Today's high and low tides

  • ▲ High tide 2:43 am 4.3 ft · coef. 84
  • ▼ Low tide 8:41 am 2.3 ft
  • ▲ High tide 1:25 pm 5.9 ft · coef. 81

↓ Falling The tide is falling. 4 h 58 min to low tide at 9:52 pm.

Tide coefficient 84 for the 2:43 am high tide and 81 for the 1:25 pm high tide. Average coefficient. The water rises and falls 6.8 ft between the highest high and the lowest low: a large range for this place. 70 is an average tide here; 90 and above means spring tides; below 45, neap tides. What is the tide coefficient?

2026 extremes: the highest tide of the year is on December 24 (6.4 ft) and the lowest, on June 16 (-1.6 ft).

Mixed: two high and two low tides a day, but of quite different heights.

Heights above mean lower low water (MLLW), the zero of US nautical charts. Astronomical prediction: wind and air pressure can raise or lower the water by a few inches, and more in a storm. Not for navigation. MLLW

Tide coefficient and range in October

The biggest tides of the month came from October 8 to 10 (coefficient 89, 5.3 ft range). The smallest, from October 17 to 18 (coefficient 40, 4.0 ft).

Where this tide comes from

A · Official station

Tides from the Reynolds station (NOAA), 0.3 mi from Marconi. Times and heights are its predictions. It is a NOAA subordinate station: its times and heights come from the San Francisco (Golden Gate) reference station with the official corrections.

Sea and waves

The sea at Marconi

7-day waves

Moderate Douglas 4 · moderate breeze, Beaufort 4
Waves 5.6 ft · 8.6 s from the west-northwest (299°)

The waves you may find

  • Most commonMost common2.8 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.

Cross-shore wind. The coast faces southwest and the wind blows along the shore: drift and current run parallel to the beach.

Your diving day at a glance

The best window, 12:40 pm to 3:00 pm, combines slack water at high tide, light wind, weak current and the sun high, though with some swell. Also worth a look from 7:30 am to 9:20 am, 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.

Never dive alone and check with the local dive shop: this rating is a guide, not a substitute for a professional.

Solunar periods

Today's activity: medium
  • 1:55–3:55 am Major · the moon passes overhead · high activity
  • 2:27–4:27 pm Major · the moon passes underfoot · high activity
  • 10:17–11:17 am Minor · moonset · medium activity
  • 7:33–8:33 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

Shallow, gradual

Shallow, gradual bottom: 16 ft at 160 ft from shore and 0.3 ft at 1 mi. Right off the beach it already drops to about 18 ft.

From the shoreline out to sea, heading southwest.

How far from shore

  • 16 ft deep160 ft
  • 33 ft deepnot within 1 mi
  • 66 ft deepnot within 1 mi
  • 164 ft deepnot within 1 mi

For fishing, swimming and diving

  • Shore fishing. Deep water close in: about 18 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. Shallow: the water doesn't reach 33 ft within 1 mi. For deeper dives, take a boat farther out.

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 mi out. Right by the shore the bottom may drop even faster than shown.
