How to compare eclipse destinations
Start with eclipse type and totality duration. Then check path margin and Sun altitude. After the astronomy, compare durable practical factors such as accessibility, accommodation depth and your ability to relocate if later forecasts favor another part of the path.
Why some comparisons show a score out of 70
The full Eclipse Viewing Score uses 100 points. Seventy points come from astronomy and durable planning factors: totality duration (25), path margin (8), Sun altitude (7), accessibility (12), accommodation (8), relocation flexibility (5) and viewing environment (5).
Historical sky conditions account for 25 points and heat comfort for 5. When verified historical climate data is unavailable for a location, those 30 points remain visibly unscored rather than being estimated.
What the score cannot know
A structural score is not a live travel forecast. It does not know future hotel availability, traffic, border queues, ferry disruption, temporary road closures or eclipse-day clouds. Those conditions should be checked close to travel and kept separate from stable astronomical geometry.
Useful comparison sets
- Málaga vs Gibraltar vs Tarifa: convenience against deeper western-path totality.
- Gibraltar vs Tangier: two sides of the Strait with different transport and relocation options.
- Luxor vs Jeddah: extreme totality duration against very strong gateway access.
- Oran vs Sfax vs Luxor: how the North African path changes as it moves east.
Do not treat the highest score as a command
The score is a decision aid. You may value totality duration more than lodging, or easy access more than a few extra seconds. The components remain visible so you can make that trade-off yourself.
What to calculate next
If you already know your base location, use Totality Gain to measure whether moving is worthwhile. If your base is partial, use Totality Finder first.
