Yellow Warning for Coastal Conditions in the Canary Islands
The State Meteorological Agency (Aemet) has issued a yellow warning for coastal phenomena across the Canary Islands today, 20 July. This warning impacts the eastern, southern, and western regions of both Tenerife and Gran Canaria.
Strong north-easterly winds and rough seas are expected throughout the day, particularly in the channel between the two islands. Winds may reach force 7, leading to challenging sea conditions and heavy swells in exposed coastal areas. The inter-island channel will feel the most significant effects, prompting a low-risk yellow warning for coastal and nautical zones.
While much of the archipelago will experience mostly clear to partly cloudy skies, low cloud cover is anticipated on the northern slopes during the early and late hours. Additionally, calima—dust in the atmosphere—will create hazy conditions, mainly at higher elevations.
Moderate to strong trade winds are forecasted in the south-eastern and north-western areas of the larger islands, particularly affecting parts of Lanzarote and the Jandía peninsula in Fuerteventura. Gusts in these areas may be very strong, especially during dawn and dusk.
Temperatures are expected to rise slightly, especially on eastern and inland slopes. In Gran Canaria, southern and western regions could see temperatures reaching or exceeding 34°C. Other areas like southern Tenerife, Lanzarote, and Fuerteventura are forecasted to approach or exceed 30°C.
Aemet’s bulletin specifies that the yellow warning covers maritime areas where wind gusts may hit between 50 and 61 kilometres per hour. In Tenerife, the warning applies to the eastern, southern, and western parts, with the most significant effects expected south of the channel dividing the islands. The warning is due to expire at 00:59 on Tuesday, 21 July, the same time set for Gran Canaria’s affected coastal areas.
At sea, winds of force 4 to 6 are anticipated, increasing to force 7 offshore, leading to swells of one to two metres. Authorities are urging caution in coastal areas and advising the public to stay updated on the situation as the day unfolds.
