I'm one of the two developers of a weather app, so we had cloud data for the whole path and turned it into a plain page: https://forecastbar.com/eclipse-2026/ It gives cloud cover at the actual eclipse hour rather than a daily average, city by city, free and nothing to install.

As of tonight it splits sharply. Iceland is largely a write-off: Reykjavik and the Westman Islands are both 98% cloud at eclipse hour and flat all evening, so it isn't a timing problem you can wait out. The Westfjords are the exception — Ísafjörður is 75%, still poor but the best number in the country by a wide margin, and it's inside totality at about 1m33s.

Northern Spain is the good half: Burgos 8%, Zaragoza 8%, Bilbao 11%, Tarragona 13%. Palma de Mallorca is at 1% and it's in the path; Madrid and Lisbon, just outside it, are 1% too.

It's one commercial model four days out, so treat it as a second opinion. Where it disagrees with AEMET or the Met Office, believe them. We refresh it each morning until Wednesday.
