Today
Tue, 17-Jun

A cloudier day compared to Monday with some brisk winds and rain and drizzle.

Occasional sunny spells especially in the southeast during the morning but increasingly cloudy with drizzle in the northwest.

Occasional strong winds at higher elevations though generally easing through the day.

Medium risk Poor Visibility Strong Sunlight
Medium risk Poor Visibility Strong Sunlight
Chance of Cloud free tops 30% in the northwest, but 70% in the morning in southeastern parts.
Ground conditions Please see - https://yrwyddfa.live/
Visibility Patchy low cloud mainly on higher summits initially (above around 600m), but lowering, especially in the northwest with time to around 300-500m. There is a chance for lower bases on windward western slopes during the afternoon and evening. The greatest chance for any further cloud breaks and higher cloud bases will be in southeastern areas. Visibility generally moderate to good, but occasionally poor in rain and drizzle and very poor in cloud covering the hills.
Confidence High confidence for mostly fine and warmer conditions developing this week. Moderate confidence for cloud and rain detail on Tuesday.
View Wind gusts affecting most summits and some ridges may reach around 35-40mph at first, with sudden strong gusts on lee slopes. Note the deterioration in navigation conditions later in the day. Moderate UV levels are possible before it clouds over, so sun protection should be considered.

Visibility in km. Above 50km is 'good'. Humidity and air pollution make it worse. Theoretical maximum is 300km/200 miles in clean dry polar air.

On the South Downs, at ~ 170m/500ft, the horizon is is ~ 45km/30 miles away. On a mountain at 1,000m/3,000ft, it is ~ 160km/100 miles away. Formula: horizon in km = √ (13 x altitude in m)

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!
