Met Office Forecast

Wales

Fine today with plenty of sunny spells.

Today:

After a cold and breezy start today, it will be fine with plenty of sunny spells and winds easing throughout the day. Feeling generally cool but pleasant in the sunshine. Maximum Temperature 17C.

Tonight:

Remaining mostly dry tonight with a mixture of clear spells and patchy cloud. Another cold night with a chance of frost Minimum Temperature 1C.

Monday:

Generally cloudy on Monday with outbreaks of light rain throughout the day. However, it will likely be warmer and less windy than the weekend. Maximum Temperature 18C.

Outlook for Tuesday to Thursday:

Mostly dry with sunny spells on Tuesday. Turning increasingly unsettled and windy from Wednesday with rain, sometimes heavy, moving in. Similar on Thursday, with only brief dry interludes.

Day 6-7 and Week 2:

An unsettled period, with plenty of showers and some occasional longer spells of rain across much of the country, the heaviest and most widespread areas likely in the west or northwest, and only limited drier interludes. Often windy, with a risk of gales at times (potentially severe), particularly around coastal regions and within areas of more significant rainfall. With time, northern parts of the UK may tend to become drier and more settled overall, with low pressure systems tending to track further south. Feeling cold, especially so where there is persistent rain and strong winds. Frost is possible at night in any calmer period, becoming increasingly likely for the northern half of the UK later in this period.

Week 3 and 4:

A potential change in the weather is anticipated around the middle of October. Whilst further rain and strong winds are likely at times, spells of fine and dry weather could become more widespread and long-lived. At night, these calmer conditions could allow frost and fog to form more readily. At this time of year, there is potential for fog to linger well into the daytime. Overall, temperatures probably recovering close to the seasonal average for mid-October.

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!

Today

Fine with plenty of sunshine. Winds easing but still feeling chilly over the summits.

Summary Dry through the overnight period with lengthy clear periods allowing it to become cold with a touch of frost in the valleys. Sunday will be another fine day with blue skies and sunshine for most of the national park. Some thin high cloud may arrive during the afternoon, however skies will remain mostly sunny. Winds will be lighter than over the last couple of days and therefore it will feel less chilly, although there will still be a noticeable wind chill on some of the highest ridges and summits. Staying dry and mostly clear well into the evening.
Chance of Cloud free tops 90% to almost certain. A few ribbons of cloud may develop in some valleys just after dawn and the odd patch of fair weather cloud will develop above 950m, but otherwise little if any cloud is expected.
Ground conditions
Visibility Superb visibility with excellent air clarity allowing distant hills and landmarks to be clearly visible.
