Updated: Fri, 27-Dec at 17:38

North West

Often cloudy with patchy mist, fog and drizzle.

• Remaining cloudy and rather murky overnight with fog and hill fog reforming
• Patchy drizzle remains likely over western hills throughout the night
• Mild for all with light winds
• Minimum Temperature 6C

Saturday:

• A cloudy and murky start, though some brighter spells developing for a while before patchy rain arrives from the north through the afternoon
• Turning drier and cooler later
• Maximum Temperature 9C

Outlook for Sunday to Tuesday:

• Brighter and breezier on Sunday
• Windy with rain later on Monday, then windy with blustery showers or longer spells of rain on New Years Eve but detail remains low confidence

UK Day 6-7 and week 2

• The first of January will see any rain across the UK eventually clearing southeast, followed by cold air as a northerly wind develops
• Showers of rain and sleet will turn increasingly to snow, especially across the north
• This cold, showery northerly may persist for a few days before high pressure builds from the west, bringing a period of more settled weather
• Although it will feel cold at first, temperatures will gradually recover to nearer average for the time of year, perhaps even mild
• Beyond this, a fairly changeable picture is most likely although confidence in details is, as usual at this range, very low
• Wettest and windiest weather in the north and west, whilst the south and east will probably remain more settled overall

UK Week 3 and 4

• A few sleet or snow showers are possible at first, mainly across eastern parts of England and Scotland
• Any showers will ease as high pressure builds across the UK from the west
• This will bring generally settled conditions, and variable cloud amounts could lead to frost and fog developing where skies clear at night, potentially lingering for much of the day in some places
• High pressure may continue to hold on across the south through most of January, but showers are still possible around southern and eastern coasts if the wind is from offshore
• Further north and west it is possible that strong wind, rain and snow may return if unsettled conditions in the Atlantic start to make inroads towards the UK

Cumbria Air Quality (Pollen and UV)

Updated: Fri, 27-Dec at 17:36

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

Cumbria Visibility

Updated: Fri, 27-Dec at 17:36

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)

Cumbria 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.

Cumbria 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!
