Air Slope
Air Slope is a dive site in Lombok, Indonesia. The site has a slope. It lies within the Gili Ayer, Gili Meno, Gili Trawangan Marine Recreation Park. The sea floor at the site position lies at about 7 meters. Currents typically run at 1.8 km/h and reach 2.9 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 1.2 m. Species recorded in the area include Green Sea Turtle, Almond Ark, Ribbon Eel, Blue Dragon and Freckled Hawkfish.
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. Protected area boundary from OpenStreetMap contributors (ODbL). Species observations from iNaturalist, checked against the World Register of Marine Species.
Conditions at Air Slope 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 2.1 degrees across the year.
| Jan | Feb | Mar | Apr | May | Jun | Jul | Aug | Sep | Oct | Nov | Dec |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 29.4 | 29.4 | 29.7 | 30.1 | 29.8 | 29.0 | 28.7 | 28.2 | 28.5 | 29.2 | 30.3 | 29.9 |
Ocean current at the site runs at a typical 1.8 km/h. In the strongest tenth of the hours modelled for 2024 it reaches 2.9 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 1.2 m over a day, and by up to 1.7 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 Air Slope: within 10 km of the site there is land in the directions from which 77 % 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 7 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.
Air Slope lies inside Gili Ayer, Gili Meno, Gili Trawangan 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.
How Air Slope 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.
