Significant Weather Changes in Morocco

As September dawned, Morocco experienced a notable shift in its weather patterns following a sweltering August, as indicated by the General Directorate of Meteorology (DGM). The onset of this new month brought with it a combination of exceptionally high temperatures alongside sporadic yet intense thunderstorms, marking a dramatic change in the atmospheric conditions across the region.

During August, much of Morocco, particularly the inland areas, southeastern regions, and Saharan provinces, endured persistent heat, setting the stage for a transition at the beginning of September. A convergence of several atmospheric factors contributed to a more unstable weather environment. According to the DGM’s comprehensive weather overview for early September 2026, the expansion of the Saharan thermal low pressure system northward, coupled with southerly to southeasterly winds, facilitated the introduction of extremely hot air into Morocco's interior.

Atmospheric Dynamics and Thunderstorm Formation

The influence of the Chergui winds also played a significant role in this meteorological shift, while pockets of cooler air began to infiltrate the upper atmosphere. Concurrently, warm and humid tropical air masses ascended into the mid-levels of the atmosphere, resulting in an increased concentration of water vapor. This rise in humidity intensified the sensation of heat, particularly along the coastal regions and the expansive Atlantic plains.

This unique combination of atmospheric conditions, along with the geographical influence of Morocco's mountainous terrain, created an ideal environment for thunderstorm development. Such storms were particularly prevalent during the afternoons and early evenings over the High Atlas and Middle Atlas mountain ranges, with some storm cells delivering heavy hail and powerful gusts of wind. The DGM elaborated on how thunderstorms can occur even amid high ground-level temperatures, explaining that heat acts as a catalyst for convection while the influx of tropical humidity provides the necessary moisture for the rapid development of convective clouds.

On September 3rd, temperatures soared to unprecedented levels, with Sidi Slimane recording an astonishing 47.1°C, followed closely by Kenitra at 45.1°C and Sale at 44.3°C. These extreme temperatures set new records for the month of September in their respective provinces. The meteorological agency characterized September as a transitional period, where the lingering effects of summer, such as the oppressive Saharan heat and tropical air, begin to interact with the first incursions of cooler air at higher altitudes. This dynamic interplay can lead to stark temperature contrasts and contribute to the occurrence of severe weather phenomena.
