Met Office Forecast

South East England

Extensive low cloud and fog away from the south coast.

Today:

A dull start to the week away from the south coast with widespread fog. Fog will likely lift to low cloud and clear for most, bringing bright spells later. Bright and sunny all day along the south coast. Maximum Temperature 12C.

Tonight:

Fog and low cloud soon reforming this evening, becoming extensive and widespread overnight, with a risk of grass frost in rural locations. Rather cold, especially in the west. Minimum Temperature 0C.

Tuesday:

Mostly cloudy on Tuesday with early widespread fog lifting into low cloud then clearing as it burns back to coasts. Some sunny spells developing, but fog reforming once again overnight. Maximum Temperature 12C.

Outlook for Wednesday to Friday:

Mostly cloudy and foggy Wednesday, with brief brighter spells. Rather cloudy initially on Thursday, perhaps with a spell of rain followed by clear, dry and cold conditions into Friday.

Day 6-7 and Week 2:

Confidence is high for this period as local high pressure is expected to give a mostly settled outlook. With the high most likely centred over Scotland, this will bring a cold northerly air flow and a possibility of light sleet and snow flurries for a time into northern and eastern coasts. Otherwise most areas will stay fine and dry with plenty of sunny spells. Any spells of rain and stronger winds are most likely to occur in the north and west where front incursions are most likely, or into the south around the base of the high. Where skies clear overnight, frost and fog patches may become prevalent. Temperatures are likely to start off colder than normal, due to the northerly air flow, before slowly returning to around average.

Week 3 and 4:

By the middle of March we see a trend towards more unsettled conditions with spells of rain and showers but with some drier interludes. Rain perhaps becoming more confined to the north and west at times with the south and east seeing some more prolonged settled periods. Temperatures are most likely to remain around or a little above average and whilst there are no signals for prolonged cold, some brief colder intervals continue to remain possible.

Met Office : South East England : 2021-03-01T02:14:57

Daylight : London

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 : London

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!
