A High wave warning is in force in Mauritius.

The presence of Severe Tropical Storm CANDICE to the South-South-East of Mauritius is causing heavy swells our region.



As a result, the sea state is rough to very rough. Wave-height of 4 to 5 metres is being observed mainly to the Southern part of the island.

The heavy swells may break along the beaches during high tides.

Fishermen, pleasure-crafts users and the public are strongly advised not to go out at sea and even on those beaches during high tides.


Saturday 27 January 2024 : High 02h35 and 13h49
Sunday 28 January 2024 : High 02h57 and 14h19


The Mauritius Meteorological Services issues warning for high waves arising from heavy swells which has originated far from our region or due to storm tide arising from a distant storm/cyclone. As far as practicable, about 12 hours in advance, a Special Communiqué is issued to inform the public of any impending high waves based on observation available.

A Swell is an ocean wave system raised at some distance away due to winds blowing over that area and not raised by the local wind blowing at the time of observation. Swell waves travel from their source, usually out of a stormy or a fetch of windy area and continue on in the direction of the winds that originally formed them as sea waves. The swell may travel for thousands of miles before dying away. As the swell wave advances, its crest becomes flattened and rounded and its surface smooth. Swell waves are characterized by a relatively long and regular period.


At all times swells may be present in a sea but the amplitude varies from time to time. The amplitude and impacts of the swells in a particular region will depend on:

  1. The amplitude of the swells at source. High amplitude swell at source is likely to be more energetic even distances far away from its source.
  2. State of Astronomical Tide: The amplitude of any swells in a particular location will be more significant during spring tide (which occurs during full moon or new moon).
  3. Phase of Astronomical Tide:  The amplitude and impact any swell is further exacerbated by the tide phase (high or low tide). This is of particular importance in the lagoons, where during high tides, it can lead to significant bulge of water.
