Met Office Forecast
South East England
Rather cloudy, breezy and milder today.
A rather cloudy day, with outbreaks of patchy light rain and drizzle at times. Perhaps drier and brighter in the far southeast around Kent during the afternoon. It will stay on the windy side, especially along the coasts. Feeling milder. Maximum Temperature 16C.
Cloud and outbreaks of rain will clear northwards during the evening to leave a largely dry, but rather cloudy night for most. Perhaps occasional clear spells developing. Breezy and mild. Minimum Temperature 12C.
A largely dry and bright start to Saturday. However, a band of rain, heavy at times, will move eastwards across all parts during the afternoon. Windy, with coastal gales possible. Maximum Temperature 16C.
Outlook for Sunday to Tuesday:
Early rain and strong winds quickly clearing east on Sunday, with drier and brighter conditions following. Staying unsettled, with a mixture of sunshine and showers Monday and Tuesday. Feeling cool.
Day 6-7 and Week 2:
Following the very unsettled period we are now in, conditions across the UK are expected to become less unsettled early next week. By next Tuesday, most places will have a mixture of sunny spells and showers, the heaviest and most frequent of these showers likely in the west. By the middle of next week, generally much drier, brighter more settled conditions are likely to be established across much of the UK. As winds fall light for many, overnight frost and morning fog will become more prevalent and it will be colder generally. More changeable windier conditions may persist in the far north. Generally quiet conditions will probably persist through the following weekend although it may start to become somewhat more changeable again as we go into mid November.
Week 3 and 4:
Settled weather is likely to continue until the middle of November, with high pressure looking to dominate. This will bring generally dry conditions, especially for the south with any wet and windy weather being mostly confined to the north. Confidence is currently low for the second half of November but current signals suggest an autumnal setup with colder conditions developing and more frequent showers, with the heaviest of these showers affecting the east and northeast of the UK. Another spell of drier, more settled conditions is possible towards the end of November, but confidence remains low for this. Despite the settled conditions in the south temperatures are expected to be lower than average for the time of year, whereas they will be closer to normal in the north.
Met Office : South East England : 2020-10-30T01:03:46
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
- 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!
