Tide coefficient 98 for the 12:16 pm high tide. Spring tides. The water rises and falls 8.6 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?

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

Where this tide comes from

M · Global model

Ko Lanta Yai has no tide station nearby: its tide is calculated with the global FES2022 model, from the nearest model cells offshore (the first one 0.9 mi away). It may differ from the real tide by a few minutes and inches, and more with wind or storms. Heights are above mean sea level, not chart datum, so low tides are negative. Not for navigation.

Model attribution: FES2022 Tide was produced by LEGOS, NOVELTIS and CLS, funded by CNES, and distributed by AVISO (https://doi.org/10.24400/527896/a01-2024.004), AVISO licence (https://www.aviso.altimetry.fr/fileadmin/documents/data/License_Aviso.pdf). Modified by TidePlanet: constants interpolated from the nearest model cells offshore; heights above mean sea level.

Sea and waves

One wave in seven is higher than the significant height, and about 3 times a day one reaches 4.1 ft. Before heading out, expect waves of up to 4.1 ft.

Wind on the coast and offshore

On the coast 7 mph ESE · gusts 15
Offshore (6.4 mi WSW)Offshore 13 mph SW · gusts 18

Cross-offshore wind. The coast faces southwest and the wind comes off the land at an angle: calmer water near the shore, and bait and boats drift out to sea.

Today’s surf at a glance

The best window, 9:00 am to 1:00 pm, has light offshore wind, though with a short-period swell and wind swell. 4:00 pm to 6:00 pm can also work, though with a short-period swell. 6:00 am to 8:00 am can also work, with light offshore wind, though with small waves, a short-period swell, wind swell and thunderstorms.

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, 11:30 am to 1:10 pm, combines slack water at high tide, light wind, weak current and the sun high. Also good from 5:20 pm to 6:00 pm, with 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
  • 1:31–3:31 am Major · the moon passes overhead · high activity

  • 8:33–9:33 am Minor · moonset · medium activity
  • 8:34–9:34 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 0.55 mi from shore and 33 ft at 0.75 mi.

From the shoreline (2.2 mi from Ko Lanta Yai) out to sea, heading southwest.

How far from shore

  • 16 ft deep0.55 mi
  • 33 ft deep0.75 mi
  • 66 ft deep1.7 mi
  • 164 ft deepnot within 3.1 mi

For fishing, swimming and diving

  • Shore fishing. Shallow, gradual bottom (16 ft at 0.55 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. Shallow near shore: you only reach 33 ft at 0.75 mi. For dives deeper than 33 ft, go by boat.

Rough estimate: here the data comes in cells of about 0.3 mi and misses details near shore (rocks, sandbars, small coves).
