Where to watch the 2026 solar eclipse in Lisbon

Lisbon sees a deep partial eclipse of around 94.5% on 12 August 2026, with the Sun 10° above the horizon over the Atlantic — a fine sight from the city's famous viewpoints, though the path of totality lies well to the north.

Durée~1h 49m of partial eclipseThis is the full partial eclipse from first to last contact. There is no totality here — the Sun is never completely covered, so there is no corona and no moment when it is safe to look without protection.

Où s'installer

Les meilleurs endroits pour observer

Miradouro da Senhora do Monte

Elevated · highest miradouro

Widest western panorama

The highest of Lisbon's viewpoints, with a broad sweep west over the castle, the city and the Tejo — the best combination of height and direction.

Cristo Rei, Almada

Elevated · across the river

Panorama back over Lisbon

The statue's platform across the Tejo gives a commanding view back over the city and the river mouth toward the ocean.

Cabo da Roca

Headland · westernmost

Continental Europe's western tip

The most westerly point of mainland Europe, with completely open Atlantic horizons — the definitive setting for a sunset eclipse, about 45 minutes from the city.

Praia do Guincho / Cascais coast

Coast · open ocean

Unobstructed sea horizon

The exposed Atlantic coast west of Lisbon gives wide open sea views and beach space.

North for deeper coverage

More of the Sun covered

Porto ~98%

Coverage increases markedly toward the north — Porto and Braga see around 98%, and the path of totality clips the far north-east near Bragança.

Local astronomy societies and science centres often organise safe public viewing with filtered telescopes — worth checking closer to the date.

La météo

Le ciel sera-t-il dégagé ?

Lisbon has reliably clear August evenings and no shortage of elevated west-facing viewpoints — the city is practically designed for watching a low western Sun.

Coverage here is lower than the north of the country at around 94.5%.

Atlantic haze on the horizon is the main local risk.

Glasses stay ON for the entire eclipse — there is no safe moment here
A reasonable view west — the Sun is ~10° up, so gaps in cloud are enough
Arrive before 18:39 to catch first contact

Check the cloud forecast in the final 48 hours
Never look through a camera, phone or binoculars without a proper solar filter
Pinhole projection is a safe way for groups to watch together
If you want totality, it is northern Spain — not here

FAQ sur l'éclipse en Lisbon

Will Lisbon see a total solar eclipse on 12 August 2026?

No. Lisbon is outside the path of totality and sees a partial eclipse, with about 94.5% of the Sun covered at maximum. That is a striking sight through eclipse glasses, but it is not totality — the corona does not appear, the sky does not go dark, and there is no moment when it is safe to look without protection. The path of totality crosses northern Spain.

What time is the eclipse in Lisbon?

The partial phase begins at about 18:39 WEST and maximum — 94.5% coverage — comes at roughly 19:35 WEST. The whole eclipse finishes before sunset at 20:34 WEST, so you are not racing the horizon here.

Do I need eclipse glasses in Lisbon?

Yes, for the entire eclipse without exception. This is the most important difference from a total eclipse: because the Sun is never fully covered, there is never a safe moment to look with the naked eye. Even at 94.5% coverage the remaining sliver is dangerously bright. Certified ISO 12312-2 / CE glasses stay on from start to finish.

Where should I watch from in Lisbon?

With the Sun about 10° above the horizon at maximum, you have some flexibility — a break in the cloud matters more than a perfect horizon. Higher, open ground still gives the best view.

Is Lisbon a good place to watch the 2026 eclipse?

It is a pleasant one, but not the best in Portugal. Lisbon sees about 94.5% coverage — noticeably less than Porto's 98% — though it does have the Sun 10° up, dependable August weather and outstanding west-facing viewpoints. If depth matters most, head north.

Will the weather be clear in Lisbon on eclipse day?

Central and southern Portugal are reliably dry and sunny in mid-August, with clear evening skies the norm.
