A recent drop in nighttime temperatures across Morocco has sparked debate among environmental researchers, who warn against reading the shift as a natural return to stable seasonal cycles.
Specialists in environmental and sustainable development sciences told Hespress AR that the unusual cool nights during the last week of August are instead part of a broader pattern of climate disruption. They cautioned that the fluctuations should not be mistaken for a sign of recovery.
“The cooling, though seasonal in appearance, is embedded in an unstable trend that has characterized the climate in recent years,” the researchers said, noting abnormal swings between daytime heat and nighttime chill. They urged households and policymakers to adapt with flexible strategies in energy use and forward planning to reduce the impact of climate volatility.
Mustapha Benraml, president of the Eco-Lighthouses Association, said Moroccans have felt a disruption in seasonal rhythms in recent years. Heat waves have extended well into October and November, blurring the line between summer and fall.
“With the recent cooling during summer nights in 2025, people are beginning to sense the return of a more regular climate pattern,” Benraml told Hespress AR. “The relative moderation in weather could signal a gradual comeback of traditional seasonal balance, with autumn revealing itself through cool breezes and refreshing nights after a long, exhausting summer.”
Still, he urged caution, stressing that climate patterns remain highly unpredictable. “Sudden heat waves can reappear even after people feel the summer has ended,” he said. “Seasonal overlap will continue, shaped by global warming and shifts in atmospheric pressure.”
Benraml added that farmers in particular should closely monitor forecasts and adjust planting and irrigation schedules to avoid losses. He also called for stronger public health awareness campaigns to protect children, the elderly and people with chronic illnesses from sudden changes in temperature.
Other experts see the current cooling as a typical seasonal transition. Fouad Ezzahrani, a researcher in environmental and sustainable development sciences, said marine air masses from the west have lowered temperatures, in line with forecasts.
“This is a common feature of Morocco’s climate at the end of summer,” Ezzahrani said. “The cooling is reinforced by cold currents from the Canary Islands, which help moderate coastal heat. Such changes are signs of an approaching new season.”
He noted that transitional periods often bring climate variability. “We saw a similar situation in 2024, with significant rainfall in September and October that improved dam reserves,” he said. But he cautioned that overall rainfall has been decreasing in recent years, with irregular distribution across the wet season.
Ezzahrani warned that a single rainy year cannot offset years of drought. Morocco’s dam reserves currently stand at about 35 percent capacity. Rising heat, he added, intensifies evaporation and places more stress on already limited water resources.
“The impact of climate change is no longer theoretical, it is a lived reality,” he said. “We may hope for a rainy season, but we cannot ignore the long-term effects of global warming.”
