UK Day 6-7 and week 2

  • The period is expected to begin on an unsettled note, with a spell of cloud, wind and rain sweeping across much of the UK
  • Rain is likely to be heavy in places, and there is a small chance that the winds could end up strong enough to cause some disruption
  • An exception to this may well be the far north of the UK, which could remain in a colder, more showery regime from earlier in the week
  • Winds are expected to turn towards the north following this, with the colder, showery type spreading countrywide, before easing through the weekend as a more settled spell develops
  • The following week is likely to stay fairly unsettled or at least changeable for all, with temperatures rising back to near average

UK Week 3 and 4

  • Typical autumn weather will probably affect the UK with a mix of weather types through the first half of October
  • Periods of unsettled conditions, with wind and rain at times, will likely be interspersed with shorter spells of calmer and drier weather

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
  • Of course, you need a cloudless night as well!

Surrey weather (Accuweather)

Now would be a good time for a cup of tea.
