Mauritius Reservoirs at 49.6% as Weekend Rain Brings Hope
Showers forecast for eastern Mauritius and the Central Plateau on Saturday may help ease a worrying drop in the island's water reserves.
Mauritius is set to receive a welcome bout of rainfall this Saturday, with meteorologists warning of cloudy skies and moderate showers that could offer some relief to the island's depleted water reservoirs.
According to a bulletin issued at 4:30 a.m. on Saturday 7 November by the Mauritius Meteorological Services, clouds moving in from the east are currently influencing local weather conditions. The sky will remain largely overcast, with showers, sometimes moderate, expected mainly in the east of the island and over the Central Plateau, the elevated inland region that sits at the heart of the island's water catchment system. Patches of fog are also possible in some areas.
Temperatures will be relatively mild, ranging between 25 and 27 degrees Celsius on the Central Plateau and between 29 and 32 degrees on coastal areas. Winds will blow from the east at around 25 km/h, with gusts reaching up to 50 km/h.
The rain comes at a critical moment for the island's water supply. According to the most recent figures available, dated 5 November, the combined fill level across Mauritius's seven main reservoirs stood at just 49.6 percent, roughly half their total capacity. The situation is particularly acute at Mare-aux-Vacoas, the country's largest reservoir located in the Plaines Wilhems district of the Central Plateau. That reservoir was at only 32.8 percent of capacity, a level that raises serious concerns for household and agricultural water supply.
Mare-aux-Vacoas is managed by the Central Water Authority (CWA), the state body responsible for water production and distribution across the island. It is the primary source of drinking water for a large part of the population, making its fill level a closely watched indicator of water security.
For Saturday's showers to make a meaningful difference, rainfall would need to reach the catchment basins, the natural drainage areas surrounding the reservoirs where rainwater collects and flows into the water supply system. The Central Plateau, where much of this weekend's rain is expected to fall, is precisely the area where several of these catchment zones are located, making the forecast more promising than coastal rain alone would be.
What this means: If you live in Mauritius, particularly in areas served by Mare-aux-Vacoas, the current reservoir situation is a reminder that water restrictions or pressure reductions remain a real possibility if rainfall stays below seasonal norms. This weekend's showers are encouraging but are unlikely on their own to fully reverse weeks of below-average precipitation. Residents and businesses should continue using water efficiently while authorities monitor levels in the coming days.

Frequently Asked Questions
How full are Mauritius's reservoirs right now?β
As of 5 November 2025, the seven main reservoirs in Mauritius had a combined fill level of 49.6 percent. Mare-aux-Vacoas, the largest reservoir managed by the Central Water Authority and located in the Plaines Wilhems district, was at only 32.8 percent of its capacity.
Where is rain expected in Mauritius this Saturday?β
The Mauritius Meteorological Services forecast showers, sometimes moderate, mainly in the east of the island and over the Central Plateau on Saturday 7 November. Fog patches are also possible in some areas, with winds gusting up to 50 km/h.
Will this weekend's rain improve Mauritius's water supply?β
It could help, but only if rainfall reaches the catchment basins that feed the reservoirs. The Central Plateau, where much of the rain is forecast, is home to several of these catchment zones. However, one weekend of showers is unlikely to fully reverse the current shortage on its own.
