Gili Mimpang
Gili Mimpang is a dive site in Bali, Indonesia. The sea floor at the site position lies at about 22 meters. Currents typically run at 3.6 km/h and reach 5.7 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 1.4 m. Species recorded in the area include Snowflake Moray, Hawksbill Sea Turtle, Whitespotted Frillgoby, Freckled Goatfish and Convict Surgeonfish.
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 Gili Mimpang 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 degrees across the year.

Ocean current at the site runs at a typical 3.6 km/h. In the strongest tenth of the hours modelled for 2024 it reaches 5.7 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 1.9 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 Gili Mimpang, the highest wave of the day exceeded 1.5 m on 3.7 % of days between 2015 and 2024. The roughest month was July (10 % of days), the calmest November (0 %).

The seabed directly under the site coordinates sits at about 22 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.
Satellite habitat mapping places Gili Mimpang on an outer reef slope, over a seabed mapped as coral and algae.
How Gili Mimpang compares
These comparisons use only the measured values above, set against the 376 dive sites published on findadive.com.
