Marrakech Faces Rising Heat as Its Historic Medina Enters a New Climate Era

Marrakech has an even bigger climate problem than the viral tale of underground cooling passages. There is not a single proven piece of official evidence of the installation of a city-wide system of underground water-misting and geothermal cooling in the Medina of Marrakech by the Marrakech-Safi Regional Council as of 2 October 2026. Similarly, there is no reliable proof of 6°C cooling achieved through the use of geothermal cooling infrastructure in this area, along with rooftop solar farms providing electricity to geothermal cooling pipes under the souks. However, what is known is quite meaningful. Morocco has been planning its climate adaptation strategies in the Marrakech-Safi region, while Marrakech has to deal with higher temperatures, water stress and protection of one of the key historic areas of the country. The difference does matter to tourists. While the Medina of Marrakech remains an architectural heritage site featuring narrow shaded passages and pedestrian streets, the climate impact is getting more and more relevant.

Marrakech Is Preparing for a Hotter Climate

The Moroccan Ministry of Energy Transition and Sustainable Development published a climate-resilient adaptation and development plan for Marrakech-Safi in May 2026.

The plan reflects a wider shift in how the region is approaching climate risk. Marrakech faces exposure to extreme temperatures, drought, flooding and other climate-related pressures, making adaptation increasingly important for infrastructure, public spaces and urban planning.

The issue has become particularly relevant after repeated heatwaves across Morocco during 2026.

Official road-weather information from Morocco’s motorway authority showed a heatwave warning affecting the Berrechid-Marrakech and Marrakech-Agadir corridors on 2 October, alongside other parts of the country. That provides a more credible explanation for the renewed attention around heat in Marrakech than the unverified claim of a newly activated underground cooling system.

The Medina Already Has Natural Cooling Features

Marrakech’s historic Medina was not designed around modern air-conditioning.

Its narrow lanes, dense building arrangement, shaded routes, courtyards and traditional construction have long influenced how people experience heat within the historic centre.

The Medina of Marrakesh is a UNESCO World Heritage property, with landmarks including the Koutoubia Mosque, Bahia Palace, Badiâ Palace, Saadian Tombs and Ben Youssef Madrasa.

Its architectural character is particularly important when considering future climate adaptation. Modern interventions inside a historic environment cannot simply be treated like infrastructure projects in a newly developed district.

Any major underground engineering, water network or mechanical cooling system would need careful consideration of archaeological conditions, historic structures, drainage, water consumption and heritage protection.

That is one reason the alleged 6°C cooling project requires caution. No authoritative documentation located in the current official record confirms such an installation.

Water Adds Another Layer to the Challenge

Cooling Marrakech’s outdoor spaces also has to be considered alongside Morocco’s continuing water pressures.

Heat increases demand for water while drought can reduce available supplies. For a destination heavily dependent on tourism, hospitality and outdoor activity, the relationship between cooling and water management is particularly important.

A large-scale water-misting network across the Medina would therefore represent a substantial infrastructure decision, especially if it operated continuously during periods of extreme heat.

No such project was identified in the current official climate adaptation material reviewed for Marrakech-Safi.

Instead, the region’s climate planning points towards a broader resilience approach rather than a single technology-led solution.

For visitors, this could mean that future improvements are more likely to involve urban design, shaded public areas, water management, greener spaces, mobility planning and other adaptation measures alongside heritage conservation.

Heritage Protection Remains Central

The Medina is also dealing with the longer-term consequences of the September 2023 earthquake.

Recent UNESCO documentation notes progress in conservation and restoration work following the earthquake and calls for detailed technical and scientific documentation of restoration interventions.

The World Heritage Committee has also encouraged Morocco to prepare a sustainable tourism management plan for the property as part of its wider management framework.

That creates an important connection between climate resilience and tourism.

The challenge is not simply keeping visitors comfortable during hot weather. Marrakech must also ensure that changes designed to improve urban resilience do not compromise the historic character that makes the Medina attractive in the first place.

What Travellers Can Expect

All this being said, the lesson for travellers planning visits to Marrakech is fairly obvious. There will continue to be a need to consider the heat when planning any activities around the Medina, in particular at the peak of hot periods during the day. Taking walks at dawn or dusk may prove to be easier, and one may employ traditional riads, courtyards, museums, and souks to escape from the heat in the streets. The Medina is definitely one of the most famous attractions in Marrakech, but in terms of its future, it will depend a lot on the interaction between the issues of heritage conservation, tourism, water resources, and climate change management. As bizarre as the story with smart underground tunnels seemed, there is substance to the real story in its own way. There is a serious climate problem facing Marrakech, and it is shaping the way towards a regional adaptation strategy.
