Met Office Forecast

South East England

Occasional heavy showers this evening.

This Evening and Tonight:

Heavy, perhaps thundery showers moving east during the evening, clearing just after midnight to leave dry conditions and partly cloudy skies. Light winds with the odd patch of mist by dawn. Minimum Temperature 9C.

Wednesday:

Dry, warm and sunny for much of the day with light winds. Increasing cloud by dusk with rain through the first half of the night, heavy and thundery in places. Maximum Temperature 25C.

Thursday to Saturday:

Dry and mostly sunny on Thursday. A bright start Friday, showers or more persistent, heavier rain later. Bright and breezy Saturday, with isolated showers. Fairly warm, though turning somewhat cooler.

UK: day 6-7 and week 2:

On Sunday and into the start of next week, southern parts of the UK likely staying mostly fine and dry with light winds. Still a chance of showers, and a low risk that some of these will be heavy at times. Further north it is likely to be cloudier and breezier, particularly around coasts, with showers that could merge into some longer spells of rain. Temperatures close to average, but perhaps below average in the northwest, though it will still feel warm in the sunshine. Towards the end of next week, rain or showers are possible, most likely in the northeast by this stage, where it will be breezy. Drier further southwest with lighter winds. Most areas becoming mainly dry through the end of May.

UK: week 3 and 4:

Into June, temperatures are likely to be above average across the south but closer to average further north. Toward mid-June it may turn less settled across the north of the UK, bringing rain or showers, while the south may remain largely fine.

Met Office : South East England : 2022-05-17T13:32:48

Daylight : East 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 : East Sussex

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!
