Where this tide comes from

B · Nearby station

San Marco has no station of its own, so we use the tide at Palinuro (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.

How we calculate the tide

Sea and waves

The sea at San Marco

7-day waves

Sea stateSea state: smooth

Smooth Douglas 2 · moderate breeze, Beaufort 4
Waves 0.9 ft · 3.9 s from the west-northwest (293°)
Swell 0.5 ft · 3.7 s from the west-southwest

The waves you may find

  • Most commonMost common0.4 ft
  • Significant0.9 ft
  • Highest expectedHighest1.8 ft

One wave in seven is higher than the significant height, and about 3 times a day one reaches 1.8 ft. Before heading out, expect waves of up to 1.8 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.

Today’s surf at a glance

The best window, 6:00 am to 10:00 am, has light offshore wind, though with barely any waves.

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, 9:30 am to 11:00 am, combines slack water at high tide, little swell, light wind, weak current and the sun high. Also good from 3:20 pm to 4:50 pm, with slack water at low tide, little swell, light wind and weak current.

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.

Solunar periods

Today's activity: high
  • 12:19–2:19 am Major · the moon passes overhead · high activity
  • 12:51–2:51 pm Major · the moon passes underfoot · high activity
  • 8:46–9:46 am Minor · moonset · medium activity
  • 5:52–6:52 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

Gentle slope

The bottom slopes gently: 16 ft deep 0.35 mi from shore and 33 ft at 0.35 mi. It reaches 164 ft at 2.9 mi.

From the shoreline (2.1 mi from San Marco) out to sea, heading southwest.

How far from shore

  • 16 ft deep0.35 mi
  • 33 ft deep0.35 mi
  • 66 ft deep0.75 mi
  • 164 ft deep2.9 mi

For fishing, swimming and diving

  • Shore fishing. Shallow, gradual bottom (16 ft at 0.35 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 0.35 mi and 66 ft at 0.75 mi from shore.
