Where this tide comes from
Playa Las Docas has no station of its own, so we use the tide at Valparaíso (TICON-4), 8.5 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 Playa Las Docas
Sea stateSea state: moderate
The waves you may find
- Most commonMost common2.9 ft
- Significant5.7 ft
- Highest expectedHighest11 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 11 ft. Before heading out, expect waves of up to 11 ft.
Wind on the coast and offshore
Cross-onshore wind. The coast faces west and the wind comes in from the sea at an angle: a bit more surf at the shore and drift along the coast, toward land.
Wave height, next 7 daysWaves, next 7 days
Waves build over the next few days. The biggest waves arrive on Monday 2: 8.3 ft with a period of 13 s, from the southwest (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.
Water warmer than normal for late October (+7.6 °F).

Surf in Playa Las Docas today
Surf today
Good- 3.1–4.7 ft surf at the shore, a good size with some punch
- 3.9 ft swell at 9 s from the southwest, a bit short
- Almost no wind (3 mph): glassy water
- First or last light of the day
- Rising tide (high tide at 12:49 am)
- Light: First light 6:25 am · sunrise 6:51 am · sunset 8:10 pm · last light 8:36 pm
- Tide: high 12:04 am (4.6 ft), low 6:40 am (-0.3 ft), high 12:27 pm (3.0 ft) and low 6:12 pm (-0.1 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 60.8 °F–63.9 °F: a 4/3 fullsuit.
- Energy: 216 kJ · Medium power
Today’s surf at a glance
The best window, 8:00 pm to 8:36 pm, has a good size and glassy water. 9:00 am to 12:00 pm can also work, with a good size and glassy water, though with a short-period swell.
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.

Your diving day at a glance
The best window, 11:30 am to 1:30 pm, combines slack water at high tide, light wind, weak current and the sun high, though with some swell. Also worth a look from 5:30 pm to 6:50 pm, with slack water at low tide, light wind and weak current, though with some 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.

Moon phase and position
Today the moon is 226,432 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: high- 2:21–4:21 am Major · the moon passes overhead · high activity
- 2:53–4:53 pm Major · the moon passes underfoot · high activity
- 7:47–8:47 am Minor · moonset · medium activity
- 11:02 pm–12:02 am 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. Shallow, gradual bottom (16 ft at 0.45 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. Shore diving works here: 33 ft at 0.55 mi and 66 ft at 0.65 mi from shore.
Rough estimate: here the data comes in cells of about 0.3 mi and misses details near shore (rocks, sandbars, small coves).
