Terrain and weather odds in Constantine
At maximum eclipse the sun stands 51° high toward the ESE (108°). The measured terrain horizon in that direction, seen from the city centre, is 7.9°. The sun clears it by 43.2°, so terrain will not hide the eclipse maximum from the centre of Constantine.
Around 10:00 local time, the hour of maximum eclipse, 85% of hours between 30 July and 5 August had clear skies (cloud cover of 20% or less) across 20 years of ERA5 reanalysis, 2005 to 2024. These are historical odds, not a forecast.
