Met Office Forecast

Wales

Frequently sunny, before turning cold and wet midweek.

Today:

A cloudy start in places with fog patches, mostly confined to the east of the country, lingering in the morning. Otherwise a fine and dry day with plenty of sun. Remaining mild, particularly under any sunshine. Maximum Temperature 11C.

Tonight:

Fog reforms into the night, at first in the east but gradually moving westwards. Some coastal areas stay clear however, and here frost is likely to form. Chilly. Minimum Temperature 0C.

Tuesday:

A fine day with plenty of sunshine for most, but a cloudy day with lingering fog for some eastern areas. Mild in the sunshine but feeling colder under any cloud. Maximum Temperature 11C.

Outlook for Wednesday to Friday:

Becoming cold and cloudy, with showers in the south Wednesday. Then turning drier Thursday, though still with some patchy light rain. Cloud cover then become patchy, giving sunny spells Friday.

Day 6-7 and Week 2:

Confidence is high for this period as local high pressure is expected to give a mostly settled outlook. With the high most likely centred over Scotland, this will bring a cold northerly air flow and a possibility of light sleet and snow flurries for a time into northern and eastern coasts. Otherwise most areas will stay fine and dry with plenty of sunny spells. Any spells of rain and stronger winds are most likely to occur in the north and west where front incursions are most likely, or into the south around the base of the high. Where skies clear overnight, frost and fog patches may become prevalent. Temperatures are likely to start off colder than normal, due to the northerly air flow, before slowly returning to around average.

Week 3 and 4:

By the middle of March we see a trend towards more unsettled conditions with spells of rain and showers but with some drier interludes. Rain perhaps becoming more confined to the north and west at times with the south and east seeing some more prolonged settled periods. Temperatures are most likely to remain around or a little above average and whilst there are no signals for prolonged cold, some brief colder intervals continue to remain possible.

Day length is dusk to dawn. Times will vary a little if there is a hill on the horizon.

It should still be light enough to read at dawn and dusk, so there will be enough light for walking even earlier (later).

Notes

  • The moon's phase or fracillum (percentage of the moon illuminated) doesn't vary much with location.
  • A full moon is not just bigger, its much brighter. A half moon ('50%') give less than 5% of the illumination of a full moon. You can walk with a half 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!
