Portland Observatory

You can see 112 km from here, looking north-west.

Calculating the panorama…

Drag to turn around. The relief is drawn 2.2 times taller so the ridges can be read; far ridges are paler, as in the real air.

The view

Up to 112 km away.

Calculated on the relief one degree at a time, up to 250 km, with the curvature of the Earth and the refraction of the air: what stands above the horizon from here.

81out of 100

Our own rating, from the relief and the climate only: open horizon (35 points), how far you see (25), sea and named peaks in view (20) and clear months (20).

From the relief only: buildings, trees and haze are not in the model. On a hazy day you see much less; 250 km is the limit of our calculation.

The sun

The best sunsets are from August to September.

When the sun really disappears from this viewpoint — behind the relief or into the sea — and in which direction, on the 15th of each month, in local time.

  • Time: when the sun goes behind the horizon you see from here.
  • Minutes: how much earlier the relief hides the sun.
  • %: share of clear sky that month (NASA, 2001–2020).

The highlighted months are the clearest. Golden hour starts about an hour before.
