- ▼ Next low tide 5:56 pm 0.5 ft
↓ Falling The tide is falling. 6 h 3 min to low tide at 5:56 pm.

2026 extremes: the highest tide of the year is on June 16 (6.6 ft) and the lowest, on December 25 (0.0 ft).
Mixed: two high and two low tides a day, but of quite different heights.
Heights above chart datum: the lowest astronomical tide (LAT), the zero of nautical charts in Europe. Astronomical prediction: wind and air pressure can raise or lower the water by a few inches, and more in a storm. Not for navigation. chart datum (LAT)

Where this tide comes from
Wonboyn has no station of its own, so we use the tide at Eden (TICON-4), 12 mi away. On the open coast the difference is usually a few minutes and inches; inside estuaries, rivers and enclosed bays it can be much larger.

The waves you may find
- Most commonMost common2.9 ft
- Significant5.7 ft

One wave in seven is higher than the significant height, and about 3 times a day one reaches 12 ft. Before heading out, expect waves of up to 12 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.

Waves stay much the same all week. The biggest waves arrive on Saturday 31: 6.3 ft with a period of 7 s, from the northeast (moderate).

Surf in Wonboyn today
Surf today
Fair- 2.3–3.5 ft surf at the shore, a fun size for most surfers
- 4.1 ft swell at 6 s from the south-southwest, short: weak, messy waves
- Moderate offshore wind (13 mph): it holds up and grooms the waves
- Rising tide (high tide at 11:04 am)
- Light: First light 5:31 am · sunrise 5:58 am · sunset 7:30 pm · last light 7:58 pm
- Tide: low 4:34 am (1.5 ft), high 11:04 am (5.9 ft) and low 5:56 pm (0.5 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 61.5 °F: a 4/3 fullsuit.
- Energy: 115 kJ · Medium power
Today’s surf at a glance
The best window, 6:00 am to 8:00 am, has a good size and light offshore wind, though with a short-period swell. 2:00 pm to 6:00 pm can also work, with a good size, though with 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.
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 Wonboyn today

- Likely visibility: good. Swell (up to 4.4 ft at 6 s) over the last few days has stirred up the water. Based on the last 24 hours of data.

- Snorkeling: better not, with these waves, wind or current.
- Night dive: dark from 7:58 pm. Waning gibbous (89%), rising at 11:27 pm: a bright night.
Your diving day at a glance
The best window, 9:40 am to 12:30 pm, combines slack water at high tide, weak current and the sun high, though with some swell and fresh wind. Also worth a look from 5:20 pm to 6:30 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 226,459 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: medium- 1:59–3:59 am Major · the moon passes overhead · high activity
- 2:31–4:31 pm Major · the moon passes underfoot · high activity
- 7:08–8:08 am Minor · moonset · medium activity
- 10:57–11:57 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 1,050 ft): 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. 33 ft deep 0.3 mi from shore; 66 ft is far out (1 mi): for deeper dives, 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).
