How to prepare for the 2026 total solar eclipse

A well-prepared total eclipse is the difference between a lifelong memory and an avoidable disappointment. This guide covers everything you need to do before August 12, 2026.

Equipment checklist

Essential

  • Eclipse glasses certified ISO 12312-2 and CE (check for the mark inside the frame) — buy well in advance; they sell out weeks before
  • Accurate time app on your phone synced with GPS (important for not missing C2/C3)

Highly recommended

  • Binoculars or small telescope with solar filter (for the partial phase)
  • DSLR or mirrorless camera with ≥ 400 mm telephoto + solar filter for photography
  • Sturdy tripod
  • Blanket or folding chair
  • Water bottle and sunscreen (August is hot)

Logistical planning

6–12 months ahead (now)

  • Choose your location: use this calculator to verify the terrain horizon at your exact spot
  • Book accommodation: hotels in the totality path (Basque Country, Aragon, Valencia) sell out months in advance for astronomical events of this scale
  • Plan entry and exit routes: heavy traffic is expected

1–2 weeks before

  • Check the cloud forecast on this site (available from July 27, 2026)
  • Have a Plan B within 200 km: a 1–2 hour drive can be the difference between overcast and clear
  • Practice with your camera: learn to remove the filter quickly at C2

The day before

  • Review the final cloud forecast and decide whether to change location
  • Charge all devices
  • Confirm the exact C2 time for your point (use the calculator)

Useful apps

  • Eclipse2026.app (this site) — terrain horizon + cloud forecast
  • SkySafari or Stellarium — sky visualization before and during
  • Time.is — exact time synchronization

On eclipse day

  1. Arrive at your observation point at least 2 hours early — traffic near the path will be intense
  2. Set up your equipment and find the correct orientation (the Sun will be to the west-northwest)
  3. Watch the partial phase with glasses; use the time to settle into your rhythm
  4. At C2, remove your glasses and look freely — only during totality
  5. When the horizon brightens again (C3 approaching), put your glasses back on

Safety

Never look directly at the Sun outside the seconds of totality without certified protection. The consequences are permanent retinal burns. Totality is the only safe moment to look without a filter.


And after 2026: 2027 and 2028

Spain is living through an unusual trio of solar eclipses in just three years. If you miss the 2026 one, you still have two more chances — but neither replaces the August 12 totality:

  • Total eclipse, August 2, 2027 — the path of totality crosses southern Spain (Cádiz, Málaga, Granada, Almería) with over 4 minutes of totality, nearly double that of 2026. It is the longest eclipse of the 21st century over Spanish soil. The Sun will be high, near solar noon, with none of the horizon issues of 2026.
  • Annular eclipse, January 26, 2028 — the annular path crosses central and eastern Spain (Galicia, Castilla y León, Madrid, Valencian Community). Annular, not total: the Moon leaves a "ring of fire" around the Sun. No corona and you must keep your glasses on, but the sight is spectacular and many large cities fall inside the path.

Quick comparison:

| | Aug 12, 2026 (total) | Aug 2, 2027 (total) | Jan 26, 2028 (annular) | |---|---|---|---| | Max duration | ~2 min | ~6 min | ~5 min ("ring") | | Zone in Spain | North (Galicia → Balearics) | South (Andalusia) | Centre-east (Galicia → Levante) | | Local time | Sunset | Noon | Afternoon | | Main challenge | Western horizon | Heat + crowds | Remembering NOT to take glasses off |

2026 is unique because of its sunset light during totality: a combination of solar corona and golden twilight that won't repeat in the other two. Even if you also chase 2027 and 2028, this one is worth it on its own.

If you plan to see all three: the "Eclipse Pass" on eclipses.app gives you access to all three editions of the calculator.

⚠️ Las gafas de sol normales NO son seguras para observar un eclipse. Solo productos con certificación ISO 12312-2 protegen tu vista. NUNCA mires al Sol con cámara, prismáticos o telescopio sin filtro solar específico — el daño ocular es permanente e instantáneo.
