Met Office Forecast

Wales

Rain clearing overnight. Sunshine and showers on Friday.

This Evening and Tonight:

Cloudy this evening with some outbreaks of rain, mainly confined the the east. Becoming mostly dry during the early hours, barring the odd shower in places. Minimum Temperature 10C.

Friday:

A bright start with most places then seeing plenty of sunshine during the day. A few showers are likely, especially further north and east. Maximum Temperature 19C.

Outlook for Saturday to Monday:

A largely dry weekend for many with some good spells of sunshine and becoming warmer. Cloudier on Monday as rain, perhaps heavy in places, increasingly affects the northwest.

Day 6-7 and Week 2:

Through the majority of this period, it will be mostly dry and settled for many areas, especially in the south of the UK. More unsettled conditions with spells of rain and strong winds may affect the north and northwest at times. These unsettled conditions could spread to other parts of the UK later in this period, but widespread unsettled conditions are unlikely. Temperatures are likely to be mostly around normal, although it may become warm for a time in the south and perhaps very warm in the southeast. Towards the end of the period, conditions may start to trend towards more generally settled weather for most areas, but with the possibility of the occasional bout of wetter weather.

Week 3 and 4:

Although confidence remains low throughout this period, the preferred scenario favours a more settled regime. There should be plenty of dry, fine weather around, though there is still the risk of occasional bouts of rain and strong winds. Such spells are mostly likely across the north and west, but they could spread to other areas at times. Temperatures generally around average, with any periods of particularly warm weather most likely being short-lived.

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!
