Amberley to Pulborough walk

Met Office Forecast

South East England

Chilly for some overnight. Rain spreading east on Monday.

This Evening and Tonight:

Fine with clear spells into the evening, allowing temperatures to drop. This bringing a risk of fog patches and low cloud once again, especially in the east. Thicker cloud into far western areas by dawn. Locally chilly in eastern areas. Minimum Temperature 5C.

Monday:

Chilly start in east with local fog patches clearing, but also some sunny spells. Thickening cloud and outbreaks of rain spreading eastwards. Breezy on coasts. Very mild. Maximum Temperature 18C.

Outlook for Tuesday to Thursday:

Unsettled and rather windy through this period, perhaps especially Wednesday and early Thursday, with spells of rain and heavy showers. Temperatures starting well above average, but trending downwards after midweek.

Day 6-7 and Week 2:

Sunny spells and showers for most areas at the start of this period with some places remaining dry. Feeling breezy at times especially along northern, eastern and southern coasts. Temperatures falling to below average for most across the UK, increasing the likelihood of snow and wintery conditions over higher ground restricted to northern areas. It will likely turn unsettled again over the weekend as cloud, rain and stronger winds arrive from the west. Unsettled conditions then likely to persist towards the end of October across the UK. Temperatures most likely trending up after a colder start to this period. Any further spells of colder weather likely short lived and restricted to the north of the UK.

Week 3 and 4:

Through the end of October and early November the weather is likely to be dominated by systems arriving from the Atlantic. Remaining unsettled and windy with the wettest and windiest conditions in the north and west. Driest conditions across the south especially the southeast with lighter winds but the risk of overnight fog at times. From early to mid-November increasing chance of settled weather but confidence of this is very low. Temperatures are likely to be warmer than average for most. Perhaps some colder spells and an increasing chance of frost and fog towards the end of this period but confidence of this is very low.

Met Office : South East England : 2021-10-17T14:24:33

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!
