Muscat – Civil Aviation Authority (CAA) has issued a weather alert confirming that the Sultanate will be impacted by the season’s first cold wave beginning on Friday, December 19, 2025. This meteorological shift is driven by the arrival of a cold air mass that is expected to cause a significant and noticeable drop in temperatures across most governorates. Data released by the National Multi-Hazard Early Warning Centre indicates that while the low-pressure system’s centre is projected to move away by Saturday, the cooling effect will intensify.
Comparative forecasts highlight a sharp decline in temperatures between Wednesday and Saturday morning. In Muscat, temperatures are expected to fall from 23°C to 17°C, while more dramatic decreases will be felt in the mountainous Saiq region, where mercury levels will plunge from 6°C to a near-freezing 2°C.
