Ocean current at the site runs at a typical 1.7 km/h. In the strongest tenth of the hours modelled for 2024 it reaches 3.2 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.
In the open sea off Marlin Hill, the highest wave of the day exceeded 1.5 m on 2.0 % of days between 2015 and 2024. The roughest month was July (5 % of days), the calmest April (0 %).
