South East England
Largely dry with clear spells overnight. Some coastal showers.
This Evening and Tonight:
It will be largely dry with clear spells this evening and overnight, especially inland. However, there will be further scattered showers feeding into some English Channel coastal counties, these will occasionally be heavy with the risk of hail and thunder. Minimum Temperature 7C.
Windy with sunny spells and scattered blustery showers. These may be heavy at times with the risk of hail and thunder, especially along the south coast. Windy and cold. Maximum Temperature 13C.
Outlook for Thursday to Saturday:
Windy on Thursday with outbreaks of heavy rain, although this should ease Friday. Windier again on Saturday but some brightness before rain is possible later. Milder for all.
Day 6-7 and Week 2:
The first few days of November will likely see unsettled conditions with outbreaks of rain, followed by a more showery regime with strong winds and possibly gales at times. The north of the UK is more likely to see any longer spells of rain and showers which develop, as well as strong winds and possibly gales. By the end of the first week of November, there will be a transition from predominantly low pressure to high pressure, with winds becoming light. Initially in the period, temperatures will likely recover to near-normal. With the transition to high pressure, the UK will see drier and settled weather. Temperatures may start to feel rather cold, with overnight fog and frost becoming more common, particularly in the south.
Week 3 and 4:
Settled weather is likely to continue until the middle of November, with high pressure looking to dominate. This will bring dry and settled conditions, especially for the south of the UK whereas any wet windy weather will be mostly confined to the north. Confidence lowers 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 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 : 2020-10-27T13:34:37
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!
