Interactive map of the August 12, 2026 total solar eclipse
Explore the total solar eclipse of August 12, 2026 across Spain. Click any point on the map and check whether the Sun will be above the terrain horizon at the key moment, with a 0–100 score.
A heatmap layer colors the whole territory by eclipse visibility, accounting for the real terrain, not just geometry.
How it works
- Click a point or search a location to see the verdict and visibility score.
- Toggle the heatmap layer to see at a glance which areas have a clear horizon.
- Jump to curated cities and viewpoints for their full eclipse details.
Why terrain matters
The eclipse is at dusk, with the Sun very low. A mountain to the west-northwest can hide the Sun even where geometry says it’s visible. The map samples the terrain horizon (DEM elevation model) along the Sun’s azimuth, not a flat theoretical horizon.
Frequently asked questions
What does the heatmap show?
Eclipse visibility accounting for the terrain horizon. Green means the Sun is clear; red means the terrain hides it at the evaluated contact.
Can I check my exact location?
Yes. Click any point on the map and the calculation runs for those coordinates, using the real terrain elevation.
