October 2026 Among the Driest in 20 Years for Mauritius
Mauritius recorded just 52 mm of rain in October 2026, only 71% of the monthly average, making it one of the seven driest Octobers in two decades.
Mauritius has just endured one of its driest Octobers in twenty years, with the Mauritius Meteorological Services confirming that the island recorded only 52 millimetres of rainfall last month. That figure represents just 71 percent of the long-term average for October, placing this month among the seven driest Octobers since records began two decades ago.
The western region of the island suffered the most severe shortage, receiving a mere 8 millimetres of rain across the entire month. The west coast, which includes areas such as Flic en Flac and Black River, is typically drier than the central plateau or the east, but this October's readings were exceptionally low even by local standards.
Temperatures also climbed above seasonal norms. The meteorological stations at Vacoas, located on the central plateau and home to the main Mauritius Meteorological Services headquarters, and Plaisance, the area surrounding Sir Seewoosagur Ramgoolam International Airport in the south-east, both recorded above-average readings during the month.
The Mauritius Meteorological Services is the government body responsible for monitoring weather patterns, issuing cyclone warnings, and publishing climate data for the island. Its monthly reports are widely used by planners, farmers, and water authorities to track trends and prepare for seasonal changes.
This dry spell comes at a sensitive time for the island's water supply. Mauritius relies heavily on rainfall to replenish its network of reservoirs, which feed homes and businesses across the island. When dry months stack up, reservoir levels can fall quickly, putting pressure on the Central Water Authority to manage distribution carefully.
October sits at the transition between the dry austral winter and the wetter summer season, which typically runs from November to April. A dry October can delay the replenishment cycle that reservoirs depend on heading into the new year.
What this means: For residents, a drier and warmer October can signal tighter water availability in the short term, particularly in already water-stressed areas like the west. Farmers preparing for summer crops may face a difficult start to the growing season. Tourists visiting the island during this period would have experienced hotter and sunnier conditions than usual, which may appeal to beach visitors but adds to the broader concern about changing climate patterns in the Indian Ocean region. Authorities will be watching November rainfall closely to see whether the summer wet season arrives on schedule and helps restore reservoir levels across the island.

Frequently Asked Questions
How dry was October 2026 in Mauritius compared to normal?β
Mauritius received only 52 millimetres of rain in October 2026, which is 71 percent of the long-term monthly average. This makes it one of the seven driest Octobers recorded in the past twenty years, according to the Mauritius Meteorological Services.
Which part of Mauritius was most affected by the dry weather in October 2026?β
The western region of Mauritius was the hardest hit, recording just 8 millimetres of rainfall for the entire month. Areas along the west coast, such as Flic en Flac and Black River, are generally drier than the rest of the island but this was an exceptionally low reading even for that region.
Could the dry October 2026 affect Mauritius reservoir levels?β
Yes. Mauritius depends on seasonal rainfall to refill its reservoirs, which supply water to households and businesses island-wide. A dry October, which falls at the start of the wet season transition, can delay the replenishment that reservoirs need heading into summer. The Central Water Authority monitors levels closely during such periods.
