Diving Conditions
Water Temperature
At Richelieu Rock, the water temperature remains relatively stable throughout the year, typically ranging between 27°C to 30°C. These warm waters provide a comfortable diving experience which is suitable for most divers. However, mild seasonal fluctuations can be noticed, with slightly cooler temperatures occurring between December and February when the water can drop to around 27°C.

Visibility
Visibility at Richelieu Rock can vary significantly depending on the season. During the peak season, typically from February to April, divers can expect visibility ranging from 20 to 30 meters, providing clear views of the vibrant marine life and coral formations. The monsoon season from May to October often reduces visibility, sometimes dropping it to below 10 meters due to increased plankton and sediment in the water. The transition periods in November and December can see fluctuating conditions, but generally, visibility improves as the months progress.
Currents and Tides
The currents around Richelieu Rock can be quite strong and change with the tidal cycles. Generally, the best diving conditions occur during slack tides when there is minimal water movement, providing calmer waters. The currents tend to be stronger during the monsoon season from May to October, which can make diving more challenging for less experienced divers. During the peak season, currents are milder, making it easier to explore the underwater scenery. It’s recommended to plan dives around the tide schedules to ensure the most favorable conditions.
Recap
In conclusion, diving at Richelieu Rock offers unique and rewarding experiences throughout the year, but the best times to dive here are during the peak months of February to April. During these months, divers can enjoy excellent visibility, warm water temperatures, and an abundance of spectacular marine life. While off-peak seasons may present challenges, such as lower visibility and the potential for adverse weather, they also offer quieter dive sites and unique encounters with different marine species.
