Wales

Cloudy with patchy rain. Turning drier and colder by dawn.

  • A mostly cloudy evening with patchy outbreaks of rain
  • Turning drier overnight with some clear spells developing by dawn as winds ease
  • A continued risk of coastal showers
  • Feeling chillier than recent nights
  • Minimum Temperature 3C

Thursday:

  • A fine and largely dry day with a good number of sunny spells
  • Chance of showers along western coasts
  • Noticeably colder with temperatures dropping below the seasonal average
  • Maximum Temperature 13C

Outlook for Friday to Sunday:

  • A dry end to the week with sunny spells and light winds is most likely, though occasional showers are possible
  • Rather cold with rural frost and fog patches at night

UK Day 6-7 and week 2

  • Much of this period will be dominated by high pressure to the east of the UK, and areas of low pressure over the Atlantic
  • Bands of cloud and rain will attempt to push eastwards at times, but possibly weakening as they do so
  • As such, there may be some reasonable dry weather during the early part of next week, with any significant rain most likely western areas
  • However, from midweek onwards it is possible low pressure may become increasingly influential, with an increased chance of rain, showers and perhaps strong winds, especially in the west or northwest
  • With winds often from a southerly direction, temperatures will likely trend above average, with some warm conditions possible at times
  • Towards the end of the period high pressure may become more influential

UK Week 3 and 4

  • Potentially some wet and windy weather at first, especially in the northwest, but a trend towards more settled conditions is most favoured for late October as high pressure becomes increasingly dominant
  • This would bring the potential for frost and fog at night, and possibly large variations between daytime and overnight temperatures
  • Into early November, high pressure may become more centred to the northwest of the UK, resulting in a gradual trend towards more unsettled conditions

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!
