Rowlands Castle Circular Walk

A walk, first through park- and woodland, then through some remote westerly valleys of the South Downs. At its best in spring for plentiful bluebells and wild garlic.

UK Day 6-7 and week 2

  • Cold or very cold conditions are likely to affect most if not all parts of the UK early in this period, with wintry showers affecting in particular northern parts and exposed coastal districts
  • Overnight frost will likely be widespread and occasionally strong winds will result in significant wind chill
  • However, there may be some more organised areas of rain and snow, accompanied by strong winds, which run across some parts
  • This could lead to some disruptive weather at times

  • However
  • there is a chance of more changeable weather patterns at times, which would see Atlantic weather systems periodically move across the country
  • These will bring some wetter and windier interludes with a risk of some snow, especially for hills in the north
  • Temperatures generally close to average, perhaps a little above at times, especially in the south

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!

West Sussex weather (Accuweather)

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