Where this tide comes from
Castro-Urdiales has no station of its own, so we use the tide at Santander (TICON-4), 29 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 Castro-Urdiales
Sea stateSea state: moderate
The waves you may find
- Most commonMost common3.0 ft
- Significant6.0 ft
- Highest expectedHighest12 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-offshore wind. The coast faces north and the wind comes off the land at an angle: calmer water near the shore, and bait and boats drift out to sea.
Wave height, next 7 daysWaves, next 7 days
Waves stay much the same all week. The biggest waves arrive on Wednesday 28: 6.0 ft with a period of 11 s, from the northwest (moderate).
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.
Water warmer than normal for late October (+1.7 °F).

Surf in Castro-Urdiales today
Surf today
Good- 4.1–6.3 ft surf at the shore, a good size with some punch
- 5.6 ft swell at 10 s from the northwest, a bit short
- Light offshore wind (6 mph): it holds up and grooms the waves
- First or last light of the day
- Falling tide (low tide at 11:31 am)
- Light: First light 7:13 am · sunrise 7:43 am · sunset 6:10 pm · last light 6:39 pm
- Tide: high 5:19 am (14.3 ft), low 11:31 am (1.7 ft), high 5:45 pm (14.1 ft) and low 11:48 pm (2.2 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 64.4 °F: a 3/2 fullsuit.
- Energy: 524 kJ · High power
Today’s surf at a glance
The best window, 7:13 am to 10:00 am, has a good size and light offshore wind. 12:00 pm to 1:00 pm also works, with a good size.
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.

- Snorkeling: better not, with these waves, wind or current.
- Night dive: dark from 6:39 pm. Waning gibbous (93%), rising at 7:24 pm: a bright night.
Your diving day at a glance
The best window, 10:40 am to 12:20 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 5:30 pm to 6:10 pm, with slack water at high tide and weak current, though with a big 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.

Moon phase and position
Today the moon is 226,461 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: high- 1:35–3:35 am Major · the moon passes overhead · high activity
- 2:07–4:07 pm Major · the moon passes underfoot · high activity
- 10:15–11:15 am Minor · moonset · medium activity
- 6:54–7:54 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 180 ft from shore. It reaches 164 ft at 1.9 mi.
From the shoreline (0.25 mi from Castro-Urdiales) out to sea, heading north.
How far from shore
- 16 ft deep90 ft
- 33 ft deep180 ft
- 66 ft deep0.7 mi
- 164 ft deep1.9 mi
For fishing, swimming and diving
- Shore fishing. Deep water close in: about 41 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 180 ft and 66 ft at 0.7 mi from shore.
Right by the shore the bottom may drop even faster than shown.
