Wales

Cloudy, though feeling warm in any sunny spells.

  • Early morning mist and fog soon lifting to leave a dry and settled day
  • Some sunny spells developing at times, particularly across the northwest, and feeling warm in the sunshine, but remaining cloudy for many with light winds
  • Maximum Temperature 15C

Tonight:

  • Remaining settled tonight
  • Widely cloudy, with low cloud lingering across the high ground, although skies clearing at times, allowing patchy fog to form in places due to light winds
  • Minimum Temperature 7C

Thursday:

  • Another cloudy day, with occasional spots of light rain affecting the north at times
  • Some sunny spells further south, though becoming increasingly cloudy through the day
  • Winds remaining light
  • Maximum Temperature 14C

Outlook for Friday to Sunday:

  • Remaining settled as high pressure sits across the UK
  • Often cloudy, with occasional spots of light rain, though some sunny spells too
  • Overnight, patchy fog is possible under clearer skies

UK Day 6-7 and week 2

  • High pressure is likely to dominate the weather across many parts of the UK during this period
  • This will mean plenty of dry and settled weather through to the middle of November
  • Where skies clear overnight some areas of fog and frost are likely to develop
  • Southern areas are expected to be mainly dry during this period
  • Any more unsettled conditions and periods of rain are more likely to affect areas further north, particularly the far north and northwest of Scotland
  • Winds will likely be light in the south, but there could be some spells of strong winds across the north
  • Temperatures will probably be close to normal overall, although some cold nights are possible at times

UK Week 3 and 4

  • After a relatively settled start to November, around mid-month there will probably be a change toward more unsettled conditions for a time
  • This means an increased risk of periods of wet and windy weather for parts of the UK, perhaps more so in the south
  • However, there is low confidence whether unsettled, wetter weather or drier and more settled conditions will dominate by the end of the month
  • Temperatures will probably be close to average overall, although some colder interludes are possible

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
