South East England

Largely dry with sunny spells. Feeling cold. Rain arriving overnight.

  • Early coastal showers clearing away east to leave a mostly fine and dry day, with good spells of sunshine with light winds
  • Some clear spells early evening and turning chilly, before cloud increases from the west after dark
  • Feeling cold
  • Maximum Temperature 9C

Tonight:

  • Dry in the far east initially, before cloud and outbreaks of rain, locally heavy, moves east across all parts overnight
  • Potential for a spell of strong winds, perhaps coastal gales
  • Minimum Temperature 4C

Wednesday:

  • A cloudier day, with outbreaks of rain, locally heavy, spreading eastwards during the morning
  • Windy on coasts
  • Rain clearing in the afternoon
  • Briefly milder
  • Dry, clear skies and frosty overnight
  • Maximum Temperature 13C

Outlook for Thursday to Saturday:

  • A cold and frosty start on Thursday, otherwise, fine and dry with sunny spells
  • Similar conditions on Friday
  • Fine and dry with bright or sunny spells Saturday
  • Temperatures near normal

UK Day 6-7 and week 2

  • Mainly dry with some clear or sunny spells but rather cold towards the southeast at first as high pressure over the continent extends its influence here
  • Cloudier, windier and milder in the north and west with some outbreaks of rain
  • Early next week, it looks like the rain in the west will edge further east, bringing a short spell of rain to the east
  • High pressure may then re-assert itself close to or over the UK through early December
  • The largely dry, settled theme may be punctuated by brief unsettled spells though with areas of low pressure possibly crossing the UK, bringing some spells of wind and rain
  • Temperatures generally near average, but some overnight frost is likely, and rather cold by day where any fog persists

UK Week 3 and 4

  • The start of this period looks like being largely settled, with high pressure close to if not over the UK
  • However, as we move towards mid-December, there are signs that it will become less settled with west or northwesterly types preferred, These will bring some wetter and windier interludes with a risk of some snow, especially for hills in the north
  • These conditions may prevail into late December, although drier, more settled spells may also affect the UK at times, these probably more likely towards the south
  • Temperatures generally close to average through the period

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.
