The verdict
A good dive, worth a day.
Lighthouse Pinnacle, known locally as Leam Fai Wap, is a reef wall lying off Koh Tao's northeast coast beneath the island's old lighthouse. Reached by boat, the dive runs from about 5 m at the top down to 18 m, so it works for beginner-certified divers as well as those wanting a relaxed wall profile.
Green and hawksbill turtles have been recorded in the area, along with moon wrasse, tattooed parrotfish and nudibranchs such as Tryon's hypselodoris. It is often visited as a second dive of the day.

How is this measured?
Mostly from years of satellite readings of how clear the water is around this site. Each bar runs from a bad day, which about 1 day in 10 is worse than, to a great day, which about 1 day in 10 beats; the line marks a typical day. Satellites can't see through cloud, so stormy days are underrepresented and the real bad days can be murkier. For 12 months here, local dive centers report worse days than the satellites see, so the bar starts at their figure. Logged dives will sharpen it over time.
Chance of seeing it on a dive, by monthThe big draws first, then the most frequent. Share of sampled dive days that recorded the species. Months with few dives on record lean on the months around them and the rest of the year, and are shown lighter. A dash means under 1 %.

Marine life
What you'll see at Lighthouse Pinnacle.
2.1Big draws. A shark, ray, turtle or other big draw on about 1 dive in 10 in the best months, most often ribbontailed stingray.
5.9Reef life. Variety: how many different species a few dives here turn up, compared with other sites.
The big draws first (sharks, rays, turtles, octopus and the like) when they turn up on at least 1 dive in 20 in their best month, then the regulars, ranked by how often divers record them across the year. Each percentage is the share of sampled dive days that recorded the species. Where this site has few records of its own, sightings from similar nearby sites (same side of the island, similar depth and exposure) are added at a lower weight and marked "seen nearby".

How we grade
One number, built from dives people actually logged.
- Big draws or varietyMarine life scores the better of two things: how often sharks, rays, turtles and other big draws turn up, and how varied the reef life is, plus a little for having both. Both are per dive, so busy sites can't win on volume.
- By monthEvery month has its own score. Pick a month to see yours.
- Thin data, cautious scoreFew dives or reviews? The score leans toward the regional average.
- Reef healthThe reef score counts coral variety, and recent marine heatwaves that bleach coral take up to 3 points off it, fading over the years after as the reef recovers. Here: the 2024 marine heatwave (peak 7.9 °C-weeks of heat stress), −0.8.
- Hard isn't worseCurrent and depth are shown on their own. A tough site can still score 10.
