Calima and Strong Winds Set to Sweep the Archipelago
The Canary Islands are preparing for a day dominated by the arrival of calima (Saharan dust haze) and moderate to strong winds, with intense gusts expected in several areas. This combination is likely to impact visibility and air quality across the archipelago. Locally very strong gusts are forecast for high-altitude areas and the north-western and south-eastern slopes of the more mountainous islands. In a notable alert for La Palma, winds in the municipality of El Paso could reach speeds of 90 kilometres per hour overnight.
General Outlook: Clear Skies but Rough Seas
Generally, slightly cloudy or clear skies will predominate, though cloudy intervals are expected in low-lying areas of the north-east of the more mountainous islands, with a low probability of scattered drizzle in the early hours. At sea, a north-easterly force 5 to 6 wind is forecast, increasing to 6 or 7 in the afternoon. A swell or heavy swell will tend towards a rough sea, with a northerly ground swell of between one and three metres.
