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)

Where this tide comes from
Ferrol has no station of its own, so we use the tide at A Coruña (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 sea at Ferrol
Sea stateSea state: moderate
The waves you may find
- Most commonMost common3.9 ft
- Significant7.7 ft
- Highest expectedHighest15 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 15 ft. Before heading out, expect waves of up to 15 ft.
Wind on the coast and offshore
Offshore wind. The coast faces south and the wind blows from land out to sea: calm shore and clean waves, but watch the drift out to sea.
Wave height, next 7 daysWaves, next 7 days
Waves ease over the next few days. The biggest waves arrive on Wednesday 28: 11 ft with a period of 12 s, from the west-northwest (rough).
Water temperature
Water temperature →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.

Diving in Ferrol today
Diving and snorkeling today
Likely visibility: poor- Slack water around low tide (11:13 am): little current from 10:50 am to 11:30 am
- 9.5 ft swell at 11 s from the northwest: heavy surge on the bottom
- Almost no wind
- 0.1 mph current toward the west, weak (model)
- Sun high: more light underwater
Not a day for shore diving: swell, wind, current or storms during the best window. If you go, go with a dive shop and only if they give the OK.
- Slack water today: high tide 5:02 am (4:40–5:20 am), low tide 11:13 am (10:50–11:30 am), high tide 5:27 pm (5:10–5:50 pm) and low tide 11:30 pm (11:10–11:50 pm)
- Likely visibility: poor. Swell (up to 11 ft at 10 s) over the last few days has stirred up the water. Based on the last 24 hours of data.
- Water at 58.6 °F: a 7 mm wetsuit, with hood and booties.
- Snorkeling: better not, with these waves, wind or current.
- Night dive: dark from 6:59 pm. Waning gibbous (93%), rising at 7:44 pm: a bright night.
Your diving day at a glance
The best window, 10:20 am to 12:10 pm, combines slack water at low tide, light wind, weak current and the sun high, though with a big swell. Also worth a look from 4:50 pm to 6:10 pm, with slack water at high tide, light wind and weak current, though with a big swell.
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.

The moon in Ferrol
Moon phase and position
Today the moon is 226,461 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: high- 1:56–3:56 am Major · the moon passes overhead · high activity
- 2:28–4:28 pm Major · the moon passes underfoot · high activity
- 10:36–11:36 am Minor · moonset · medium activity
- 7:14–8:14 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
Deepens quicklyThe bottom deepens quickly: 33 ft of water 0.25 mi from shore.
From the shoreline (0.7 mi from Ferrol) out to sea, heading south.
How far from shore
- 16 ft deep1,200 ft
- 33 ft deep0.25 mi
- 66 ft deepnot within 1.3 mi
- 164 ft deepnot within 1.3 mi
For fishing, swimming and diving
- Shore fishing. Deep water close in: about 8.5 ft just 330 ft out. Good for casting from rocks, jetties or the beach itself; current and surf hit harder here.
- Swimming. The water gets deeper little by little, but a few dozen yards out you can no longer stand.
- Diving. 33 ft deep 0.25 mi from shore; 66 ft is far out (beyond 1.3 mi): for deeper dives, go by boat.
Inside bays, estuaries and harbors the bottom changes a lot from spot to spot (channels and shoals): use this only as a rough guide. There is land ahead (an island, a headland or the far shore) 1.3 mi out. The profile is turned slightly from the coast so it does not run into an island or a headland. Where the bottom comes up to the surface there are shoals, rocks or an islet next to the profile.
