Seraya Kecil Island
Seraya Kecil Island is a dive site in Komodo, Indonesia. Currents typically run at 0.4 km/h and reach 0.9 km/h on the strongest days. Water temperatures range from 28°C in February to 30°C in November. The typical daily tidal range is about 1.4 m. Species recorded in the area include Mushroom Coral Reticulida, Peppered Moray, Blackpatch Triggerfish, Blue Demoiselle and Anchor Tuskfish.

Ocean current at the site runs at a typical 0.4 km/h. In the strongest tenth of the hours modelled for 2024 it reaches 0.9 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 1.4 m over a day, and by up to 1.8 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 Seraya Kecil Island, the highest wave of the day exceeded 1.5 m on 0.8 % of days between 2015 and 2024. The roughest month was January (5 % of days), the calmest April (0 %). Land within 10 km blocks some of the directions these waves come from (open to about 29 % of them), so conditions at the site are likely calmer than these open-sea values.
