The August 12, 2026 total solar eclipse in Karrantza Harana/Valle de Carranza (Bizkaia)

Karrantza had the best historical odds of anywhere on the Biscayan podium: 19.5% of open sky across the 1996-2025 record, ranking 13th among the 56 municipalities inside the band. That number deserves to be read without enthusiasm. Nineteen in a hundred means that across thirty years barely six 12 Augusts arrived with an open sky. Topping Bizkaia on this metric is winning a race the whole province ran uphill, and it explains why its score stops at 58.8 out of 100 despite 63 seconds of totality.

Those 63 seconds are the third best provincial figure, with totality from 20:27:10 to 20:28:13. The Sun stood 9 degrees above the horizon, the highest it reached anywhere in Bizkaia and shared only with Lanestosa, and the eclipse did end in the sky: fourth contact came at 21:20:13, before sunset. Working against it were the horizon clearance of 4.1 degrees and average cloud cover of 58.5%, with rain in 58.0% of the years in the series.
