Astronomy calculations are location-specific
Eclipse circumstances are calculated for a coordinate, not for an entire city. Published city pages use a reference coordinate so comparisons remain consistent. Your exact observing site can produce different contact times, central-phase duration, Sun altitude and path margin.
Use Eclipse Finder for the actual observing coordinate before relying on a city-level result.
Path boundaries have uncertainty
The mathematical edge of a solar-eclipse path should not be treated as a physical guarantee. Lunar limb topography, model choices and the observer's actual position can affect edge circumstances. Eclipse Wayfinder therefore uses an inside-path planning buffer in the Totality Finder instead of encouraging observation from the calculated limit.
NASA eclipse material is an important reference for event geometry. See the NASA GSFC eclipse site and our data-sources page.
Historical climate is not a weather forecast
NASA POWER climatology describes long-term regional conditions. The solar clarity proxy, mean temperature and humidity values help compare destinations on a common historical basis. They do not predict whether clouds will cover the Sun on eclipse day.
Short-range weather forecasts become useful much closer to an eclipse and can change the best practical observing location.
Travel information changes
Access rules, border requirements, visas, security conditions, road closures, ferries, flights, room availability, prices and local restrictions can change. Practical scores on Eclipse Wayfinder are structural planning aids, not live travel advice. Check current official information before booking or travelling.
Solar viewing requires proper safety equipment
Looking directly at the Sun can injure your eyes. During partial and annular phases, use proper solar viewers or an appropriate indirect method. Optical equipment such as cameras, binoculars and telescopes requires suitable front-mounted solar filtration. During a total eclipse, unfiltered viewing is limited to the brief total phase when the bright solar photosphere is completely covered.
Read the Eclipse Wayfinder safety guide and the current American Astronomical Society eye-safety guidance.
Commercial travel pages are comparison guides
Pages about tours and cruises explain questions to ask and factors to compare. Unless a page clearly states otherwise, Eclipse Wayfinder does not certify an operator, guarantee an itinerary, or promise that a particular commercial product will deliver an eclipse view.
