Cosmo Clock 21

You can see 161 km from here, looking north.

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 161 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.

79out 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 December to January.

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.
