Visibility in km. Above 50km is 'good'. Humidity and air pollution make it worse. Theoretical maximum is 300km/200 miles in clean dry polar air.

On the South Downs, at ~ 170m/500ft, the horizon is is ~ 45km/30 miles away. On a mountain at 1,000m/3,000ft, it is ~ 160km/100 miles away. Formula: horizon in km = √ (13 x altitude in m)

Notes

  • The percentage of the moon which is illuminated doesn't vary much with location.
  • A full moon is not just bigger, it is much brighter. A quarter moon (1/2 disk visible) give less than 5% of the illumination of a full moon. You can walk with a quarter moon if its high in the sky (after dusk for a growing moon, before dawn for a shrinking moon).
  • Sky glow (light reflected by air or clouds) from nearby cities, and especially snow on the ground also effect light levels.
  • Times will vary a few minutes, as (i) these figures are for the centre of the county the walk is in, (ii) if there are hills on the horizon, and (iii) if you are on a hill
  • Of course, you need a cloudless night as well!

Now would be a good time for a cup of tea.
