Wales

Further warm sunshine after early morning fog clears.

  • Remaining fine and dry this evening and overnight with lengthy clear spells
  • Some mist, fog and low cloud developing and turning chilly with a touch of rural frost in places
  • Minimum Temperature 0C

Wednesday:

  • Any low cloud and fog soon clearing to leave a pleasant day with lengthy spring sunshine
  • A slight breeze but feeling pleasant when sheltered in the sunshine
  • Maximum Temperature 17C

Outlook for Thursday to Saturday:

  • Plenty of warm sunshine on Thursday and Friday after any fog clears readily through the mornings
  • Cloud building on Saturday with increasing chance of showery rain during the weekend

UK Day 6-7 and week 2

  • A transition from the fine and settled conditions most will have seen is expected through this period
  • This will most likely come in the form of a cold front progressing southeast bringing some rain and showers and fresher conditions
  • There is a low risk of heavier, possibly thundery showers coming into the country from the south for a time early in the period, but confidence in this aspect of the forecast is low and these may well pass to the east
  • This heralds a wetter period through the middle of April with showers or longer spells of rain at times, which could be heavy and thundery in places
  • Strong winds could develop in some areas, particularly the south and west
  • Temperatures are likely to return closer to normal

UK Week 3 and 4

  • Some unsettled weather is possible at this start of this period with showers or longer spells of rain in places
  • However, a change to more settled conditions is most likely through this period as high pressure becomes more influential
  • This settled theme continues into early May, although some spells of wetter, unsettled weather remain possible, especially in the south
  • Temperatures are expected to 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!
