Project Greenland / Spain 2026 

A clear sky is the prime requirement for observing a total solar eclipse, but as weather forecasts are not possible months or years in advance, we must rely on data from the same period in previous years when selecting an observation site. The acknowledged expert in predicting weather prospects for eclipse tracks is Jay Anderson and you can see his work on https://eclipsophile.com/tse2026/  

​

​Climate projections are estimates made by experts based on data collected over a period of time but they are, of course, just projections. On eclipse day it is the weather that matters and that will remain unknown until the day dawns.

Greenland

The 2026 eclipse track starts across Eastern Siberia and the North Pole, which are both likely to be overcast. The coastal area of Greenland is also a cloudy location, however the massive Greenland icecap acts as a barrier to weather fronts approaching from the Atlantic. Our advance survey of August weather in Scoresby Sound in August 2022 confirmed that the local climate below the high peaks in the inner fjords is consistent with Jay Anderson’s projections.  Added to this, the sun will also be higher in the sky from Greenland than the other observation sites in Spain.

The sun will be low in the sky close to sunset, therefore you will need a clear sightline through the atmosphere to the horizon.  A view of an eclipsed sun near sunset across the North Atlantic ocean will be a quite spectacular sight, however any eclipse observation does depend on a clear sky at the time of the eclipse.  The map below predicts a higher average amount of cloud is normal along the Atlantic Coast than would be expected further inland at our Siguenza Castle and Gormaz Castle sites.
