  • Swimming Calm · 0.4 ft

  • Sun & sunscreen UV 11 · SPF 50

    Max UV 11 (extreme): SPF 50 sunscreen, reapplied every 2 hours. Seek shade 10:00 am–2:00 pm (very high UV).

  • Wind 10 mph

    Offshore breeze (10 mph). Watch floats and inflatables: offshore wind carries them out to sea.

  • Tide & sand 10:11 am

    Low tide at 10:11 am: that's when there's the most sand. High tide at 12:21 am.

Today's high and low tides

  • ▲ High tide 12:21 am 5.2 ft · coef. 81
  • ▼ Low tide 10:11 am 1.7 ft

↑ Rising The tide is rising. 14 h 45 min to high tide at 12:57 am.

Tide coefficient 81 for the 12:21 am high tide. Average coefficient. The water rises and falls 3.5 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 January 4 (7.2 ft) and the lowest, on July 14 (0.1 ft).

Diurnal: one high and one low tide a day most days.

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)

Tide coefficient and range in October

The biggest tides of the month come on October 31 (coefficient 110, 4.6 ft range). The smallest, on October 12 (coefficient 23, 0.5 ft).

Sea and waves

The sea at Alyangula

Waves 0.3 ft · 3.1 s from the northeast (42°)

The waves you may find

One wave in seven is higher than the significant height, and about 3 times a day one reaches 0.6 ft. Before heading out, expect waves of up to 0.6 ft.

Offshore (8.9 mi NE)Offshore 8 mph NNE · gusts 17

Cross-offshore wind. The coast faces west and the wind comes off the land at an angle: calmer water near the shore, and bait and boats drift out to sea.

Today’s surf at a glance

The best window, 5:29 am to 9:00 am, has glassy water, though with barely any waves.

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.

Your diving day at a glance

The best window, 8:40 am to 9:30 am, combines little swell and light wind, though with current. Also worth a look from 2:30 pm to 3:10 pm, with little swell, light wind and the sun high, though with current.

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.

Solunar periods

Today's activity: medium
  • 1:25–3:25 am Major · the moon passes overhead · high activity
  • 1:57–3:57 pm Major · the moon passes underfoot · high activity
  • 7:40–8:40 am Minor · moonset · medium activity
  • 9:16–10:16 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.

Water depth

Shallow, gradual bottom: you need to go 1.4 mi out for 33 ft of water.

From the shoreline (1,100 ft from Alyangula) out to sea, heading west.

How far from shore

  • 16 ft deep0.85 mi
  • 33 ft deep1.4 mi
  • 66 ft deepnot within 3.1 mi
  • 164 ft deepnot within 3.1 mi

For fishing, swimming and diving

  • Shore fishing. Shallow, gradual bottom (16 ft at 0.85 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 1.4 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).
