Wales

Colder on Monday but mostly sunny, wintry showers by mid-week.

  • Some cloud this evening but clear periods developing and skies widely clearing overnight, away from the far west
  • Turning cold with a slight frost developing in places, mainly in the countryside and a risk of some localised icy patches
  • Minimum Temperature 0C

Monday:

  • A dry and sunny day to come for most of Wales but Anglesey and Gwynedd may be somewhat cloudier at times
  • Feeling chilly despite the sunshine and light northerly breeze
  • Maximum Temperature 7C

Day 3-5 : Outlook for Tuesday to Thursday:

  • Rain or showers on Tuesday
  • Heavy wintry showers and sunny spells on Wednesday and Thursday with snow in places
  • Often windy and feeling much colder
  • Ice and frost likely overnight

UK Day 6-7 and week 2

  • A widespread and in places sharp frost to begin Friday
  • Then a transition during the day to less cold and more generally unsettled conditions as Atlantic weather fronts make inroads into the UK
  • These will bring spells of rain potentially quite widely, though the wettest conditions through the latter part of November may occur across more southern areas
  • There is also the potential for some windy weather to develop at times, again this perhaps more likely further to the south
  • Compared to the preceding few days, a reduced likelihood of snowfall, though some upland snow remains possible in the north
  • Temperatures probably returning closer to average, generally speaking, for late November, and perhaps becoming mild at times in the south

UK Week 3 and 4

  • Whilst there is a lot of uncertainty as to the flavour of weather affecting the UK into December, there is a greater chance than normal of slower evolving weather patterns
  • A mixture of weather types seems most likely and so some wetter days, with widespread rain or showers and the chance of snow, mainly for higher ground in the north
  • Equally some drier periods are also anticipated, increasing the possibility of some frosty nights and fog
  • Overall, temperatures close to average are most likely, but some colder spells are also possible, especially if any prolonged settled spells develop

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

  • Max Height (solar noon) is when the sun is highest in the sky.
  • Day length is dawn to dusk as there is enough light for walking for at least 30 minutes before sunrise and after sunset, even on an overcast day.
  • At 'Light' (nautical dawn) the horizon becomes visible. At 'Dawn' (civil dawn) there is enough light to read, and drivers can switch their lights off. Finally the sun rises.
  • After sunset, there is still enough light to read until 'Dusk' (civil dusk) or lighting up time for drivers. The horizon is still visible until 'Dark' (nautical dusk).
  • Times will vary if there is a hill on the horizon.

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
  • Sunlight is ~ 1,000,000 times brighter than moonlight.
  • Of course, you need a cloudless night as well!
