South East England

Cloud clearing, becoming dry and clear overnight. Sunny spells Friday.

• Clear and dry this evening with cloud gradually clearing Kent coasts
• Overnight, lengthy clear spells developing with frost likely and perhaps the odd fog patch
• Winds remaining light, feeling chilly
• Minimum Temperature 2C

• A chilly start but staying dry, with any fog patches soon clearing

• A largely dry and settled period, with some sunny spells by day
• Overnight frost and fog likely

• Temperatures around average

UK Day 6-7 and week 2

• A split in weather conditions is likely across the UK during early March
• Northwestern areas will see some rain and stronger winds at times, as Atlantic weather systems arrive from the west
• These spells of wet and windy weather will drift southeast to some degree, but will weaken
• High pressure is likely to have more influence across the south of the UK, at least at first
• Here, there should be a good deal of fine/dry weather at first with a chance of night frosts and morning fog patches, but some pleasantly mild afternoons, and feeling warm in the sunshine
• However, towards mid-March, there is an increasing chance of unsettled conditions becoming more widely dominant across the UK with more in the way of rain at times, even in the south

UK Week 3 and 4

• The middle of March is most-likely going to be quite changeable and unsettled with spells of rain and strong winds in most areas, especially the north and west, with rainfall amounts probably above average
• Some drier interludes are also likely between time though, especially in the south and east, and temperatures on the whole will be a little above average
• Later in the month, there are signs that high pressure to the south could start to dominate once again, with extended dry and bright conditions perhaps developing more widely

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!
