Biscay

12 cities evaluated. Data based on the real-horizon model with the Copernicus GLO-30 DEM.

10Totality

In Biscay province, totality will cross 10 cities, 10 of them at sunset. The other 2 will see a significant partial eclipse.

Historical weather data points to basauri, galdakao and barakaldo as the clearest spots: climatology (median p25-p75 cloud cover at sunset in August, Open-Meteo ERA5) places basauri around 41% cloud cover.

The clearest western horizon belongs to getxo, where the topographic horizon sits at just 0.7° altitude at the evaluated contact — a critical figure for catching C4 with the Sun very low in August 2026.
