Conditions at Tanjung Loh Sera 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 July at about 26 °C, a spread of 3.7 degrees across the year.

Ocean current at the site runs at a typical 0.9 km/h. In the strongest tenth of the hours modelled for 2024 it reaches 1.8 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 2.2 m over a day, and by up to 3.0 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 Tanjung Loh Sera: 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.

The seabed directly under the site coordinates sits at about 19 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.

Tanjung Loh Sera lies inside Komodo National 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.

How Tanjung Loh Sera compares
