Wales

High pressure brings settled but widely cloudy conditions.

  • Overcast with a blanket of low cloud stretching across the mountains, bringing widespread mist and fog over the hills
  • The odd spot of rain in the north beneath the thickest cloud, though remaining dry for many with light winds
  • Minimum Temperature 9C

Saturday:

  • Hill fog lingers across the high ground, and elsewhere rather cloudy with the odd pocket of drizzle
  • The north and west will be best placed to catch occasional brighter breaks
  • Maximum Temperature 14C

Outlook for Sunday to Tuesday:

  • High pressure continues to bring settled conditions
  • Mainly cloudy with the occasional spot of rain interspersed with brighter interludes as well
  • Light winds but getting slightly breezier on Tuesday

UK Day 6-7 and week 2

  • High pressure is likely to dominate the weather across many parts of the UK during this period, bringing plenty of dry and settled weather for most, although it may be fairly cloudy at times
  • Where skies clear overnight some areas of fog, and perhaps frost, may develop
  • Southern and eastern areas are expected to be mainly dry through much of this period, while any more unsettled conditions and periods of rain are more likely to affect areas further north, particularly the north and northwest of Scotland and Northern Ireland
  • Winds will often be light in the south, but there could be some spells of strong winds across the north and west
  • Temperatures will probably be close to or warmer than normal overall, although some cold nights are possible at times

UK Week 3 and 4

  • After a settled start to November, beyond mid-month there will probably be a change towards more unsettled conditions for a time
  • This means an increased chance of periods of wet and windy weather for parts of the UK, perhaps more so in central and southern areas
  • 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 or above average overall, although some colder interludes are possible, especially in the north

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
