Pulborough to Amberley walk

Met Office Forecast

South East England

Mainly fine with some sunny spells.

Today:

It will be a chilly start, with areas of fog clearing by late morning. This will leave a fine day with sunny spells and light winds, although this will allow mist to return late in the day. Maximum Temperature 9C.

Tonight:

Areas of mist and fog will form readily through the evening, with some dense patches developing overnight. More lasting clear spells will also lead to a sharp frost in places. Minimum Temperature -5C.

Tuesday:

Areas of mist and fog are likely to prove slow to clear, perhaps persisting all day in some spots. Otherwise, gradually brightening to a fine day with some sunny spells. Maximum Temperature 9C.

Wednesday to Friday:

Unsettled midweek, with rain moving gradually south. Brighter, breezier and colder conditions will eventually follow, with more settled conditions re-establishing for the remainder of the week, with frosts and fog.

UK: day 6-7 and week 2:

Through Friday and into the weekend it is expected to be dry for many but often rather cloudy, with some light rain at times in the far north. For the rest of the period high pressure is likely to dominate, particularly in the south of the country, resulting in drier and more settled weather with the possibility of overnight frost and fog which may linger through the day. Any unsettled weather is likely to be in the north and northwest with rain at times but otherwise predominately dry. It will also be windy in the north at times. Temperatures are expected to be around or slightly above average, although colder where fog persists by day.

UK: week 3 and 4:

High pressure is expected to remain dominant across the UK. This means that generally settled conditions will prevail with bright or sunny spells for many. There is the ongoing likelihood of overnight frost and fog, which may linger in places. Into February outbreaks of rain and stronger winds are likely at times across the north, whereas settled conditions are likely to persist in the south. Temperatures are expected to be slightly above average, particularly in the north, however some colder interludes remain possible, bringing a risk of occasional snow, this most likely over northern hills.

Met Office : South East England : 2022-01-17T01:06:49

Daylight : West Sussex

Day length is dusk to dawn. Times will vary a little if there is a hill on the horizon.

It should still be light enough to read at dawn and dusk, so there will be enough light for walking even earlier (later).

Moonlight : West Sussex

Notes

• The moon's phase or fracillum (percentage of the moon illuminated) doesn't vary much with location.
• A full moon is not just bigger, its much brighter. A half moon ('50%') give less than 5% of the illumination of a full moon. You can walk with a half 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!
