Tunisia is bracing for a shift in weather conditions, with forecasts predicting localized fog, cloud cover, and potential rainfall across various regions. The anticipated drop in temperatures follows a period of relatively mild weather, prompting authorities to advise residents to prepare for cooler conditions. This comes as the Institut National de la Météorologie (INM) continues to monitor atmospheric patterns and provide regular updates to the public.
The INM, established in 1974 but with roots tracing back to the 19th century, plays a crucial role in Tunisia’s meteorological and seismological monitoring. As the nation’s official weather service, it maintains a network of observation stations and collaborates with international organizations to deliver accurate forecasts and warnings. The institute’s current director general is Ahmed Hmam.
Weather Outlook for Friday, March 13th
According to the latest bulletin from the INM, issued Friday, March 13th, localized fog is expected to form in the morning. Simultaneously, the southeast regions will experience periods of dense cloud cover. Later in the afternoon, rainfall is anticipated to spread across northern and central Tunisia, with a possibility of thunderstorms along the northern coastal areas. The remainder of the country will likely see passing clouds.
Winds will be a significant factor, blowing from the east at a relatively strong pace near the coast and across the south. These winds are expected to stir up localized sandstorms, reducing visibility in those areas. Elsewhere, wind speeds will remain moderate to light. The sea conditions will be choppy, with the Gulf of Gabès experiencing agitated waters and the rest of the coastline facing a moderate swell.
Temperatures are expected to decrease slightly throughout the day. Maximum temperatures will generally range between 17 and 22 degrees Celsius (63 and 72 degrees Fahrenheit), while higher elevations may see temperatures around 15 degrees Celsius (59 degrees Fahrenheit). This slight dip in temperature marks a change from recent warmer conditions, and residents are advised to dress accordingly.
Regional Variations and Potential Impacts
The northern coastal regions are particularly susceptible to the forecasted thunderstorms. These storms, while potentially localized, could bring heavy downpours and gusty winds, impacting maritime activities and potentially causing localized flooding. The INM advises mariners to exercise caution and heed any warnings issued by port authorities. The agitated sea conditions in the Gulf of Gabès also pose a risk to smaller vessels.
The sandstorms in the south, driven by the easterly winds, could disrupt transportation and visibility. Individuals with respiratory sensitivities are advised to accept precautions, such as wearing masks and limiting outdoor exposure during periods of high dust concentration. The INM regularly monitors dust levels and issues alerts when conditions warrant.
While the central regions are expected to receive less rainfall than the north, they will still experience increased cloud cover and a slight drop in temperature. Agricultural activities in these areas may be affected by the changing weather conditions, and farmers are encouraged to monitor forecasts closely.
Longer-Term Climate Trends and Recent Data
The current weather pattern follows a period of fluctuating temperatures and precipitation in Tunisia. According to a preliminary climatological bulletin released by the INM on February 13th, 2026, January 2026 was characterized by exceptional rainfall in the north and central regions, leading to notable hydrological impacts. The INM’s website provides detailed monthly climate reports and data analysis.
The average national temperature in January 2026 reached 12.7°C (54.9°F), representing a positive anomaly of +1.4°C (2.5°F) compared to the reference average of 11.3°C (52.3°F). December 2025 also saw temperatures above the normal range, with an average of 13.3°C (55.9°F), exceeding the typical 12.5°C (54.5°F). These warmer temperatures, coupled with increased rainfall, highlight the ongoing climate variability affecting the region.
The Role of the INM
The Institut National de la Météorologie plays a vital role in understanding and responding to these climate trends. Founded in 1974, the INM has evolved from a network established in the 19th century, continually adapting to advancements in meteorological science and technology. The institute’s function extends beyond daily weather forecasting to include research in meteorology and geophysics, as well as the issuance of maritime and aeronautical forecasts. The INM’s official website serves as a primary source of information for weather updates, climate data, and related advisories.
Looking Ahead
The INM is continuing to monitor the evolving weather situation and will provide updated forecasts as needed. Residents are encouraged to stay informed by checking the INM’s website and following official weather alerts. The next significant update is expected on Saturday, March 14th, providing a more detailed outlook for the weekend.
As Tunisia navigates these changing weather conditions, the INM’s role in providing accurate and timely information remains crucial for ensuring public safety and supporting economic activities. The institute’s commitment to scientific research and international collaboration will be essential in addressing the challenges posed by climate variability and ensuring a sustainable future for the country.
