Potes led the Cantabrian index with 72.2 points while holding the most compromised horizon of every municipality in this batch that the model treats as observable: 6.2 degrees of terrain in front of the Sun. With the disc at 9 degrees, the effective margin came down to 2.8.

The town sits at 426 metres of average elevation at the bottom of a funnel, and the proof of how narrow that margin was lies 6.2 kilometres away: Cillorigo de Liébana, with an almost identical 98 seconds of totality, drops to -4.7 degrees and the model declares it blocked. A few kilometres and a few degrees separated a leading entry from a discarded one. What kept Potes in first place were its 99 seconds and its 20.6 per cent clear days, the best figure in the Liébana group across the 1996-2025 series, though twenty Augusts in a hundred guarantee nothing and never amounted to a forecast.
