Global weather patterns have shown significant variability across multiple regions. In late July and early August, Senegal faced warnings for rain showers and thunderstorms, while eastern France was placed under an orange vigilance for violent thunderstorms. By late August, meteorological conditions shifted toward extreme heat and tropical activity, including Tropical Storm Dolly in the Caribbean and heavy rain in Mauritius. In Tunisia, extreme heat has escalated into a severe humanitarian and infrastructure crisis. Following a period of high temperatures, July 2026 was recorded as the country’s second-hottest July since 1950. This heatwave triggered unannounced water outages and rotating electricity blackouts managed by the state utility STEG. The Tunisian Observatory of Water reported 608 incidents in July, including 549 unannounced water supply disruptions. A shortage of bottled water further impacted the commercial sector, compounded by a 30% to 40% surge in summer demand and production halts caused by power outages. This crisis has fueled political friction, with President Kaïs Saïed suggesting disruptions might be ‘organized acts of sabotage’, while the UGTT union accused the government of using conspiracy rhetoric to deflect from economic mismanagement.

The Tunisian Young Doctors Association estimated that between 150 and 200 people died from heatstroke or medical equipment failure during recent heatwaves. To manage a widening trade deficit, authorities have implemented market controls and plans to ‘rationalize’ imports. A World Bank report, ‘Tunisia’s Water Challenge: From Scarcity to Resilience’, warns that water shortages could reduce Tunisia’s GDP by 6.4% by 2050. The country currently has only 380 cubic meters of renewable freshwater per inhabitant annually, falling below the international absolute scarcity threshold. The report notes that without intervention, climate stress could result in the loss of at least 30% of agricultural jobs by mid-century. Concurrently, Mauritius is facing severe water security challenges.
