- Dangerous for swimming: 6.5 ft waves every 13 s; high rip current risk
- Water at 58 °F (very cold)
Dangerous surf during beach hours. Stay out if the red flag is up, and never swim where there is no lifeguard.
Today, hour by hour
- Swimming Dangerous · 6.5 ft
6.5 ft waves every 13 s: dangerous for swimming. Stay out if the red flag is up. High rip current risk. If you're caught in a rip current, don't swim against it: swim parallel to shore and wave for help. Always follow the lifeguard's flags.

2026 extremes: the highest tide of the year is on December 26 (12.6 ft) and the lowest, on August 13 (0.6 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 102, 10.8 ft range). The smallest, on October 19 (coefficient 28, 3.6 ft).

Where this tide comes from
A Illa de Arousa has no station of its own, so we use the tide at Vigo (TICON-4), 24 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 A Illa de Arousa
Sea stateSea state: moderate
The waves you may find
- Most commonMost common2.5 ft
- Significant5.0 ft
- Highest expectedHighest9.9 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 9.9 ft. Before heading out, expect waves of up to 9.9 ft.
Wind on the coast and offshore
Offshore wind. The coast faces southwest 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: 7.3 ft with a period of 12 s, from the west-northwest (moderate).
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 is steady these days, with no sudden changes.
Water colder than normal for late October (−1.8 °F).

Diving in A Illa de Arousa today
Diving and snorkeling today
Likely visibility: poor- Slack water around low tide (10:55 am): little current from 10:40 am to 11:10 am
- 6.3 ft swell at 11 s from the west-northwest: strong surge on the bottom
- Light offshore wind (9 mph)
- 0.0 mph current toward the east, weak (model)
- Sun high: more light underwater
- Slack water today: high tide 4:43 am (4:20–5:00 am), low tide 10:55 am (10:40–11:10 am), high tide 5:08 pm (4:50–5:30 pm) and low tide 11:12 pm (10:50–11:30 pm)
- Likely visibility: poor. Swell (up to 7.3 ft at 10 s) over the last few days has stirred up the water. Based on the last 24 hours of data.
- Water at 57.6 °F: a 7 mm wetsuit, with hood and booties.
- Snorkeling: better not, with these waves, wind or current.
- Night dive: dark from 7:03 pm. Waning gibbous (93%), rising at 7:51 pm: a bright night.
Your diving day at a glance
The best window, 10:20 am to 11:50 am, combines slack water at low tide, light wind, weak current and the sun high, though with a big swell. Also worth a look from 4:30 pm to 5:50 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 A Illa de Arousa
Moon phase and position
Today the moon is 226,461 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: high- 1:59–3:59 am Major · the moon passes overhead · high activity
- 2:30–4:30 pm Major · the moon passes underfoot · high activity
- 10:35–11:35 am Minor · moonset · medium activity
- 7:21–8:21 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
Drops off fastThe bottom drops off fast: the water is 33 ft deep just 380 ft from shore.
From the shoreline (0.65 mi from A Illa de Arousa) out to sea, heading southwest.
How far from shore
- 16 ft deep240 ft
- 33 ft deep380 ft
- 66 ft deep0.25 mi
- 164 ft deepnot within 1.8 mi
For fishing, swimming and diving
- Shore fishing. Deep water close in: about 29 ft just 330 ft out. Good for casting from rocks, jetties or the beach itself; current and surf hit harder here.
- Swimming. The bottom drops quickly near the shore and you are soon out of your depth. Keep an eye on kids and weak swimmers.
- Diving. Shore diving works here: 33 ft at 380 ft and 66 ft at 0.25 mi from shore.
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) 1.8 mi out. Right by the shore the bottom may drop even faster than shown.
