Wales

Mixture of sunshine and showers. Windy near the coast.

Today:

A cloudy start with a band of light rain and drizzle in the east. Rain soon clears to leave a mixture of sunny spells and scattered showers for most. Windy near the coast. Maximum Temperature 16C.

Tonight:

Rather cloudy this evening with a few showers lingering. Clear spells develop for a time overnight, then further showers during the early hours with strengthening winds. Minimum Temperature 5C.

Monday:

A windy day with sunny intervals and scattered showers. These showers could turn heavy and thundery at times, easing by the evening. Maximum Temperature 15C.

Outlook for Tuesday to Thursday:

Remaining rather windy and unsettled throughout. Some sunshine although showers or longer spells of rain at times too. Nights remaining milder but days returning to average.

Day 6-7 and Week 2:

Cloudy on Thursday starting with outbreaks of rain and showers, especially in the southwest of the UK. Showers are expected to become more widespread during the day, with these heavy and potentially thundery for the south. The breeziest conditions expected in the far northwest. Remaining showery for the rest of the week with the chance of a brief settled spell from the west into Friday. The unsettled theme then continues through the remainder of this period, with longer spells of rain and showers in between, the clearest conditions are most likely in the north. It's likely to be breezy at times; especially around coastal areas, where gales may occur. Temperatures will be near to or slightly below average, though with the formation of overnight frosts becoming unlikely.

Week 3 and 4:

Confidence remains low for this period with weather conditions typical for Spring. A mixture of sunny spells and showers is likely, especially at first, with areas in the south experiencing the most settled and dry conditions through this period. Towards the north and northwest there is an increased chance of unsettled weather as longer spells of rain and strong winds arrive from the Atlantic at times. Temperatures likely to be around average.

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!
