Wales

Turning more unsettled than of late.

  • Outbreaks of rain spreading more widely across the country, heavy at times
  • Winds easing and cloud lowering, thus turning murky in places
  • Mild, with some locations remaining in double digits
  • Minimum Temperature 9C

Saturday:

  • Low cloud lifting to allow some bright spells
  • Showers developing during the day, locally heavy and perhaps thundery
  • Light winds
  • Less warm than Friday but temperatures still above average
  • Maximum Temperature 15C

Outlook for Sunday to Tuesday:

  • Further showers and rain possible on Sunday, though generally lighter than Saturday
  • Becoming mainly dry into next week with bright spells and light winds
  • Temperatures returning to the seasonal norm

UK Day 6-7 and week 2

  • The final week of March into the start of April looks to be characterised by a slowly evolving, but changeable weather pattern
  • Initially, a dry interlude is likely with spells of sunshine across many areas
  • With time, these drier conditions will become more favoured across the south
  • Further north and northwest, there is a greater chance of rain or showers at times, these accompanied by windier spells and a chance of gales for parts of the far northwest
  • There is a small chance that these wetter, more unsettled conditions could become more widespread for a time
  • Temperatures will probably pan out close to average overall, though chilly nights remain possible where clear skies coincide with light winds

UK Week 3 and 4

  • Confidence is lower than normal, but blocked or slow-moving weather patterns are most probable through the middle of April
  • This can lead to slow-moving areas of low and high pressure and, depending on their location, this can result in periods of either dry conditions or wetter episodes with rain or showers
  • Temperatures will vary, with some large day-to-day swings possible, but overall are likely to be near average

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!

Now would be a good time for a cup of tea.
