Met Office Forecast
South East England
Rain will spread eastwards across all parts today. Windy too.
Dry and bright at first. However, cloud and rain, heavy at times, will arrive from the west by mid-morning and quickly spread eastwards during the afternoon. The rain will be accompanied by strengthening southwesterly winds. Becoming drier later. Turning milder. Maximum Temperature 15C.
Cloudy and largely dry at first, with perhaps a few clear spells developing. However, cloud and some rain will move southeastwards during the early hours. A windy but milder night. Minimum Temperature 12C.
Rather cloudy with further outbreaks of rain during Friday, although there will be some drier and occasional brighter interludes. Windy at first, easing later. Very mild for time of year. Maximum Temperature 17C.
Outlook for Saturday to Monday:
Unsettled, with successive spells of wet and windy weather sweeping eastwards, especially this weekend, with risk of gales. Some drier interludes in between. Further rain likely on Monday. Mild throughout.
Day 6-7 and Week 2:
Conditions are expected to remain unsettled into the beginning of November, with outbreaks of rain at first, followed by a more showery regime. Strong winds are also likely to continue for the first few days of November, with gales possible at times. However, it will likely feel milder, particularly in the south. A change to more settled conditions is then expected midway through this period with any showers or longer spells of rain most likely affecting northern areas. Elsewhere, the south of the UK has an increased likelihood of seeing the best of this dry and settled weather. Winds possibly becoming light across the south with the strongest winds confined to the north. These more settled conditions bring an increased risk of colder weather with overnight frost and morning fog.
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 : 2020-10-29T02:02:02
Daylight : Surrey
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 : Surrey
- 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!
