Spain's AEMET releases cloud‑risk map for August 12 total solar eclipse

AEMET released a statistical map based on 16 years of observations, satellite data and ERA5 reanalysis (adjusted with cloud‑mask products) that shows the probability of cloud cover across Spain during the key 17:00‑20:00 UTC period of the total solar eclipse on 12 August 2026.

The map indicates a higher risk of clouds (30‑50 % chance) along the northern coast – Galicia, Asturias, Cantabria and the Basque Country – while the southern half of the peninsula is expected to be clearer, with over 60 % chance of cloud‑free skies. Central regions such as Castilla‑La Mancha, Castilla‑y‑León and the Ebro valley have intermediate probabilities.

AEMET stresses that the map is statistical, not a weather forecast; precise forecasts will be issued a few days before the eclipse.

Tourism guides also point to remote spots in Lugo province – Chantada and the Ribeira Sacra, the Muras area, Os Ancares and O Courel – as ideal low‑light‑pollution locations for viewing the eclipse away from crowds, with local accommodations preparing for increased demand.
