The Wall
The Wall is a dive site in Bali, Indonesia. The site has a wall. Currents typically run at 2 km/h and reach 3.8 km/h on the strongest days. Water temperatures range from 28°C in August to 30°C in December. The typical daily tidal range is about 1.3 m. Species recorded in the area include Dragon Seamoth, Trapania reticulata, Pygmy Seahorse, Peacock Mantis Shrimp and Diversidoris crocea.

Conditions at The Wall through the year
Sea surface temperature at the site coordinates, averaged per month from hourly model values for 2024. The water is warmest in December at about 30 °C and coolest in August at about 28 °C, a spread of 2.5 degrees across the year.

|---|---|---|---|---|---|---|---|---|---|---|---|

Ocean current at the site runs at a typical 2.0 km/h. In the strongest tenth of the hours modelled for 2024 it reaches 3.8 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 1.3 m over a day, and by up to 1.8 m on the largest days of the month. That range drives how much water is exchanged over the reef and when the current turns.
Offshore wave statistics are not shown for The Wall: within 10 km of the site there is land in the directions from which 100 % of the larger waves in the area arrive, so open-sea values would overstate the swell at the site itself.
Satellite habitat mapping places The Wall on a shoreline reef flat, over a seabed mapped as coral and algae. The classification comes from the nearest mapped reef polygon, about 11 m from the listed coordinates, so it describes the reef the site sits on rather than a single point on it.
How The Wall 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.
