Wales
Mainly cloudy with spells of rain across the mountains.
- Cloud steadily thickens from the west through this evening, bringing widespread hill cloud and spells of light rain and drizzle across the higher ground
- Some further spells of rain possible around the coasts overnight
- Mild with winds gradually easing
- Minimum Temperature 11C
Wednesday:
- Cloudy at first but becoming brighter through the day with even a few breaks to sunshine
- Feeling warm and humid, with scattered showers spreading from the south by the evening
- Maximum Temperature 24C
Outlook for Thursday to Saturday:
- A mainly cloudy period with spells of rain at times, but some drier interludes as well
- Breezy at times, but winds easing by Saturday
- Increasingly warm and feeling rather humid
UK Day 6-7 and week 2
- A low pressure system passes to the northwest of the UK early in the period bringing wetter windier conditions to the northwest
- Drier in the southeast at first before the wetter conditions move through the early part of the week
- From there further low pressure systems are likely to the northwest of the UK at times, bringing wet and windy conditions to the northwest
- Whilst some rain or showers are possible across the south and east, longer drier spells are more likely, under the influence of higher pressure
- There is also the chance of some occasional very warm, perhaps locally hot weather, as brief bursts of hotter air encroach from the continent, but probably fairly short-lived and perhaps also accompanied by a few thunderstorms at times
UK Week 3 and 4
- Conditions will likely continue to be changeable through much of July
- The wettest and windiest conditions most likely towards the northwest with a risk of some heavy rain at times, especially over hills
- Southern and eastern areas are most favoured for longer drier and more settled spells, although even here some occasional rain or showers will be possible, perhaps thundery
- There are signs of more widely settled weather during the second half of July, however this signal is very tentative
- Temperatures are expected to be above average for most areas, especially towards the southeast where there will be an ongoing chance of some very warm or hot conditions at times

Visibility in km. Above 50km is 'good'. Humidity and air pollution make it worse. Theoretical maximum is 300km/200 miles in clean dry polar air.
On the South Downs, at ~ 170m/500ft, the horizon is is ~ 45km/30 miles away. On a mountain at 1,000m/3,000ft, it is ~ 160km/100 miles away. Formula: horizon in km = √ (13 x altitude in m)

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!
