean lower low water (MLLW), the zero of US nautical charts. Astronomical prediction: wind and air pressure can raise or lower the water by a few inches, and more in a storm. Not for navigation. MLLW
Tide coefficient and range in October
The biggest tides of the month came from October 26 to 28 (coefficient 85, 8.7 ft range). The smallest, from October 18 to 19 (coefficient 47, 5.1 ft).

Where this tide comes from
Tides from the Tybee Creek Entrance station (NOAA), 1.2 mi from Tybee Island. Times and heights are its predictions. It is a NOAA subordinate station: its times and heights come from the Fort Pulaski reference station with the official corrections.

The sea at Tybee Island
Sea stateSea state: moderate
The waves you may find
- Most commonMost common2.6 ft
- Significant5.1 ft
- Highest expectedHighest10 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 10 ft. Before heading out, expect waves of up to 10 ft.
Wind on the coast and offshore
Cross-shore wind. The coast faces southeast and the wind blows along the shore: drift and current run parallel to the beach.
Wave height, next 7 daysWaves, next 7 days
Waves stay much the same all week. The biggest waves arrive on Thursday 29: 5.2 ft with a period of 7 s, from the east-northeast (moderate).
Water temperature
Water temperature →Water temperature changes how fish behave: in very cold or very warm water they feed less. The water warms over the next few days: about 71.1 °F by Wednesday 4.

Surf in Tybee Island today
Surf today
Poor- 3.0–4.6 ft surf at the shore, a good size with some punch
- 3.9 ft swell at 7 s from the east, short: weak, messy waves
- Moderate cross-shore wind (15 mph): a bit of chop
- Rising tide (high tide at 10:55 am)
Rip current risk today: high (statement in effect) · tomorrow: high (NWS)
Stay out of the water: rip currents can pull even strong swimmers out to sea. If one catches you, don't swim against it: swim parallel to the shore and wave for help.
Surf height from the NWS, today: 3.0–5.0 ft
- Light: First light 7:13 am · sunrise 7:38 am · sunset 6:36 pm · last light 7:01 pm
- Tide: low 4:57 am (0.0 ft), high 10:55 am (8.4 ft), low 5:47 pm (0.5 ft) and high 11:18 pm (7.2 ft). Every break has its own tide: some work at low tide and others at high tide. The tide doesn’t change the score here.
- Water at 68.0 °F: a springsuit or a 2 mm fullsuit.
- Energy: 164 kJ · Medium power
Today’s surf at a glance
The best window, 9:00 am to 1:00 pm, has a good size, though with a short-period swell and cross-shore wind.
An estimate for this stretch of coast, not for a specific break: every beach or reef works its own way (its tide, bottom and angle). Check it when you get there.
Diving in Tybee Island today
Diving and snorkeling today
Likely visibility: good- Slack water around high tide (10:55 am): little current from 10:20 am to 11:40 am
- 3.7 ft swell at 7 s from the east: some surge on the bottom
- Light cross-shore wind (12 mph)
- 0.1 mph current toward the south, weak (model)
- Sun high: more light underwater
- Slack water today: low tide 4:57 am (4:30–5:12 am), high tide 10:55 am (10:20–11:40 am), low tide 5:47 pm (5:30–6:02 pm) and high tide 11:18 pm (10:50 pm–12:00 am)
- Likely visibility: good. Swell (up to 4.1 ft at 7 s) over the last few days has stirred up the water. Based on the last 24 hours of data.
- Water at 68.0 °F: a 5 mm wetsuit.
- Snorkeling: better not, with these waves, wind or current.
- Night dive: dark from 7:01 pm. Waning gibbous (84%), rising at 9:33 pm: a bright night.
Your diving day at a glance
The best window, 10:20 am to 12:40 pm, combines slack water at high tide, light wind, weak current and the sun high, though with some swell. Also worth a look from 5:10 pm to 6:20 pm, with slack water at low tide and weak current, though with some swell and moderate wind.
Slack water comes from the tide: in inlets, channels and between islands the water can keep running for an hour or two after. Ask the local dive shop.
Never dive alone and check with the local dive shop: this rating is a guide, not a substitute for a professional.

Moon phase and position
Today the moon is 226,746 mi away and looks 32′ 44″ across.
Solunar periods
Today's activity: medium- 3:03–5:03 am Major · the moon passes overhead · high activity
- 3:36–5:36 pm Major · the moon passes underfoot · high activity
- 11:09 am–12:09 pm Minor · moonset · medium activity
- 9:03–10:03 pm Minor · moonrise · medium activity
According to solunar theory, fish feed more when the moon passes overhead or underfoot (major periods, about 2 h) and when it rises or sets (minor periods, 1 h). It works best around new and full moon.

For fishing, swimming and diving
- Shore fishing. Shallow, gradual bottom (16 ft at 3 mi): cast far from the beach and fish the high tide, when there is more water close in.
- Swimming. A very gentle way in with plenty of shallow water, good for kids. At low tide the water can be far out.
- Diving. Shallow: the water doesn't reach 33 ft within 3.1 mi. For deeper dives, take a boat farther out.
