↑ Rising The tide is rising. 5 h 35 min to high tide at 6:00 am.

Tide coefficient 92 for the 6:00 am high tide and 87 for the 6:29 pm high tide. Spring tides. The water rises and falls 14.8 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 March 20 (18.6 ft) and the lowest, on August 14 (1.0 ft).

Semidiurnal: two high and two low tides a day, of similar height.

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 came from October 26 to 28 (coefficient 100, 15.9 ft range). The smallest, on October 19 (coefficient 26, 4.8 ft).

How we calculate the tide

Sea and waves

The sea at Arzon

7-day waves

Sea stateSea state: slight

Slight Douglas 3 · gentle breeze, Beaufort 3
Waves 3.8 ft · 10.8 s from the west (264°)
Swell 3.8 ft · 9.1 s from the west
Current 0.2 mph toward the W

The waves you may find

  • Most commonMost common1.9 ft
  • Significant3.8 ft
  • Highest expectedHighest7.5 ft

One wave in seven is higher than the significant height, and about 3 times a day one reaches 7.5 ft. Before heading out, expect waves of up to 7.5 ft.

Wind on the coast and offshore

On the coast 5 mph NE · gusts 6
Offshore (5.9 mi SW)Offshore 8 mph ENE · gusts 11

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

Water temperature changes how fish behave: in very cold or very warm water they feed less. The water is steady these days, with no sudden changes.

Water colder than normal for late October (−2.5 °F).

Your diving day at a glance

The best window, 12:30 pm to 1:30 pm, combines slack water at low tide, light wind, weak current and the sun high, though with some swell. Also worth a look from 5:10 pm to 6:30 pm, with slack water at high tide and light wind, 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.

Never dive alone and check with the local dive shop: this rating is a guide, not a substitute for a professional.

Solunar periods

Today's activity: medium
  • 2:37–4:37 am Major · the moon passes overhead · high activity
  • 3:10–5:10 pm Major · the moon passes underfoot · high activity
  • 11:49 am–12:49 pm Minor · moonset · medium activity
  • 7:30–8:30 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

Shallow, gradual bottom: 16 ft at 0.9 mi from shore and 18 ft at 3.1 mi.

From the shoreline (0.8 mi from Arzon) out to sea, heading south.

How far from shore

  • 16 ft deep0.9 mi
  • 33 ft deepnot within 3.1 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 0.9 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.

Inside bays, estuaries and harbors the bottom changes a lot from spot to spot (channels and shoals): use this only as a rough guide.
