August 12, 2026 Eclipse: Setting Sun in Lisbon, Turkey's Wait & Eye Safety Guide
Those who remember the legendary eclipse of 1999 know that the sudden darkening of the sky and the silence of birds leave an unforgettable impression. Europe is now preparing to host a major total solar eclipse for the first time in 27 years.
Passing through the Arctic, Greenland, Iceland, and Spain, this celestial event on August 12, 2026, will graze the northern tip of Portugal. Let's discuss the details of what to expect in Lisbon, the situation in Turkey, and how to safely enjoy this visual spectacle without harming our eyes.
What's the Situation in Lisbon? It Will Darken Just as the Sun Sets!
To be honest, Lisbon lies slightly south of the totality path. The sky won't go pitch black, and we won't see the famous solar corona. However, a massive event awaits us: exactly 94.5% of the Sun's disk will be covered.
A silvery, strange twilight will cover the environment. The most fascinating and challenging part is the timing. In Lisbon local time (WEST), the process unfolds as follows:
- 18:39 – The Moon starts biting the Sun (Sun is 21° high above the horizon).
- 19:36 (Peak Moment) – Obscuration reaches 94.5%. The Sun is low (10.3°) and shifted toward the West-Northwest.
- 20:29 – Eclipse ends.
- 20:34 – Sunset.
This means the peak of the eclipse happens right before sunset. Anyone with a building or hill blocking the western horizon won't see anything.
Best Observation Spots in Lisbon:
- Miradouro da Senhora do Monte: The highest viewpoint in the city with an entirely open western panorama.
- Cristo Rei (Almada): Across the river, offering great elevation and an ocean-facing perspective.
- Cabo da Roca & Praia do Guincho: Perfect if you want to photograph it setting over the ocean at Europe's westernmost point.
- Parque Eduardo VII: A great upper terrace alternative for those staying in the city center.
Will Turkey Be Able to See This Eclipse?
Short answer: No.
During the August 12, 2026 event, the Moon's penumbra unfortunately doesn't reach the Eastern Mediterranean. The Sun will either have already set or the shadow won't pass over us.
When Will We See One? (Note August 2, 2027!)
No need to worry, because a brilliant rematch is coming up soon. The eclipse on Monday, August 2, 2027, stretching from Gibraltar to Egypt, will be one of the longest total eclipses of the century (lasting 6 minutes and 23 seconds in Luxor, Egypt!).
Though Turkey is not directly on the center line, southern and western provinces will experience substantial daylight dimming:
- İzmir: 71.1% obscuration (Peak time: 12:38)
- Antalya: 69.5% - 76% obscuration (Peak time: 12:46)
- İstanbul: 59.3% obscuration (Peak time: 12:39)
- Ankara: 56.3% obscuration (Peak time: 12:46)
(Note: The ultimate show for Turkey will be on June 1, 2030, when an Annular Solar Eclipse passes directly over Istanbul and Marmara!)
The Most Important Part: Don't Risk Your Eyes!
Thinking "94% of the Sun is covered, I don't need a filter anymore" would be the mistake of a lifetime. Even that remaining 5% is enough to burn your retina. Worse, your retina has no pain receptors; you feel nothing while burning, and only realize the damage the next day when blind spots appear.
Never Use:
- X-ray films, CDs/DVDs, smoked glass, aluminum foil.
- Layering 3-4 regular sunglasses.
Even if they block visible light, they do not filter infrared (IR) and ultraviolet (UV) rays. In the darkness, your pupils dilate, channeling harmful rays straight inside.
Right and Safe Equipment:
- You must use officially certified ISO 12312-2 eclipse glasses.
- For cameras, binoculars, or telescopes: The filter must go in front of the lens where light first enters, never on the eyepiece. Otherwise, optics act like a magnifying glass, instantly frying the sensor and blinding you in milliseconds.
