South West England

Mostly dry, with variable amounts of cloud.

• Clear this evening, then some cloud developing overnight
• Turning breezy again around coasts and hills
• Feeling fresh by Thursday morning, perhaps with isolated patches of mist and fog in sheltered spots
• Minimum Temperature 7C

Thursday:

• A chillier start than recent days
• Dry for much of the day, though cloud gradually thickening which may bring some rain later
• Often breezy, with similar temperatures to Wednesday
• Maximum Temperature 12C

Day 3-5 : Outlook for Friday to Sunday:

• Early rain clearing, then fine on Friday
• Lighter winds
• Turning windy again over the weekend
• Sunshine on Saturday, then cloudier on Sunday with some rain
• Temperatures average or just above

UK Day 6-7 and week 2

• The current unsettled spell of weather is likely to continue through much of next week
• Further spells of rain are expected, likely to be heavy and prolonged at times, particularly in the west and northwest
• Some drier spells of weather are also likely, these most reliably across southeastern parts of the UK
• Often windy, especially in the north and west where there is potential for a spell of very strong winds to develop for a time early next week
• Generally mild with any overnight frost patchy and mainly in the north
• There are signs that conditions may become less disturbed heading towards the Christmas period, with the potential for high pressure to build bringing drier conditions, with the risk of overnight frost and fog patches increasing

UK Week 3 and 4

• Moving into late-December and early January, there are signs that the persistent pattern of mild and wet weather, which has characterised the month so far, may ease somewhat, with a chance of high pressure becoming more influential
• Compared to recently, the chance of dry, settled patterns of weather is higher with frost and fog more prevalent
• Spells of rain and strong winds remain possible, but these are more likely to less frequent compared to the month so far
• The chance of snowfall is likely to be higher than earlier in the month, particularly high ground in the north
• Whilst the chance of impacts from cold weather is higher compared to earlier in the month, the likelihood of more widespread snow and ice remains very low

Exmoor Air Quality (Pollen and UV)

Updated: Wed, 10-Dec at 20:37

Key : Low Medium High Very High

Pollens

These pollens are shown (in season):

• Grass
• Alder and birch (trees)
• 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

Exmoor Visibility

Updated: Wed, 10-Dec at 20:36

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)

Exmoor 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.

Exmoor 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!
