The eclipse runs from about 19:23 to 21:07 CEST, with maximum at around 20:17 and the Sun ~3° above the west-northwest horizon. The Sun sets at 20:41 CEST, during the eclipse, so the later stages happen below the horizon — an open west-northwest view is essential.

Die besten Beobachtungsplätze

Lake Constance promenade

Lakeside · open water

Widest low horizon locally

The lakefront gives a flat, open sightline across the water — exactly what a Sun only 3° up needs.

Mainau island

Island · gardens

Open water on all sides

The flower island in the lake has open horizons and an unusual setting.

Bodanrück heights

Elevated · above the lake

Height over the water

The ridge north of Konstanz lifts you above the lake haze for a longer view.

Reichenau island

Island · flat and open

UNESCO setting, clear sightline

The monastery island is low, flat and surrounded by water, giving a clean western horizon.

West toward Freiburg

Deeper coverage

~90%

Coverage deepens toward Germany's south-west corner — Freiburg and the Rhine plain see the most.

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

Die Wetterprognose

Wird der Himmel klar sein?

Southern Germany is usually warmer and clearer than the north, though Alpine and Black Forest cloud can build in the evening.

The deciding factor here is simply whether the sky is clear at the right moment. Check the forecast in the final 48 hours and, if you can, keep the option of moving to a gap in the cloud.

Konstanz & Lake Constance Sonnenfinsternis FAQ

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

No. Konstanz is outside the path of totality and sees a partial eclipse, with about 90.0% of the Sun covered at maximum. It is a striking sight through eclipse glasses, but the corona does not appear and the sky does not go dark. The path of totality crosses northern Spain.

What time is the eclipse in Konstanz?

The partial phase begins at about 19:23 CEST and maximum — 90.0% coverage — comes at roughly 20:17 CEST. The Sun sets at 20:41 CEST, during the eclipse, so the later stages happen below the horizon — an open west-northwest view is essential.

Do I need eclipse glasses in Konstanz?

Yes, for the entire eclipse without exception. Because the Sun is never fully covered, there is never a safe moment to look with the naked eye. Even at 90.0% 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 Konstanz?

The Sun is only about 3° above the horizon, so you need an open, unobstructed view to the west-northwest. Buildings, hills and trees in that direction will hide the deepest phase.

Will the weather be clear in Konstanz on eclipse day?

Southern Germany is usually warmer and clearer than the north, though Alpine and Black Forest cloud can build in the evening.
