Anemone Reef
Anemone Reef is a dive site in Phuket, Thailand. The sea floor at the site position lies at about 29 meters. Currents typically run at 0.6 km/h and reach 1.3 km/h on the strongest days. Water temperatures range from 29°C in January to 31°C in May. The typical daily tidal range is about 1.8 m. Species recorded in the area include Painted Scallop, Indo-Pacific Sergeant Major, Almond Ark, Doublebar Rabbitfish and Rainbow Monocle Bream.
Dive Conditions
Data sources: currents and water temperature from Open-Meteo Marine (CC BY 4.0), hourly model values 2024; seabed depth from the GEBCO 2020 Grid, sampled at the site coordinates (grid resolution about 450 m). Tidal range is the median daily range of modelled sea level from Open-Meteo Marine, hourly values 2024. Species observations from iNaturalist, checked against the World Register of Marine Species.
Conditions at Anemone Reef through the year
Sea surface temperature at the site coordinates, averaged per month from hourly model values for 2024. The water is warmest in May at about 31 °C and coolest in January at about 29 °C, a spread of 2.6 degrees across the year.
| Jan | Feb | Mar | Apr | May | Jun | Jul | Aug | Sep | Oct | Nov | Dec |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 28.8 | 29.1 | 29.7 | 30.7 | 31.4 | 30.5 | 30.1 | 30.1 | 29.5 | 29.9 | 29.9 | 29.2 |
Ocean current at the site runs at a typical 0.6 km/h. In the strongest tenth of the hours modelled for 2024 it reaches 1.3 km/h, which is when entries are normally timed to slack water at the turn of the tide.
The tide moves the water level by a median 1.8 m over a day, and by up to 2.5 m on the largest days of the month. That range drives how much water is exchanged over the reef and when the current turns.
In the open sea off Anemone Reef, the highest wave of the day exceeded 1.5 m on 0.0 % of days between 2015 and 2024. In no month did this happen on more than 1 % of days.
The seabed directly under the site coordinates sits at about 29 m. This is a bathymetry grid value with a cell size of roughly 450 m, so it describes the depth of the area rather than the deepest point a dive can reach.
How Anemone Reef compares
These comparisons use only the measured values above, set against the 376 dive sites published on findadive.com. A percentage shows the share of other sites with a lower (or higher) value, so it reads the same way wherever the site is.
