South East England

Cold and clear, then cloudy with rain overnight.

• Clear spells at first, and temperatures quickly falling with a slight frost developing for many places
• Then becoming cloudy, followed by outbreaks of rain arriving from the northwest later tonight
• Minimum Temperature -2C

Friday:

• Outbreaks of rain through the morning, with perhaps some heavier bursts, will gradually ease to patchy light rain and drizzle
• Perhaps becoming dry and brighter in the far west
• Maximum Temperature 9C

Outlook for Saturday to Monday:

• Dry with often large amounts of cloud, but also some bright or sunny spells, except later Sunday patchy light rain may reach western areas
• Temperatures near or slightly below average

UK Day 6-7 and week 2

• Periods of wet weather are likely to affect northwestern parts of the UK at times, particularly early in this period
• Some heavy rain is possible and this is likely to be accompanied by spells of strong winds
• South of this, across the rest of the UK, it is likely to be more settled and whilst some rain can't be ruled out at times, there is likely to be plenty of dry weather through this period
• Winds will be lighter and this will bring the risk of overnight frost and fog
• Overall, temperatures will be close to normal for most, but it is likely to be mild at times in the northwest
• Brief colder spells are likely here in between weather systems though

UK Week 3 and 4

• There are signs that there may be somewhat of a northwest-southeast split to the UK's weather through this period
• The north or northwest is likely to bear the brunt of wet and windy spells, whilst towards the south or southeast, it may be drier and more settled
• Some rain is still likely at times here though, as are brief drier spells further north
• Temperatures will probably be close to average overall, but some milder spells are likely, especially in the north
• Brief colder spells are likely in between weather systems though, and the south is likely to be at greatest risk of seeing some overnight frost and fog

Key : Low Medium High Very High

Pollens

These pollens are shown (in season):

• Mugwort and Ragweed (weeds)

When out walking, wraparound glasses, a disposable or washable facemask, and being at the front of the group, all help.

Other forecasts: Met Office, University of Worcester

UV and Air Quality

The UV forecast takes account of cloud cover.

"Air Q", the European Air Quality index, is a mix of dust/particulates, ozone, sulphur and nitrous oxides

Buckinghamshire Visibility

Updated: Mon, 20-Jan at 08:36

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)

Buckinghamshire daylight

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.

Buckinghamshire moonlight

Moonlight chart for walking at night.

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!
