Your day at a glance

The best window, 1:40 pm to 2:40 pm, combines the 1:44 pm low tide, a major period, a light onshore breeze and some swell. Also good from 7:10 pm to 8:10 pm, with the 7:16 pm high tide, moonrise, a light onshore breeze and some swell. Also worth a try from 1:10 am to 2:30 am, with the 1:32 am low tide, a major period and some swell, though with rising pressure.

  • ▲ High tide 7:16 pm 6.2 ft · coef. 85

↑ Rising The tide is rising. 22 min to high tide at 8:13 am.

Tide coefficient 91 for the 8:13 am high tide and 85 for the 7:16 pm high tide. Spring tides. The water rises and falls 6.0 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 September 28 (6.8 ft) and the lowest, on February 2 (-0.9 ft).

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

Heights above chart datum (CD), the zero of that port's 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. chart datum (CD)

Tide coefficient and range in October

The biggest tides of the month came from October 26 to 27 (coefficient 104, 6.1 ft range). The smallest, on October 19 (coefficient 24, 2.2 ft).

Sea and waves

One wave in seven is higher than the significant height, and about 3 times a day one reaches 4.2 ft. Before heading out, expect waves of up to 4.2 ft.

Wind on the coast and offshore

On the coast 7 mph N · gusts 12

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

Today’s surf at a glance

The best window, 5:00 pm to 5:45 pm, has glassy water. 6:00 am to 8:00 am also works, with light offshore 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.

Your diving day at a glance

The best window, 12:30 pm to 2:50 pm, combines slack water at low tide, light wind, weak current and the sun high. Also good from 7:30 am to 9:20 am, with slack water at high tide, 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.

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
  • 1:10–3:10 am Major · the moon passes overhead · high activity
  • 1:42–3:42 pm Major · the moon passes underfoot · high activity
  • 9:16–10:16 am Minor · moonset · medium activity
  • 7:06–8:06 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 0.3 mi from shore and 33 ft at 0.35 mi. It reaches 164 ft at 2.8 mi.

From the shoreline (0.8 mi from Shimoda) out to sea, heading east.

How far from shore

  • 16 ft deep0.3 mi
  • 33 ft deep0.35 mi
  • 66 ft deep0.6 mi
  • 164 ft deep2.8 mi

For fishing, swimming and diving

  • Shore fishing. Shallow, gradual bottom (16 ft at 0.3 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 0.6 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).

Source: NOAA ETOPO 2022 (CC0), cells of about 0.3 mi; depth below mean sea level. For reference only: not for navigation or anchoring.
