Met Office Forecast

South East England

Fine with sunny spells for most. Risk of heavy showers.

Today:

A fine start for most, with early cloud breaking to give some warm sunny spells. Whilst most places will stay dry, cloud will build through the day, bringing a risk of showers. These potentially heavy across eastern parts. Light winds. Maximum Temperature 24C.

Tonight:

Daytime showers soon fading, to leave a dry night with clear spells. The odd patch of mist or fog is possible beneath any clearer skies, but soon lifting after dawn. Minimum Temperature 11C.

Tuesday:

A fine, dry but rather cloudy morning. Cloud breaking through the day, with some warm sunny spells developing. although feeling fresher in the southwesterly breeze. Maximum Temperature 23C.

Outlook for Wednesday to Friday:

Breezy, with rain possible for a time Wednesday, easing away east later in the day. Fine, increasingly sunny and tuning very warm Thursday. Sunny and potentially very hot Friday.

Day 6-7 and Week 2:

There are increasing signs that many parts will become drier, brighter and very warm to start the period with the warmest and driest weather focused across the southeast of the UK. However, northwestern parts will probably stay more unsettled with further rain at times. Somewhat cooler conditions may follow from the west over the weekend, perhaps preceded by showers or thunderstorms. For the following week, a fair amount of dry, bright warm weather looks likely for much of the UK with the possibility of some further very warm weather, especially in the southeast. There may well be more changeable, breezy interludes with some rain or showers, more especially for northwestern areas where temperatures will be generally nearer normal.

Week 3 and 4:

This period is likely to see a mixture of dry and settled conditions, interspersed with occasional bouts of wetter and windier weather. The majority of the unsettled weather seems more likely to be in the northwest, with the south and southeast seeing the driest conditions. Temperatures will probably be around or slightly above the average for this time of year. There may be further short lived very warm spells, these more likely across the south or southeast. There are some tentative signs that conditions could become more widely dry and settled across the UK towards the end of the month.

Met Office : South East England : 2020-08-03T01:34:05

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!
