Portugal's First Total Solar Eclipse Since 1912 Falls on 12 August, but Totality Grazes Only a Corner of Montesinho

On 12 August, Portugal sees its first total solar eclipse since 1912 — but totality lasts just 26 seconds and only over a sliver of the Montesinho park near Bragança. The rest of the mainland gets a deep partial: 98% in Porto, 95% in Lisbon, 93% in the Algarve. Book early and mind your eyes.

The Algarve's Sea Turns Colder Than the North Coast as Summer Upwelling Flips Portugal's Usual Temperature Map

The Algarve's sea is currently colder than the west and north coasts — roughly 18-19°C versus 20-21°C — an inversion of the usual summer pattern. The cause is the 'nortada' wind driving coastal upwelling, which pushes warm surface water offshore and pulls colder water up from the deep.

CIVISA raised the Pico volcano's alert level to V1 on Thursday after a swarm of small earthquakes from 05:48 on the mountain's southern flank. The strongest, magnitude 2.4, was felt at intensity III/IV in São Caetano and Candelária. The alert signals closer monitoring, not an imminent eruption.
