Macro-Heaven
Macro-Heaven is a dive site in Bali, Indonesia. It lies within the Gili Tangkong, Gili Nanggu, Gili Sudak Marine Recreation Park. Currents typically run at 3.2 km/h and reach 6.4 km/h on the strongest days. Water temperatures range from 28°C in August to 30°C in November. The typical daily tidal range is about 1.4 m. Species recorded in the area include Pygmy Seahorse, Left-handed Hermit Crab, Chamberlain's Nembrotha and Black-margined Nudibranch.

Conditions at Macro-Heaven through the year
Sea surface temperature at the site coordinates, averaged per month from hourly model values for 2024. The water is warmest in November at about 30 °C and coolest in August at about 28 °C, a spread of 2.2 degrees across the year.

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

Ocean current at the site runs at a typical 3.2 km/h. In the strongest tenth of the hours modelled for 2024 it reaches 6.4 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 1.4 m over a day, and by up to 2.0 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 Macro-Heaven: within 10 km of the site there is land in the directions from which 96 % of the larger waves in the area arrive, so open-sea values would overstate the swell at the site itself.
Macro-Heaven lies inside Gili Tangkong, Gili Nanggu, Gili Sudak Marine Recreation Park. Protected areas can carry their own rules on entry fees, permits, anchoring and fishing; check the current rules with a local operator before you dive.
Satellite habitat mapping places Macro-Heaven on a sheltered reef slope, 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 Macro-Heaven 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. Macro-Heaven sits with its peak current in the top tenth of all listed sites.
