The August 12 Solar Eclipse: Where It’s Visible and How to Watch Safely

Quick summary

A total solar eclipse will cross parts of Greenland, Iceland, northern Russia, Spain, and a small corner of northwestern Portugal on August 12, 2026. Many other places—including most of Canada, parts of the northern United States, much of Europe, and northwestern Africa—will see a partial eclipse instead. Some locations will not see the eclipse at all.

Before making plans, check your exact location on an authoritative eclipse map or city table. Being in a country named in the forecast does not necessarily put you in the narrow path of totality. A 99% partial eclipse is still not totality, and the eye-safety rule remains different: during every partial phase, use safe eclipse glasses or a handheld solar viewer that meets the ISO 12312-2 standard, or use an indirect method such as pinhole projection. Ordinary sunglasses are not safe.

Travel may be worthwhile if experiencing totality is your main goal and you can reach the path with flexible, affordable arrangements. It is less compelling if your destination offers only a partial view, the western horizon is blocked, or weather and transport risks would make the trip stressful. If the eclipse is not visible where you are, NASA plans to begin a live broadcast at 1:15 p.m. EDT.

First determine which eclipse you can actually see

The phrase “August 12 eclipse” describes one astronomical event, but the experience changes sharply by location. There are three practical outcomes.

You are inside the path of totality

The Moon will completely cover the Sun’s bright face for a brief period. NASA’s path crosses Greenland, Iceland, northern Russia, the Atlantic Ocean, Spain, and a small corner of Portugal. Totality generally lasts less than two minutes for most people in the path and remains under two and a half minutes even near the center.

Only during the brief period when the Sun’s bright face is completely covered may viewers look directly without solar eye protection. Eclipse glasses must be used during the partial phases before totality and put back on as soon as any bright part of the Sun reappears.

You are outside the path but inside the partial-eclipse area

The Moon will cover only part of the Sun. This applies to most viewers in Canada, the northern United States, Europe, and northwestern Africa. There is no safe glasses-off moment. Proper eye protection is required every time you look directly at the Sun.

The amount covered varies enormously. NASA’s selected-city table lists about 6% coverage for Edmonton, 9% for New York, 18% for Montreal, 91% for London, 95% for Lisbon, and 99% for Madrid and Barcelona. These examples show why a continent-level forecast is not enough. A small partial eclipse in North America and a near-total partial eclipse in Europe are both “partial,” but they will not look equally dramatic.

The eclipse is below your horizon or outside your area

You will not see the event directly. That is not a reason to improvise unsafe viewing or make a last-minute trip. NASA’s live broadcast is a practical alternative, especially for families, classrooms, and viewers facing clouds or blocked horizons.

Use NASA’s eclipse map and local-time tables as the first check. If your city is not listed, use a reputable location-specific calculator and confirm that its times are local. Do not copy a time from another city, even within the same country.

Totality and 99% coverage are not interchangeable

The most important travel distinction is not “some eclipse versus no eclipse.” It is totality versus partiality.

Inside the totality path, the Sun’s bright surface is completely hidden for a short interval. Outside that path, even if 99% is covered, a bright portion remains. The sky and surroundings may change noticeably during a deep partial eclipse, but the Sun is never fully covered and direct viewing still requires protection.

This matters for both expectations and safety. A traveler who assumes that “almost total” means essentially the same experience may pay for flights and lodging without receiving the phenomenon they expected. A viewer who assumes that 99% coverage creates a safe moment may expose their eyes to the remaining bright Sun.

If totality is the reason for your trip, verify that the exact accommodation or viewing site—not merely the nearest famous city—is inside the path. The path has boundaries. A short drive can sometimes change the experience, but congestion, road closures, parking rules, and terrain can make that drive unreliable on eclipse day.

What selected cities can expect

NASA’s July 30 update provides the following local-time examples. They are planning references, not substitutes for checking your exact coordinates and local conditions.

In parts of mainland Europe and Africa, the Sun will be low in the west and may set before the partial phase ends. A mathematically visible eclipse can therefore be practically invisible from a site behind buildings, trees, hills, or mountains. For Spain in particular, a clear western horizon is part of the viewing plan, not a minor preference.

Should you travel for it?

There is no universal answer. The decision depends on what experience you want, what you would spend, and how much uncertainty you can accept.

Travel is easier to justify when:

• seeing totality is a meaningful personal goal;
• the exact viewing site is confirmed inside the totality path;
• the site has an unobstructed view in the Sun’s direction;
• transportation and lodging can be changed or canceled;
• you have a backup site reachable without assuming empty roads; and
• the trip would still have value if clouds block the eclipse.

Staying local or watching the broadcast may be wiser when:

• your destination is outside the totality path despite aggressive marketing;
• the trip would require expensive, nonrefundable bookings;
• you are relying on a same-day long drive through likely congestion;
• mobility, heat, crowding, or medical needs would make the site unsuitable;
• the western horizon is obstructed; or
• you would regard a cloudy sky as a complete loss.

Weather forecasts become more useful close to the event, but no forecast can guarantee a clear view. Avoid moving repeatedly between distant sites based on every forecast update. A practical plan is to choose one primary site and one realistic backup, set a decision deadline, and keep essential reservations flexible.

Travelers should also check local authority and venue information for access hours, parking, public transportation, crowd controls, fire restrictions, and permitted equipment. A location shown on an eclipse map is not automatically open to the public.

The non-negotiable eye-safety rules

Solar-eclipse viewing is safe when the correct method is used. The danger comes from treating ordinary products or improvised filters as adequate.

For direct viewing during any partial phase

Use eclipse glasses or a handheld solar viewer intended for direct solar observation and conforming to ISO 12312-2. Regular sunglasses are not a substitute, regardless of how dark they appear. NASA does not approve individual brands.

The American Astronomical Society warns that an ISO statement printed on a product is not proof by itself. Buy from a supplier whose products have been properly tested and whose identity and authorized sellers can be verified. Inspect viewers before use. Discard them if the filter is torn, scratched, punctured, loose, or otherwise damaged.

Put the viewer in place before looking toward the Sun, and turn away before removing it. Adults should supervise children and confirm that the viewer stays over their eyes. Anyone unable to use a viewer reliably should use an indirect method instead.

For cameras, binoculars, and telescopes

Do not look through magnifying optics while wearing eclipse glasses. A camera lens, telescope, or binoculars concentrate sunlight and require a special-purpose solar filter secured to the front, or Sun-facing end, of the equipment. An eyepiece filter or eclipse glasses behind the optics are not a safe substitute.

Seek advice from an experienced astronomer or equipment specialist before using an optical solar filter. If you are uncertain about the filter or its installation, do not point the device at the Sun. Photographing the event is optional; protecting your eyesight and equipment is not.

During totality

Only viewers located inside the totality path may remove solar protection, and only after the Sun’s bright face is completely covered. Replace protection immediately when the bright Sun begins to reappear. If you are unsure whether totality has begun or ended, keep the viewer on.

Everyone watching a partial eclipse—including people just outside the totality boundary—must keep proper protection in use for every direct view.

Safe viewing without eclipse glasses

Indirect projection lets you observe the changing shape of the Sun without looking at it. A simple pinhole projector can be made from card or a box. Stand with your back to the Sun and allow light through a small hole onto a white surface. Watch the projected image, not the Sun and not through the hole.

Everyday objects can also form projections. The small openings in a colander or between leaves can cast multiple crescent-shaped images during the partial phase. This can be especially useful for groups because several people can watch the projection without sharing a face-worn viewer.

Do not use a mirror, smoked glass, exposed film, CDs, phone screen, stacked sunglasses, or homemade tinted material as a direct-view filter. If verified viewing equipment is unavailable, projection or NASA’s broadcast is the safer choice.

A practical plan for families and groups

Organizers should treat eye safety as a procedure, not simply hand out glasses.

1. Confirm visibility and local time. Record partial start, maximum, totality if applicable, and end or sunset.
2. Choose the viewing site. Check the Sun’s direction, horizon, shade, toilets, accessibility, and local access rules.
3. Verify equipment early. Trace viewers to a reputable supplier, inspect every unit, and bring extras.
4. Assign supervision. Adults should demonstrate putting viewers on before turning toward the Sun and looking away before removing them.
5. Separate optical equipment. Keep unfiltered cameras, binoculars, and telescopes away from the viewing area unless a knowledgeable operator has fitted the correct front-mounted filters.
6. Prepare for ordinary outdoor risks. Bring water, weather-appropriate clothing, sunscreen, hats, and any needed medication. The partial phases can last well over an hour.
7. Set a cloud plan. Decide whether the group will wait, move to a nearby backup, or watch the broadcast.

Children do not need to miss the event because direct viewing is difficult. Projection activities can make the changing solar shape visible while reducing the chance that a child lifts or misuses glasses.

What to check again before August 12

This article is based on NASA information available on August 5. Before leaving home or committing to travel, recheck:

• your exact local start, maximum, and end times;
• whether the site is inside or outside the totality path;
• the direction and height of the Sun at maximum eclipse;
• the latest cloud, heat, wind, wildfire-smoke, and severe-weather outlook;
• road, transit, parking, park, beach, or venue restrictions;
• the condition and source of all viewing equipment; and
• NASA’s broadcast schedule if remote viewing is your backup.

The geometry of the eclipse is predictable, but weather, access, and event operations can change. Those update-sensitive facts should determine the final plan.

The bottom line

Start with location, not excitement. Verify whether your exact site will experience totality, a partial eclipse, or no visible eclipse. If you travel, pay for the experience only after confirming the path, horizon, access, and a flexible weather plan.

For safety, the simplest rule is even clearer: if any part of the bright Sun is visible, use a verified solar viewer or an indirect projection method. Ordinary sunglasses are never enough, and magnifying optics need their own front-mounted solar filters. When location or weather does not cooperate, NASA’s live broadcast offers a safe way to share the event without forcing an expensive or risky plan.

FAQ

Where will the August 12, 2026 eclipse be total?

NASA says the path of totality crosses Greenland, Iceland, northern Russia, the Atlantic Ocean, Spain, and a small corner of northwestern Portugal. Exact coordinates still matter because only locations inside the narrow path experience totality.

Can I see the eclipse from the United States or Canada?

Many northern U.S. and Canadian locations will see a partial eclipse, but coverage varies greatly and some places will see little or none. Check a location-specific map and local times rather than relying on a national forecast.

Is a 99% partial eclipse basically totality?

No. A bright portion of the Sun remains visible, so there is no safe glasses-off period. The visual experience also differs from the brief complete coverage inside the totality path.

Are ordinary sunglasses safe if I wear two pairs?

No. Ordinary sunglasses, even very dark or stacked pairs, are not designed for direct solar viewing. Use a safe solar viewer conforming to ISO 12312-2 or an indirect projection method.

Can I photograph the eclipse through eclipse glasses?

Do not place eclipse glasses behind a camera, telescope, or binoculars. Magnifying optics require a special-purpose solar filter secured over the front of the lens or aperture. Seek expert guidance for the exact equipment.

Can children watch safely?

Yes, with close adult supervision and properly fitting viewers. Indirect projection is a useful alternative for children who may not keep a viewer correctly positioned.

What if it is cloudy or the eclipse is not visible where I live?

NASA plans to stream the eclipse beginning at 1:15 p.m. EDT on August 12. Confirm the live schedule shortly before the event because programming details can change.
