Weather data by Met Office
Regional weather (Met Office)
Sunset: 15:59. Dusk: 16:39. Dark: 17:23. Moon not visible
Updated: Mon, 30-Dec at 23:38
East England
Staying mild and rather cloudy overnight. Turning breezy Tuesday.
- Some clearer spells possible at first, but cloud likely thickening again during the evening and overnight
- The breeze also tending to strengthen toward daybreak
- Remaining rather mild
- Minimum Temperature 6C
Tuesday:
- Cloudy and rather windy conditions, perhaps with a few brighter breaks at times
- However, outbreaks of rain will extend erratically south and east through the evening
- Still mild
- Maximum Temperature 11C
Outlook for Wednesday to Friday:
- Wednesday, windy with some heavy rain later, perhaps turning wintry as it clears overnight
- Much colder Thursday and Friday with strong winds and isolated wintry showers gradually easing
UK Day 6-7 and week 2
- A cold start to this period, with overnight frost and a mix of snow, sleet and rain showers in the north
- Milder air may make inroads from the south during the first weekend, bringing snow, rain and perhaps strong winds, but the northern extent of this is unclear and it may be that most or all of the UK remains in the colder air
- The second week of January then looks rather varied, with high pressure, cold air and wintry showers more likely across the north, spells of rain and strong winds more likely in the south and an uncertain balance between these two regimes
- Overall, temperatures are more likely to be below normal than above, but day to day variation is likely
UK Week 3 and 4
- Slowly-evolving weather patterns look most likely mid-month, although the flavour of the weather depends on the balance of high and low pressure - initially it may well be a continuation of similar conditions to the week before
- As we go through the month, it is possible that spells of strong wind, rain and snow may return more widely as unsettled conditions in the Atlantic start to have more influence over the UK
- There are no strong signals for any significant cold snap, but day to day variation of temperatures is likely and there will probably be some cold interludes between milder spells

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!
