Project Greenland / Spain 2026
Total Solar Eclipse Observation Sites
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/
​
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 prospects for a sunny sky in Spain are very good along the complete length of the track, however the sun will be low in the sky close to sunset, therefore you will need a clear sightline through the atmosphere to the horizon. The sun will set in eclipse from our observation sites at Siguenza Castle, Spain and be extremely low on the horizon on the North Atlantic Coast.
Greenland Site Data
Scoresby Sound fjord, an inland sea of vast icebergs on Greenland’s east coast sits directly on the centreline of the eclipse track where our first group will be waiting to observe this event.

San Pedro de la Ribera, Spain Site Data
The shadow of the total solar eclipse of 12 August 2026 will then cross the Atlantic Ocean until it reaches the Bay of Biscay on Spain’s northern coast late in the afternoon and our second observation site will be on the cliff tops of this rugged coast.

Siguenza, Spain Site Data
The dry central regions of Spain offer very promising prospects of a clear sky and a sunset eclipse. Our third observing location will be in this region, observing from the ramparts of a magnificent castle.​
