Biscay
14 cities evaluated. Data based on the real-horizon model with SRTM 30 m.
In Biscay province, totality will cross 13 cities, 13 of them at sunset. The other 1 cities will see a significant partial eclipse.
Historical weather data points to santutxu, bilbao and eibar as the clearest spots: climatology (median p25-p75 cloud cover at sunset in August, Open-Meteo ERA5) places santutxu around 4% cloud cover, well below the Biscay average.
The clearest western horizon belongs to algorta, where the topographic horizon sits at just 0.2° altitude at the evaluated contact — a critical figure for catching C4 with the Sun very low in August 2026.
