Lebanon Braces for Dramatic Temperature Swing Followed by Spring Weather Instability

Residents across Lebanon should prepare for notable weather swings in the coming days, beginning with unseasonably warm conditions before conditions destabilize mid-week, bringing rain and stronger winds to the country.

Muhammad Kanj, head of the Surface Estimates Department at Beirut Airport's Meteorological Department, outlined the expected pattern in recent remarks. Sunday's forecast calls for partly cloudy skies with high clouds overhead, accompanied by temperatures that will climb considerably above seasonal norms, particularly across southern and inland areas. Humidity levels are expected to decline during this period.

Wind activity will intensify, with gusts potentially reaching 75 kilometers per hour, especially in the northern regions. Kanj warned that dust particles may become suspended in the atmosphere as winds pick up.

The temperature increases will be substantial across much of the country. Most regions will see rises between 4 and 6 degrees above normal, with mountainous areas experiencing increases of 4 to 5 degrees. Zahle could see particularly dramatic warming, with temperatures potentially reaching 30 degrees—a jump of approximately 7 degrees above average. Southern regions are anticipated to warm by roughly 5 degrees.

By Monday, the pattern will shift sharply. Temperatures are forecast to drop significantly while humidity climbs, creating conditions favorable for fog formation in highland areas. Wind speeds will remain elevated at times, potentially reaching 50 kilometers per hour, with some atmospheric dust persisting.

Tuesday's weather is expected to remain partly cloudy with continued fog in elevated regions.

The more substantial change arrives Wednesday and Thursday, when a relatively cold air mass will move into the region. This system will generate active winds and scattered rain showers, marking a return to spring's characteristic instability. Though these weather fluctuations will be moderate in scope, they will be sufficient to reestablish Lebanon's typical volatile spring conditions.
