Wales

Chilly with scattered showers mixed with a few sunny spells.

  • Early evening showers soon fade away, leaving a dry and settled evening
  • Turning cloudier overnight with showers arriving from the north, turning wintry over the hills
  • Feeling chilly with clear skies allowing frost and patchy ice to form in places
  • Minimum Temperature -2C

Friday:

  • A chilly start with a continuation of sunny spells and scattered showers, these heavy and wintry at times before easing through the evening
  • Winds remaining light
  • Maximum Temperature 8C

Outlook for Saturday to Monday:

  • Drier and more settled over the weekend, with some sunny spells
  • Still rather chilly with overnight frosts, but feeling pleasant in afternoon sunshine
  • Cloudier with a few showers on Monday

UK Day 6-7 and week 2

  • High pressure is expected to be centred to the east of the UK for much of next week
  • Initially there should be a good deal of dry weather with sunny spells by day, but still the potential for some chilly nights at first
  • Daytime temperatures will probably start around average, but gradually increase day by day
  • As we move towards the weekend and into the following week, we are likely to see a gradual transition to less settled conditions
  • So rain or showers are expected at times, mostly focussed across the south and west at first, then more widely later
  • With winds predominantly coming from the south or southwest it will also become much milder, possibly warm in places

UK Week 3 and 4

  • Confidence is low, but changeable weather patterns are most likely at the end of March
  • This means periods of unsettled, wet and windy weather interspersed with some drier and brighter spells
  • Into early April, there may be a transition to more frequent drier and more settled spells
  • Temperatures will probably be above average overall

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.
