Updated: Wed, 16-Jul at 17:38
South East England
Warming steadily. Some heavy showers likely by the weekend.
- Some evening sunshine followed by a dry and mostly clear night with light winds, allowing some mist and low cloud patches to form around dawn
- Minimum Temperature 12C
Thursday:
- Largely cloudy to start, becoming brighter into the afternoon with the odd light shower possible in the west
- Very warm and humid, but cooler near coasts
- Maximum Temperature 28C
Outlook for Friday to Sunday:
- Dry and bright on Friday but very warm and humid with showers or heavy rain developing overnight into Saturday
- Cooler by Sunday, but remaining unsettled with further showers
UK Day 6-7 and week 2
- Overall a rather more changeable pattern of weather through this period, compared to much of the summer thus far
- The first couple of days will likely be dominated by low pressure leading to particularly unsettled weather, with heavy rain and/or thunderstorms in some areas
- Thereafter, a general westerly regime looks to become established, with occasional weather systems moving in from the Atlantic
- This means further rain or showers and breezy conditions at times, especially in the northwest
- This will be interspersed with some drier, sunnier periods
- Temperatures are expected to average out above normal and whilst brief hotter and humid days are possible
- This broad pattern is likely to continue through to the end of July
UK Week 3 and 4
- The rather changeable pattern will likely continue through early August with spells of rain or showers mixed in with some drier, brighter days
- Towards mid-August, there are tentative signs that high pressure may become rather more dominant, which could bring more in the way dry, settled weather more widely
- Temperatures will likely continue to be above average overall, with the possibility of very warm or hot spells developing later in the period, especially further south and east

Notes
- Max Height (solar noon) is when the sun is highest in the sky.
- Day length is dawn to dusk as there is enough light for walking for at least 30 minutes before sunrise and after sunset, even on an overcast day.
- At 'Light' (nautical dawn) the horizon becomes visible. At 'Dawn' (civil dawn) there is enough light to read, and drivers can switch their lights off. Finally the sun rises.
- After sunset, there is still enough light to read until 'Dusk' (civil dusk) or lighting up time for drivers. The horizon is still visible until 'Dark' (nautical dusk).
- Times will vary if there is a hill on the horizon.

Notes
- The percentage of the moon which is illuminated doesn't vary much with location.
- A full moon is not just bigger, it is much brighter. A quarter moon (1/2 disk visible) give less than 5% of the illumination of a full moon. You can walk with a quarter 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
- Sunlight is ~ 1,000,000 times brighter than moonlight.
- Of course, you need a cloudless night as well!
