Wales

Dry and warmer on Thursday with plenty of sunshine.

  • Staying dry this evening and overnight with light winds and often clear skies
  • Not as cold as last night but still chilly with a slight patchy frost in some rural areas
  • Isolated mist or fog patches forming
  • Minimum Temperature 1C

Thursday:

  • Any mist soon clearing, then a dry and mostly sunny day
  • High level cloud may give a hazier sky at times
  • Feeling warm in the spring sunshine with light winds
  • Maximum Temperature 19C

Outlook for Friday to Sunday:

  • Spells of warm hazy sunshine on Friday but rain possible later, locally heavy
  • Cloudier over the weekend with showers likely at times, but some dry weather too
  • Feeling somewhat cooler

UK Day 6-7 and week 2

  • Still rather unsettled across much of the UK at first with scope for some heavy showers across parts of the south on Sunday, but overall, the final week or so of March to the start of April looks to be characterised by a slowly evolving, generally changeable weather pattern
  • This means some drier interludes are likely, perhaps more especially in the south, where overnight fog is also a possibility
  • Further north and northwest, there is a greater chance of rain or showers, these accompanied by windier conditions at times
  • There is a small chance that these wetter, windier conditions may 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 for the first half of April
  • This can lead to slow-moving areas of low and high pressure and, depending on their location, this can result in extended periods of either dry conditions (slightly more-likely) or wetter episodes in the form of rain or showers (slightly less-likely)
  • Temperatures will vary, with some large day-to-day swings possible, but overall are likely to be near average

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.
