East England
Turning settled this week, mild but mostly cloudy.
- Becoming generally cloudy as a little light rain and drizzle spread eastwards during the evening
- Parts of the east staying dry and all parts should be dry by dawn
- Gradually becoming milder, with frost not expected
- Minimum Temperature 4C
Tuesday:
- Mild but on the cloudy side, with many areas staying dry, although the odd spot of rain remains possible
- Some limited brighter spells more likely in the afternoon
- Maximum Temperature 13C
Outlook for Wednesday to Friday:
- Predominantly settled, mild and cloudy conditions are expected for the Christmas period, with winds gradually easing
- Limited overnight frosts
UK Day 6-7 and week 2
- The start of this period will be characterised by mild, cloudy conditions for most, with some drizzle in places, and more persistent rain across northwest Scotland, which will probably start to spread southeast
- Many other areas will be predominantly dry but rather cloudy, with the best cloud breaks likely to be found across parts of eastern Scotland and Northeastern England
- By the turn of the year, it looks more probable that colder, more unsettled conditions will likely make at least some ingress into northern and central areas, bringing a risk of some impacts from rain, wind, and maybe even ice, sleet and snow
- Widely mild at first, but temperatures probably return to nearer normal by early January
- Throughout, any clearer spells overnight may lead to localised frost and fog
UK Week 3 and 4
- Confidence in this period is fairly low, but overall, slowly-evolving weather patterns are more favoured
- Continuing from the previous period, there remains a slightly reduced chance compared with normal of wet and windy spells, with a slightly greater potential for colder episodes during the first half of January
- While drier than average conditions are likely for many areas, some precipitation is still expected, which could lead to wintry hazards at times
- Temperatures are likely to be close to or a little above normal overall, but this could be made up of a mix of milder and colder interludes

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!
