Morocco's Historic Winter 2025-2026: From Drought to Record Floods
Morocco entered the winter of 2025-2026 as a country in crisis. Years of devastating drought had emptied reservoirs, decimated harvests, and pushed water rationing into major cities. The national conversation was about scarcity: dwindling aquifers, dying crops, and the specter of a permanently drier future. Then the rains came. And they did not stop.
The winter of 2025-2026 will be recorded in Morocco's meteorological history as one of the most extraordinary seasons on record. From late November through March, a relentless succession of Atlantic depressions battered the country, delivering rainfall totals that shattered long-standing records in multiple regions. What began as relief from drought became, in many areas, a different kind of emergency: catastrophic flooding, infrastructure destruction, and loss of life. This is the story of a winter that rewrote Morocco's weather records and challenged everything the country thought it knew about its own climate.
The Setup: Years of Drought
To understand the significance of winter 2025-2026, it is necessary to understand what preceded it.
The 2020-2024 Drought
Morocco experienced one of its most severe multi-year droughts from 2020 through much of 2024. The numbers were stark.
- National dam fill rates dropped below 25% by autumn 2024, the lowest level in decades.
- Cereal production collapsed, with the 2023-2024 harvest yielding less than 3.5 million tonnes against a target of 10 million.
- Groundwater levels in key aquifers, particularly the Souss-Massa, Haouz, and Saiss, continued their multi-decade decline, with some monitoring wells showing drops of 2 to 3 meters per year.
- Water rationing was implemented in several cities, including parts of Marrakech, Taroudant, and communities in the Draa-Tafilalet region.
- Rural displacement accelerated as rain-fed farming became unviable in the most affected regions.
The drought was not merely a weather event. It was a systemic crisis that exposed the fragility of Morocco's water infrastructure and agricultural model. By October 2025, the country was desperate for rain.
November 2025: The Season Opens
The first significant rains arrived in late November 2025, roughly on schedule for the start of the wet season. But the character of these early storms was unusual.
Atlantic Depressions Line Up
A persistent pattern established itself in the upper atmosphere: a deep trough over the eastern Atlantic, extending south toward the Canary Islands, steered a succession of Atlantic depressions directly into Morocco. This pattern, known in meteorology as a "blocked omega," kept the storm track aimed at northwest Africa for weeks at a time, with only brief dry interludes.
Early Totals
By the end of November, several stations had already recorded 150 to 200% of their average November rainfall. The Rif and Tangier region were particularly affected, with some stations exceeding their entire November average in the first two weeks.
The initial reaction was relief. Dam levels began to rise for the first time in months. Farmers planted winter cereals in newly moistened soil. The national mood, if not celebratory, was cautiously optimistic.
December 2025: The Deluge Begins
December changed the narrative from relief to alarm. The Atlantic depression train intensified, and Morocco experienced rainfall of historic proportions.
Tangier: Unprecedented Rainfall
Tangier, already one of Morocco's wettest cities, recorded extraordinary precipitation in December 2025.
- Monthly total: Over 350 mm, roughly three times the December average.
- Peak intensity: One 48-hour period delivered over 120 mm, overwhelming the city's drainage infrastructure.
- Flooding: Low-lying neighborhoods experienced significant flooding. The Tangier medina, built on steep terrain, channeled water down its narrow streets like a network of rivers.
The Safi Catastrophe
The most devastating event of December 2025 occurred in the Safi region, where a stalled Atlantic depression delivered exceptional rainfall to the Abda-Doukkala plain.
- Rainfall totals: Some stations recorded over 150 mm in 24 hours.
- Wadi flooding: The wadi networks upstream of Safi swelled rapidly, inundating agricultural land, destroying rural infrastructure, and flooding parts of the city.
- Human cost: Multiple fatalities were reported, with thousands displaced. The agricultural sector suffered devastating crop losses.
- Emergency response: The government activated emergency protocols, deploying military and civil protection assets for rescue and relief operations.
Mountain Snowfall
While the lowlands flooded, the Atlas Mountains received exceptional snowfall. The combination of abundant moisture and cold temperatures produced snow depths not seen in years at Ifrane, Oukaimeden, and Michlifen. Ski conditions were superb, but road closures over Atlas passes disrupted transportation and isolated some mountain communities.
January 2026: No Respite
Typically, the Moroccan rainy season features alternating wet and dry periods as depressions pass through with intervals of several days. January 2026 defied this pattern.
The Storm Train Continues
The atmospheric blocking pattern persisted, continuing to channel depressions into Morocco. January saw nine distinct weather systems cross the country, compared to a typical three to four.
Ifrane's Remarkable Record
The Middle Atlas town of Ifrane, already known for its wet winters, set a staggering record.
- Rainy days in the season: By the end of January, Ifrane had recorded 49 days with measurable precipitation since the start of the rainy season in early November, an extraordinary total that exceeded many full-season records.
- Snowfall: Heavy and frequent, keeping the surrounding cedar forests under continuous snow cover. Roads between Ifrane and Fes were closed repeatedly.
- Temperature: Despite the persistent cloud cover, temperatures were not unusually cold, hovering near seasonal averages. The precipitation was the story, not the cold.
Tangier Approaches 1,000 mm
By the end of January, Tangier's cumulative season rainfall had passed 800 mm and was tracking toward levels not seen in the instrumental record. The city's infrastructure, designed for heavy rain but not for this level of sustained precipitation, showed increasing strain. Landslides affected hillside neighborhoods, and the drainage system was overwhelmed during the most intense events.
Reservoir Recovery
The silver lining of January's deluge was a dramatic recovery in dam levels across the country. Recent strategic dams like Tiddas on the Bouregreg also contributed to the recovery of the Rabat-Casablanca corridor's reserves.
- National dam fill rate rose from below 25% in October to over 40% by the end of January.
- Key northern dams (Al Wahda, Idriss I) saw the fastest rises, approaching 60% capacity.
- Southern dams recovered more slowly, as the heaviest rain was concentrated in the north and center.
The recovery was welcome but came with caveats. Rapid inflows carried enormous sediment loads, reducing the effective storage capacity of some dams. And the water was arriving too fast for controlled management, requiring emergency spillway releases that contributed to downstream flooding.
February 2026: The Second Wave
February brought a second round of extreme weather that compounded the December and January damage.
Broadening Impact
While December and January events were concentrated in the north and center, February's storms affected a wider area.
- Souss-Massa: Heavy rainfall in the western High Atlas sent exceptional runoff down the Souss valley, flooding agricultural land around Taroudant and threatening Agadir's outskirts.
- Marrakech-Safi: Renewed wadi flooding affected communities that had already suffered in December.
- Oriental: Rain and snowmelt combined to flood parts of Oujda province and the Moulouya basin.
Cumulative Damage
The sequential nature of the winter's events created cumulative damage that exceeded what any single event would have caused.
- Infrastructure: Roads, bridges, and irrigation canals that had been damaged in December and patched in January were destroyed again in February. The cost of repeated repair far exceeded initial damage estimates.
- Agriculture: Fields that had been replanted after December flooding were submerged again, representing a double loss for farmers.
- Displacement: Communities that had returned to flood-damaged homes were forced to evacuate a second time, straining emergency shelter capacity and the psychological resilience of affected populations.
March 2026: The Season Winds Down
By March, the atmospheric pattern began to shift. The blocking configuration that had steered storms into Morocco weakened, and the jet stream lifted northward, allowing longer dry intervals between weather systems.
Final Tallies
As the rainy season drew to a close, the numbers were extraordinary.
- Tangier: Season total approximately 1,296 mm, one of the highest figures in the city's recorded history and roughly 160% of the long-term average.
- Ifrane: Over 1,400 mm with 49 significant rainy days, far exceeding normal season totals.
- National dam fill rate: Recovered to approximately 55%, a remarkable turnaround from the 25% low of October 2025, though still below full capacity.
- Chefchaouen: Season total exceeded 1,800 mm in the surrounding Rif hills, consistent with the area's status as Morocco's wettest region.
- Southern regions: Recovery was more modest. Ouarzazate, Errachidia, and the Saharan fringe received above-average but not record-breaking rainfall.
The Government Response
Morocco's government launched a comprehensive response to the winter's dual challenges of flood emergency and drought recovery.
Emergency Phase
- Search and rescue: Military and civil protection units were deployed repeatedly throughout the winter, conducting evacuations, rescuing stranded motorists, and delivering supplies to isolated communities.
- Humanitarian aid: Emergency shelters, food, and medical assistance were provided to displaced populations. International organizations, including the Red Crescent, supplemented government efforts.
- Infrastructure triage: Rapid assessment teams prioritized the repair of critical infrastructure: main highways, bridges, water supply systems, and electrical networks.
Recovery Plan
The government announced a multi-billion-dirham recovery plan with several pillars.
- Infrastructure reconstruction: Rebuilding damaged roads, bridges, and irrigation systems to higher standards, incorporating flood resilience into the design.
- Agricultural support: Compensation for farmers who lost crops and livestock, subsidized seeds and inputs for the spring planting season, and fast-tracked insurance payouts.
- Flood risk management: Accelerated investment in flood early warning systems, expanded radar coverage, and community-level preparedness programs.
- Land-use reform: Review of building permits and land-use plans in flood-prone areas, with the goal of preventing construction in high-risk zones.
Dam Management Review
The winter exposed challenges in managing Morocco's large dam network during extreme inflow events. When dams fill rapidly, operators face a difficult choice: release water preemptively and risk downstream flooding, or retain water and risk overtopping. The government initiated a review of dam operating protocols, flood routing procedures, and the communication channels between dam operators, regional authorities, and downstream communities.
What This Winter Tells Us About Climate
The temptation is to interpret winter 2025-2026 as evidence that Morocco's drought is over. The reality is more nuanced and more concerning.
The Drought Is Not Over
Despite the exceptional rainfall, Morocco's structural water deficit remains. Groundwater aquifers depleted over decades of over-extraction cannot be recharged in a single wet season. Some of the rain fell too fast to infiltrate, running off into rivers and eventually the ocean rather than replenishing underground stores. And the southern and eastern regions, where drought was most severe, received less dramatic relief than the north.
Climate Volatility Is the New Normal
What winter 2025-2026 most clearly demonstrates is increased climate volatility. The swing from multi-year drought to record flooding is not a contradiction; it is exactly what climate models predict for the Mediterranean basin.
- Average rainfall may decline, but the variability around that average is expected to increase.
- When rain comes, it will be more intense, delivered in fewer but more extreme events.
- Dry periods will be longer, punctuated by wet periods that may exceed historical norms.
This volatility is harder to manage than a simple drying trend. It requires infrastructure that can handle both extremes: reservoirs large enough to store surplus from wet years, drainage systems robust enough to handle intense rainfall, and agricultural practices flexible enough to cope with boom-and-bust precipitation cycles.
A Climate Shift?
Some meteorologists have suggested that winter 2025-2026 may represent more than a single anomalous season. Changes in Atlantic sea surface temperatures, shifts in the North Atlantic Oscillation, and the evolving position of the Azores High could signal a longer-term modification of Morocco's rainfall patterns.
It is too early to confirm this hypothesis with a single season of data. But the possibility that Morocco's climate is not simply drying but becoming more variable and more extreme is consistent with the broader scientific understanding of Mediterranean climate change. Future winters will provide additional data points, and the DGM and international research partners are studying the 2025-2026 season intensively to understand its atmospheric drivers.
Lessons Learned
Winter 2025-2026 delivered several harsh but important lessons.
- Drought and flood are not opposites; they are companions. Morocco must plan for both simultaneously, not sequentially.
- Infrastructure designed for average conditions fails during extremes. Roads, bridges, drainage systems, and dams must be engineered for the worst case, not the average case.
- Early warning saves lives, but only if warnings reach people and are acted upon. Investment in warning systems must be matched by investment in communication channels and community preparedness.
- Land-use planning is a flood mitigation tool. Building on floodplains, in wadi beds, and on unstable slopes converts weather events into human disasters. Enforcement of building codes and land-use regulations is essential.
- Water management must become more sophisticated. The ability to capture, store, and distribute water from a volatile rainfall regime requires upgraded infrastructure, better forecasting, and more flexible operating procedures.
A Season for the Record Books
Morocco's winter 2025-2026 will be remembered as a season of extremes: extreme rain, extreme snow, extreme flooding, and extreme recovery after extreme drought. It challenged the country's infrastructure, tested its emergency response systems, and forced a national reckoning with the reality of climate volatility.
The 1,296 mm measured at Tangier, the 49 rainy days at Ifrane, the catastrophic floods at Safi, and the dramatic dam recovery are all entries in a ledger that will be studied for years. They tell the story of a country at the crossroads of climatic worlds: Atlantic and Saharan, Mediterranean and continental, wet and dry. Managing this complexity is Morocco's defining environmental challenge, and winter 2025-2026 made clear that the stakes are rising.
Conclusion
The rains that Morocco desperately needed arrived with a force that Morocco was not fully prepared to handle. This paradox encapsulates the country's climate challenge: too much water and too little water are not separate problems but two faces of the same coin. The historic winter of 2025-2026, from the first hopeful November rains to the devastating February floods, demonstrated that Morocco's future will be defined not by averages but by extremes. Building the infrastructure, institutions, and resilience to manage those extremes is the task that this winter assigned to the nation.
