South East England

Dry with sunny spells on Wednesday. Lighter winds.

  • Cloudy with occasional showers continuing overnight in Kent and Sussex
  • Drier with clear spells elsewhere, potentially with some fog patches developing
  • Brisk winds will gradually ease
  • Minimum Temperature 4C

Wednesday:

  • Any fog patches slowly clearing during the morning, with residual isolated showers in Kent and Sussex dying away
  • Otherwise, dry with sunny spells and winds generally lighter than on Tuesday
  • Maximum Temperature 12C

Outlook for Thursday to Saturday:

  • Largely dry with a mixture of cloud and sunny spells, perhaps with some overnight fog patches and patchy drizzle
  • Rain arriving later on Saturday
  • Chilly at times

UK Day 6-7 and week 2

  • Turning more unsettled and significantly colder as we head into the weekend with rain or showers for most regions, The heaviest and most frequent spells of rain are most likely in the north where they are likely to turn wintry, especially to the hills of Scotland, but perhaps also to lower levels in the far north as colder air digs south
  • The chance of any widespread or disruptive snowfall affecting more populated areas at this stage however remains low
  • Less certainty for the south but even here there is a chance of some more organised rain, and potentially some hill snow
  • Often windy, with a chance of gales at times, especially in the north and east
  • Temperatures falling below average and feeling particularly cold in the strong winds

UK Week 3 and 4

  • Signals vary in prevailing weather patterns through this period but likely more unsettled and colder than during early November for the start of the period
  • There is a greater chance of more mobile weather patterns which would see Atlantic systems periodically move across the country
  • These bringing some wetter and windier interludes followed by drier periods and with the colder air in situ a greater risk of some snow, especially for hills of the north
  • A trend toward less mobile weather or more settled conditions is favoured into December, although some wetter and windier interludes remain likely at times
  • Temperatures also trending closer to average, especially in the south

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.
