The August 12, 2026 total solar eclipse in Lanestosa (Bizkaia)

Lanestosa won its province and still scored 59.6 out of 100. That contrast is the clearest way to understand what happened to Bizkaia in this eclipse. Its 66 seconds under the umbra, from 20:27:10 to 20:28:16, were the maximum among the 56 Biscayan municipalities inside the band, yet Guadalajara's leader reached 83.7 points with 103 seconds and more than triple the historical chance of open sky. Lanestosa's ceiling was not set by its geometry but by its climate: the thirty-year record leaves only 18.5% of 12 Augusts clear.

It is also the westernmost point of the territory, and the clock shows it: it was the last Biscayan municipality to close the eclipse, with fourth contact at 21:20:15 and the Sun still visible. At 446 metres, with an average minimum of 14.6 degrees and rain recorded in 59.2% of the years in the series, it is the coolest and wettest of the six Biscayan entries on this list. The terrain model set aside 4.9 degrees of slack for a Sun that barely reached 9.
