Day 6-7 and Week 2:

Through the beginning of the period, it will be mostly dry and settled for many areas, especially in the south of the UK. More unsettled conditions with spells of rain and strong winds are likely to affect the north and northwest at times. There is a chance that these wetter interludes could spread more widely and affect much of the UK. Temperatures are likely to be mostly around normal, although it may become warm for a time in the south and perhaps very warm in the southeast. Towards the end of the period, more settled conditions are likely to develop, across many parts. Spells of wetter and windier weather are possible across northern and western areas at times.

Although confidence remains low throughout this period it is likely that settled conditions will persist across many areas towards the end of July.

Temperatures generally around average, with any periods of particularly warm weather most likely being short-lived and generally across the south.

Met Office : South East England : 2020-07-14T01:03:04

Daylight : Buckinghamshire

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 : Buckinghamshire

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!
