Where this tide comes from
Comillas has no station of its own, so we use the tide at Santander (TICON-4), 26 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.

Sea stateSea state: moderate
The waves you may find
- Most commonMost common3.4 ft
- Significant6.8 ft
- Highest expectedHighest13 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 13 ft. Before heading out, expect waves of up to 13 ft.
Wind on the coast and offshore
Offshore wind. The coast faces north and the wind blows from land out to sea: calm shore and clean waves, but watch the drift out to sea.

Waves stay much the same all week. The biggest waves arrive on Wednesday 28: 6.9 ft with a period of 11 s, from the northwest (moderate).

Surf in Comillas today
Surf today
Good- 4.8–7.3 ft surf at the shore, a good size with some punch
- Big surf (7.3 ft): for experienced surfers
- 6.5 ft swell at 10 s from the northwest, a bit short
- Light offshore wind (5 mph): it holds up and grooms the waves
- First or last light of the day
- Falling tide (low tide at 11:31 am)
Big surf: for experienced surfers only. If in doubt, stay on the beach.
- Light: First light 7:18 am · sunrise 7:47 am · sunset 6:14 pm · last light 6:44 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 63.0 °F: a 3/2 fullsuit.
- Energy: 724 kJ · High power
Today’s surf at a glance
The best window, 7:18 am to 11:00 am, has a good size and light offshore wind, though with big surf. 6:00 pm to 6:44 pm can also work, with a good size, though with big surf and cross-shore wind.
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.
Diving in Comillas today
Diving and snorkeling today
Likely visibility: poor- Slack water around low tide (11:31 am): little current from 11:10 am to 11:50 am
- 6.2 ft swell at 11 s from the northwest: strong surge on the bottom
- Moderate cross-shore wind (16 mph)
- 0.3 mph current toward the west, weak (model)
- Sun high: more light underwater
- Slack water today: high tide 5:19 am (5:00–5:40 am), low tide 11:31 am (11:10–11:50 am), high tide 5:45 pm (5:20–6:10 pm) and low tide 11:48 pm (11:30 pm–12:10 am)
- Likely visibility: poor. Swell (up to 7.5 ft at 10 s) over the last few days has stirred up the water. Based on the last 24 hours of data.
- Water at 63.0 °F: a 7 mm wetsuit, with hood and booties.
- Snorkeling: better not, with these waves, wind or current.
- Night dive: dark from 6:44 pm. Waning gibbous (93%), rising at 7:29 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, weak current and the sun high, though with a big swell and moderate wind. 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- 1:40–3:40 am Major · the moon passes overhead · high activity
- 2:11–4:11 pm Major · the moon passes underfoot · high activity
- 10:19–11:19 am Minor · moonset · medium activity
- 6:59–7:59 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.

For fishing, swimming and diving
- Shore fishing. About 11 ft of water 330 ft out: long casts help, and so does a rising tide, which brings fish closer in.
- 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 0.45 mi and 66 ft at 0.7 mi from shore.
