Your day at a glance

The best window, 1:40 am to 3:10 am, combines the 2:44 am high tide, a major period, a light onshore breeze and some swell, though with rising pressure. Also good from 9:40 am to 11:30 am, with the 10:41 am low tide, moonset and some swell. Also good from 6:00 am to 7:00 am, with sunrise, a light onshore breeze and some swell.

Today's high and low tides

  • ▲ High tide 2:44 am 1.4 ft · coef. 93

↓ Falling The tide is falling. 40 min to low tide at 10:41 am.

Tide coefficient 93 for the 2:44 am high tide. Spring tides. The water rises and falls 1.2 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 August 12 (1.8 ft) and the lowest, on March 22 (-0.5 ft).

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

Heights above NLLW. Astronomical prediction: wind and air pressure can raise or lower the water by a few inches, and more in a storm. Not for navigation. NLLW

Tide coefficient and range in October

The biggest tides of the month came from October 26 to 28 (coefficient 99, 1.1 ft range). The smallest, from October 18 to 19 (coefficient 24, 0.6 ft).

Where this tide comes from

B · Nearby station

Ama has no station of its own, so we use the tide at Saigo (TICON-4), 15 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 Ama

7-day waves

Sea stateSea state: slight

Slight Douglas 3 · moderate breeze, Beaufort 4
Waves 2.5 ft · 5.7 s from the north-northwest (345°)
Swell 2.2 ft · 5.3 s from the north
Current 0.7 mph toward the NE

The waves you may find

  • Most commonMost common1.2 ft
  • Significant2.5 ft
  • Highest expectedHighest5.2 ft

One wave in seven is higher than the significant height, and about 3 times a day one reaches 5.2 ft. Before heading out, expect waves of up to 5.2 ft.

Wind on the coast and offshore

On the coast 10 mph SSW · gusts 21
Offshore (8.2 mi SW)Offshore 12 mph SSW · gusts 18

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

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 (+4.2 °F).

Today’s surf at a glance

The best window is 6:01 am to 10:00 am, though with small waves and 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, 10:00 am to 11:20 am, combines slack water at low tide, light wind and the sun high, though with 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
  • 1:09–3:09 am Major · the moon passes overhead · high activity
  • 1:41–3:41 pm Major · the moon passes underfoot · high activity
  • 9:27–10:27 am Minor · moonset · medium activity
  • 6:54–7:54 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.
