↓ Falling The tide is falling. 15 min to low tide at 6:14 pm.

Tide coefficient 93 for the 12:15 pm high tide. Spring tides. The water rises and falls 7.3 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 October 27 (10.5 ft) and the lowest, on February 20 (0.5 ft).

Semidiurnal: two high and two low tides a day, of similar height.

Heights above chart datum: the lowest astronomical tide (LAT), the zero of nautical charts in Europe. 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 (LAT)

Tide coefficient and range in October

The biggest tides of the month came from October 26 to 27 (coefficient 105, 9.1 ft range). The smallest, from October 19 to 20 (coefficient 25, 2.2 ft).

Where this tide comes from

B · Nearby station

Kathu has no station of its own, so we use the tide at Ko Taphao Noi (TICON-4), 8.6 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.

Sea and waves

Slight Douglas 3 · light breeze, Beaufort 2
Waves 3.6 ft · 5.7 s from the west-southwest (252°)
Swell 3.2 ft · 5.0 s from the west

The waves you may find

  • Most commonMost common1.8 ft
  • Significant3.6 ft
  • Highest expectedHighest7.4 ft

One wave in seven is higher than the significant height, and about 3 times a day one reaches 7.4 ft. Before heading out, expect waves of up to 7.4 ft.

Wind on the coast and offshore

On the coast 4 mph S · gusts 9

The model doesn't separate offshore wind here: it's the same as on the coast.

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.

Today’s surf at a glance

The best window, 2:00 pm to 6:00 pm, has a good size and glassy water, though with a short-period swell. 7:00 am to 9:00 am can also work, with light offshore wind, 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, 10:50 am to 1:10 pm, combines slack water at high tide, light wind and the sun high, though with some swell and current. Also worth a look from 6:10 am to 6:50 am, with slack water at low tide and light wind, though with current. Also worth a look from 5:30 pm to 6:10 pm, with slack water at low tide and light wind, 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
  • 1:34–3:34 am Major · the moon passes overhead · high activity
  • 2:07–4:07 pm Major · the moon passes underfoot · high activity
  • 8:37–9:37 am Minor · moonset · medium activity
  • 8:36–9:36 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.
