Where this tide comes from
Tides from the Port Elizabeth station (TICON-4), 0.9 mi from Gqeberha. Times and heights are its predictions.

The sea at Gqeberha
Sea stateSea state: slight
The waves you may find
- Most commonMost common2.0 ft
- Significant4.0 ft
- Highest expectedHighest8.0 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 8.0 ft. Before heading out, expect waves of up to 8.0 ft.
Wind on the coast and offshore
Cross-offshore wind. The coast faces east and the wind comes off the land at an angle: calmer water near the shore, and bait and boats drift out to sea.
Wave height, next 7 daysWaves, next 7 days
Waves build over the next few days. The biggest waves arrive on Thursday 29: 8.5 ft with a period of 10 s, from the south-southeast (rough).
Water temperature
Water temperature →The satellite measured 2.9 °F more yesterday than the model gives now: the water is probably warmer than the forecast says.
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 68.4 °F by Tuesday 3.
Water warmer than normal for late October (+1.8 °F).

Surf in Gqeberha today
Surf today
Fair- 2.4–3.6 ft surf at the shore, a fun size for most surfers
- 3.3 ft swell at 6 s from the east-southeast, short: weak, messy waves
- Light offshore wind (11 mph): it holds up and grooms the waves
- Rising tide (high tide at 4:48 pm)
- Light: First light 4:55 am · sunrise 5:21 am · sunset 6:42 pm · last light 7:08 pm
- Tide: high 4:36 am (6.0 ft), low 10:32 am (0.8 ft), high 4:48 pm (6.3 ft) and low 11:03 pm (0.7 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 65.3 °F–66.7 °F: a 3/2 fullsuit.
- Energy: 83 kJ · Low power
Today’s surf at a glance
The best window, 1:00 pm to 5:00 pm, has a good size and light offshore wind, though with a short-period swell.
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.
Follow the flags and the lifeguards, and don’t paddle out if the surf is above your level: this score is a guide, not a substitute for what you see when you get there.
Diving in Gqeberha today
Diving and snorkeling today
Likely visibility: good- Slack water around low tide (10:32 am): little current from 10:10 am to 10:50 am
- 4.1 ft waves: careful getting in and out
- Light offshore wind (10 mph)
- 0.4 mph current toward the northeast, weak (model)

- Likely visibility: good. Swell (up to 4.7 ft at 6 s) over the last few days has stirred up the water. Based on the last 24 hours of data.
- Water at 65.3–66.7 °F: a 5 mm wetsuit.
- Snorkeling: better not, with these waves, wind or current.
- Night dive: dark from 7:08 pm. Waning gibbous (93%), rising at 9:47 pm: a bright night.
Your diving day at a glance
The best window, 9:40 am to 11:20 am, combines slack water at low tide, light wind, weak current and the sun high, though with waves. Also worth a look from 4:10 pm to 5:20 pm, with slack water at high tide, light wind and weak current, though with waves.
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 226,471 mi away and looks 32′ 46″ across.
Solunar periods
Today's activity: high- 12:35–2:35 am Major · the moon passes overhead · high activity
- 1:06–3:06 pm Major · the moon passes underfoot · high activity
- 6:01–7:01 am Minor · moonset · medium activity
- 9:17–10:17 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 0.5 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 near shore: you only reach 33 ft at 0.75 mi. For dives deeper than 33 ft, go by boat.
Rough estimate: here the data comes in cells of about 0.3 mi and misses details near shore (rocks, sandbars, small coves).
