Mauritius Sea Temperatures

The temperature of the Indian Ocean in the region of Mauritius is higher during the summer, and in winter time the temperature of the water will drop a little.

Sea temperatures are generally pleasant throughout the year ranging from 26-29° C in summer to 23-25° C in winter. Strong anticyclones in winter may occasionally cause the sea temperature to fall by 2 or 3° C.

The sea temperatures peak in the range 28 to 29°C during the beginning of February and are at their lowest on during August, in the range 23 to 24°C (72 to 75°F).

Mauritius’ excellent sea conditions are the result of the coral reef surrounding the entire island. Accordingly Mauritius benefits calm lagoon water along its coastlines. Also the beautiful coral reefs make it a perfect place to learn to dive and to enjoy wide range of water sport activities.

Actual sea surface water temperatures close to shore can vary by several degrees compared with these open water averages. This is especially true after heavy rain, close to river mouths or after long periods of strong offshore winds. Offshore winds cause colder deep water to replace surface water that has been warmed by the sun. Air temperature, wind-chill and sunshine should also be considered before deciding on the kind of wetsuit needed to stay warm when surfing at Port Louis. Refer to our detailed weather forecasts for this information.

The lagoons inside the barrier reefs are shallow and ideal for bathing, swimming and for range of water sport activities.

Below is a graph of Historical Sea Surface Temperature Mauritius, focusing mainly on the west coast and the region of Port Louis. This has been derived from analysis of two decades of oceanographic satellite measurements of nearby open water.

Accordingly, it is possible to calculate the average water temperature variation around the year as well as the extremes that have been observed on each date.
