South East England

Remaining mild through to the weekend.

  • A continuation of the recent cloudy and mild weather is forecast for Boxing Day
  • Although perhaps a greater chance of early morning fog patches which will be slow to clear, and for more persistent overcast skies later
  • Maximum Temperature 10C

Tonight:

  • Cloud tending to thicken across the region with further patchy light rain or drizzle
  • Quite misty generally perhaps with fog forming later in the night further east
  • Minimum Temperature 4C

Friday:

  • Another cloudy mild day with light winds and patchy fog which may be slow to clear
  • Some rain or drizzle, especially further west
  • Maximum Temperature 8C

Outlook for Saturday to Monday:

  • Cloudy on Saturday though most parts staying dry
  • Sunday and Monday should be a brighter days, breezy, perhaps with the odd shower and temperatures nearer average for late December

UK Day 6-7 and week 2

  • An erratic change from the mild and largely settled conditions of the past few days is expected
  • Rain, stronger winds and some snow already across Scotland may on Tuesday become more severe and start to push southwards through the middle part of next week, bringing a chance of snow to other parts of the UK, along with colder conditions more widely
  • A period of more settled weather then seems probable later next week, with a gradual recovery in temperatures to nearer average for the time of year, perhaps even mild
  • Beyond this, a fairly changeable picture is most likely although confidence in details is, as usual at this range, very low
  • Wettest/windiest weather in the north and west, whilst the south and east will probably remain more settled overall

UK Week 3 and 4

  • Confidence in this period is fairly low, but continuing from the previous period, there remains a chance of rather unsettled and cool conditions continuing at first, with the wettest conditions perhaps focussed more over the south (still with a risk of snow on the northern edge), with sleet and snow showers further north
  • Then, through the rest of January, something more climatological could return with the wettest and coolest conditions further north, and with higher pressure further south, it is more likely to be drier, and at times milder here than elsewhere

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!

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