The Canary Islands are set to experience the effects of an Atlantic storm system beginning Friday, 9 May 2025, according to the meteorological portal Eltiempo.es. While the State Meteorological Agency (AEMET) anticipates no extreme weather phenomena, both sources confirm a period of unstable conditions, particularly affecting the western and mountainous islands. The storm is expected to be short-lived, with improving weather by the end of the weekend.
Friday Forecast – 9 May
According to Eltiempo.es, the first rain showers will arrive on the western islands, including La Palma and El Hierro, and gradually spread eastwards over the course of the weekend. Though the episode is expected to dissipate by Sunday, isolated thunderstorms cannot be ruled out in certain parts of the archipelago.
The AEMET also reports increasing cloud cover across the Canary Islands, with light and occasional rainfall forecast in various areas. While Lanzarote and Fuerteventura are likely to enjoy clearer skies, high-altitude clouds will increase during the day, particularly inland and along the eastern flanks, where isolated rain may develop.
- Gran Canaria, Tenerife, and La Palma: Persistent cloudy intervals, with a higher probability of light, scattered rain.
- Temperatures: Largely stable, with minor drops expected in the eastern islands.
- Winds: Generally light, turning moderate in the southeast and northwest during the afternoon. Strong gusts are forecast for the highlands of La Palma and the central peaks of Tenerife, particularly after midday.
Saturday Forecast – 10 May
On Saturday, overcast skies will continue to dominate the western slopes of the mountainous islands, as well as the eastern sectors of the central islands during the afternoon. Rain will range from light to locally moderate, particularly in elevated regions.
- Temperature trends: A slight increase is expected across most islands, except in La Palma, where a modest drop in daytime highs is likely.
- Winds: Predominantly from the west, with intense gusts in low-lying areas and especially strong conditions in mountain zones.
Sunday Forecast – 11 May
By Sunday, the storm will begin to weaken, but cloudy skies will persist, especially on the eastern slopes during the afternoon and on the western islands later in the day. Rainfall will remain light and sporadic, concentrated on:
- The northwestern slopes during the morning
- The eastern zones in the afternoon
Winds are expected to gradually subside, though very strong gusts may still occur on the summits of Tenerife.
Temperature Outlook
- Minimum temperatures in the provincial capitals (Las Palmas and Santa Cruz) will hover around 18 °C
- Maximum temperatures:
- 22 °C in Las Palmas de Gran Canaria
- Up to 25 °C in Santa Cruz de Tenerife
Overall, the approaching Atlantic storm is likely to bring brief but noticeable weather instability, with overcast skies, localised rainfall, and strong winds at altitude, particularly on Friday and Saturday. Conditions are expected to gradually improve by Sunday evening.
