August 12, 2026 eclipse guide
The Moon's shadow sweeps from Greenland and Iceland to Spain at sunset — Europe's first widely accessible total eclipse since 1999. Where you stand changes everything.
Facts cross-checked against NASA GSFC, timeanddate, AAS safety guidance, Spain's IGN/AEMET resources, EclipseAtlas, Eclipsophile, and local planning sources. Roughly about 15 million people live inside the path of totality.

Jump to sectionI want the science
Understand totality, the corona, Saros 126, and the perigee Moon.
Jump to sectionWhy it matters
In Iceland and Greenland, the Sun is higher but weather and logistics are tougher. In Spain, August skies can be friendly — but the Sun sets during totality, so horizon, haze, and terrain matter as much as the centerline.
Europe's return
The first total solar eclipse visible from mainland Europe since 1999. Spain will likely see the largest visitor surge in eclipse history.
The corona is the prize
During totality the corona — the Sun's outer atmosphere — blazes into view as a pale, structured glow. No partial eclipse ever shows it.
Clear sky beats duration
A 90-second totality under open sky beats two minutes behind cloud. Mobility and forecast discipline matter as much as site selection.
99% is not totality
A 99% partial eclipse is bright, safe to look at only through viewers, and reveals no corona. The boundary is hard.
Path and timing
Global eclipse tables are useful for orientation, but they are not a local observing plan. Use a map for your exact pin and remember that published calculations can differ by a few seconds because of delta-T assumptions, ephemerides, and lunar limb treatment.

Global UTC stages
These are global milestones, not the times for one city. Each row happens at a different place along the eclipse track.
Where to go
The best site is the one where geometry, weather, horizon, access, and safety all work together. The path is a corridor; your plan should be a corridor too.
Expedition
Scoresby Sund, fjords, sea ice, and ship positioning make this one of the most dramatic ways to experience the shadow, but it is not a flexible road trip. Weather, ice, environmental rules, and the captain's final position matter.
Best next step: Choose operators that state their eclipse-day positioning plan and backup logic.
Higher Sun, harder weather
Reykjavik gets just over a minute of totality; western Iceland, Snaefellsnes, Reykjanes, and the Westfjords can get longer. The Sun is higher than in Spain, so breaks in cloud are more useful, but mobility and forecast discipline are everything.
Best next step: Watch Icelandic cloud forecasts, stay mobile, and avoid committing to a cliff or remote road without a weather exit.
Most accessible
Spain will likely host the largest number of viewers. Inland areas such as the northern Meseta and Ebro Valley have strong planning appeal, while the Cantabrian coast is more cloud-sensitive. The low western Sun makes horizon checks essential.
Best next step: Treat road access, water, shade, parking, and post-eclipse traffic as part of the observation plan.
Sunset spectacle
The Balearics may offer clearer August skies and unforgettable low-Sun compositions, but totality is extremely close to the horizon. Terrain, haze, buildings, and even mountains blocking part of the corona can change the experience.
Best next step: Scout a clear west-northwest sea horizon and leave extra sky around the Sun, not just the solar disk.
Tiny totality zone
Portugal is part of the totality story, but only a restricted area near Parque Natural de Montesinho and Braganca is expected to see totality. Most of Portugal sees a deep partial eclipse.
Best next step: Verify your exact pin; a short drive can separate totality from a glasses-on partial event.
Still worth planning
Across Europe, northern Asia, northern and western Africa, much of North America, and parts of the Atlantic, Pacific, and Arctic, many viewers will see a dramatic partial eclipse. The UK, Ireland, France, North Africa, Canada, Alaska, and parts of the northern United States all have their own version of the day.
Best next step: Use certified viewers for the entire event and try projection for kids or groups.
Spain planning deep dive
The eclipse arrives near sunset. That low Sun is visually extraordinary — but also unforgiving. A hill, a tree line, a haze layer, or a traffic jam can ruin the view as surely as clouds.
Horizon first
Look west and west-northwest from your actual spot. In the Balearics and eastern Spain, the Sun is low enough that a coastal or elevated site with a clean sea horizon is worth a longer drive.
Weather has local character
Eclipse weather analyses favor the northern Meseta and Ebro Valley over the cloudier Cantabrian coast. But the final call is always the forecast in the 48 hours before eclipse day.
Traffic is part of the plan
Spanish authorities are preparing special traffic controls in several communities. Avoid same-day drives to famous viewpoints and check for official observation-site guidance closer to the date.
The corona extends several solar diameters beyond the disk. A mountain ridge can cut into the best part of totality even if the black disk itself is barely visible. Scout the exact line of sight — not just the town — and aim for a clear sea horizon.
Inside vs outside the path
A 99% partial eclipse is still a partial eclipse. Glasses stay on. The corona never appears. Understanding the difference changes how you plan.
Inside the path of totality
Outside the path of totality
The UK, Ireland, France, most of Portugal, North Africa, Canada, Alaska, and parts of the northern United States will see partial phases. Viewer demand in these regions will be high — order glasses well before the date.
Eye safety
The only moment you may remove viewers is during true totality, inside the path, while the Sun is fully covered. The moment any bright edge reappears, viewers go back on.
Use ISO 12312-2 eclipse glasses or handheld solar viewers whenever any bright part of the Sun is visible.
Outside the path of totality, there is no glasses-off moment, even at 99% coverage.
Inside totality, remove viewers only when the Sun is completely covered, then replace them as soon as bright sunlight returns.
Never use eclipse glasses with cameras, binoculars, telescopes, or other optics.
Optical filters must go on the front, Sun-facing aperture of the lens or telescope.
Supervise children, inspect viewers before use, and discard scratched, torn, or punctured filters.

Video explainer
This PhotoPills walkthrough covers how to pick a site, read the path, check local times, and understand horizon angles — everything you need before eclipse day.
Use the video as one input. Confirm your site with NASA GSFC, timeanddate, Xavier Jubier's interactive map, the Helioclipse 3D map, and local weather forecasts in the days before the eclipse.
Science notes
A total eclipse is not just a larger partial eclipse. For a few seconds to a few minutes, the Moon hides the photosphere and reveals structures that are normally overwhelmed by sunlight.
The Moon is slightly larger
The eclipse occurs about 2.2 to 2.3 days after lunar perigee, so the Moon's apparent disk is large enough to cover the Sun completely along the path.
Saros 126
The eclipse belongs to Saros 126, a long repeating family of eclipses. This is member 48 of 72, and all eclipses in the series occur at the Moon's descending node.
The corona
The corona is the Sun's outer atmosphere. It is faint compared with the photosphere, which is why it appears only during true totality or with specialized solar instruments.
Trip checklist
The best eclipse memories often come from boring preparation: maps saved, viewers counted, backup sites chosen, water packed, and everyone knowing the safety routine.

FAQ
Short answers for the decisions most readers need to make before they travel, buy viewers, or organize a group viewing.
The total solar eclipse occurs on Wednesday, August 12, 2026. The global event begins with partial phases at 15:34:15 UTC and ends at 19:57:57 UTC, but local times depend on your location.
Totality crosses remote Arctic regions, Greenland, Iceland, the North Atlantic, Spain, the Balearics, and a very small edge of Portugal near Braganca/Montesinho. Always verify an exact pin with an authoritative path map.
The maximum duration is about 2 minutes 18 seconds near greatest eclipse. Many accessible locations see less, such as around a minute in Reykjavik and roughly 1-2 minutes in parts of Spain depending on the exact site.
Spain is one of the most accessible places to see totality, with strong infrastructure and favorable August weather in some inland regions. The main challenge is that the Sun is low in the west, so terrain, buildings, haze, and horizon clearance matter.
Central Madrid and Barcelona are expected to see very deep partial eclipses, not true totality. A deep partial can be dramatic, but it does not reveal the corona and there is no safe glasses-off moment.
Yes. Western Iceland, including Reykjavik, Reykjanes, Snaefellsnes, and the Westfjords, lies in or near the totality path. Iceland has a higher Sun than Spain during totality, but weather mobility is crucial.
Only a restricted northeastern area near Parque Natural de Montesinho and Braganca is expected to see totality. Most of Portugal will see a partial eclipse, although some places will have very high obscuration.
Yes. Use ISO 12312-2 solar viewers for all partial phases. You may remove them only during true totality, only from inside the path, and only while the Sun's bright face is completely covered.
No. Eclipse glasses are for eyes only. Cameras, binoculars, telescopes, and long lenses need proper solar filters mounted on the front, Sun-facing aperture.
Watch the partial eclipse safely from your region if visible, host a projection activity, or use a trusted livestream from organizations such as timeanddate or the Exploratorium.
