The verdict

A good dive, worth a day.

A cluster of submerged granite pinnacles in open water northwest of Koh Tao, reached by boat, with tops at about 12 m and walls dropping to around 45 m. The upper rock is carpeted in anemones with pink anemonefish, and soft corals and sea fans grow on the deeper faces.

Schools of barracuda, trevally and batfish circle the pinnacles, giant groupers shelter among the rocks, and whale sharks pass through in season. Currents can be strong, so the site suits advanced divers with good buoyancy who keep a close eye on depth and no-decompression time.

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 Chumpon Pinnacle.

8.6Big draws. A shark, ray, turtle or other big draw on about 8 dives in 10 in the best months, most often pickhandle barracuda, striped seapike and herring scad.
6.3Reef 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".

113 species likely at Chumpon Pinnacle: 40 recorded here, 73 at similar sites nearby, from divers' logs, GBIF and iNaturalist. iNaturalist observations by their observers, CC BY SA 4.0.See them by month

How we grade

One number, built from dives people actually logged.

Never paid for. Dive centers can reply, not change a score.
  • 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.
  • Graded as a pinnacleChumpon Pinnacle is a deep, exposed offshore site, dived for the structure and the life it draws more than for coral. Marine life counts for 45% of the score here and the reef 10%.
  • 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 8.3 °C-weeks of heat stress, when coral bleaching is likely), −0.9.
  • Hard isn't worseCurrent and depth are shown on their own. A tough site can still score 10.
