El Niño Threatens Mauritius Farmers With Heat and Dry Summer 2026-27

Mauritius farmers are bracing for a tough agricultural season as the El Niño weather phenomenon intensifies heading into the 2026-27 summer. Meteorologists at the Mauritius Meteorological Services are forecasting temperatures above seasonal norms, with coastal areas in the west of the island potentially recording highs of up to 36 degrees Celsius on some days.

Rainfall is expected to reach only around 80 percent of its usual level, meaning a significant shortfall that will strain water supplies already under pressure across the island. The combination of excessive heat and below-average precipitation is set to create difficult conditions for the country's agricultural sector over the coming months.

Several vegetable crops are particularly at risk. Greenhouse tomatoes, leafy vegetables, cabbages and beans are among the most exposed, as reduced water availability can slow plant development, cut yields and add to the daily workload of smallholder farmers known locally as planteurs. These growers form the backbone of Mauritius's domestic food production and already operate on tight margins.

The heat is also expected to encourage the spread of crop pests. Thrips, a small insect that feeds on plants, could become more prevalent and cause damage to tomatoes, chillies and aubergines, three staples of local Mauritian cuisine and market trade.

In response to the anticipated challenges, the Ministry of Agro-Industry is reportedly working on a set of measures to help the sector cope. These are expected to include water rationing protocols and the possibility of postponing certain planting schedules to avoid the worst of the heat. Full details of the support plan have not yet been released.

El Niño is a naturally occurring climate cycle that warms surface waters in the central and eastern Pacific Ocean, disrupting weather patterns around the world. For island nations in the Indian Ocean such as Mauritius, a strong El Niño event typically means hotter and drier summers, with a higher risk of drought conditions.

What this means: For Mauritian consumers, a difficult growing season could lead to reduced supply of locally produced vegetables and upward pressure on market prices. Farmers with limited access to irrigation infrastructure will be among the most vulnerable. The government's response in the coming weeks will be critical in determining how well the sector can absorb the impact of what forecasters are describing as a notably harsh summer ahead.
