Where Will the 2027 Eclipse Have the Longest Totality?

The longest calculated durations in this catalogue occur in Egypt. Among 219 totality pins, Red Monastery reaches 6m 23s at the site’s stored coordinates. That is a catalogue maximum, not a claim to have found the longest duration anywhere on Earth.

Why a few seconds may not decide your trip

Totality varies both across the width of the shadow and along its route. Approximate centre-line distance helps explain differences, but the contact-time calculation is the source of the duration shown. Inspect the actual viewing coordinate, especially near a path edge.

Small timing differences can be less useful than a clear view, reliable transport or an accessible site. The model uses a smooth lunar limb and the stated ΔT; it does not model lunar mountains or atmospheric refraction. Round-second comparisons should be read with those limits in mind.

Build Egypt favourites

Compare Luxor, Abydos and Dendera alongside other Egypt viewing locations. Use the weather and airport comparisons before choosing an itinerary.

Calculated astronomy uses NASA / Fred Espenak Besselian elements, a sea-level WGS84 observer and a smooth lunar limb. Historical weather is regional context, not a forecast. Airport routes, site access, travel advice and accommodation availability require current checks. Read the Sources & method.
