East England

Dry with clear skies overnight. A widespread frost.

• Skies becoming increasingly clear from the east this evening as cloud continues to recede to the north and west
• It will be a chilly night under clear skies, with a widespread frost
• Winds falling light
• Minimum Temperature -3C

Sunday:

• A clear, cold and frosty start on Sunday
• Staying dry, with lengthy spells of sunshine and light winds throughout the day
• Temperatures recovering in the sunshine
• Maximum Temperature 7C

Outlook for Monday to Wednesday:

• Dry and bright on Monday
• Largely dry Tuesday, ahead of a weakening rain band arriving late in the day
• Dry and sunny Wednesday
• Frosty nights but temperatures recovering by day

UK Day 6-7 and week 2

• It is likely to be rather more settled across the UK in this period, especially at first
• High pressure will sit close to, or over the UK, and will most likely drift away slowly eastwards with time
• Consequently, southern and eastern areas are likely to see the driest conditions, with lightest winds, which could lead to overnight frost and fog with temperatures a little below normal
• Further north and west, there is a risk of incursions of Atlantic air and fontal systems at times, which would bring some rain here, but with milder temperatures
• There is a very low chance that if the high orientates in such a way that a more easterly (rather than southerly/southeasterly) flow develops, a spell of much colder conditions could develop across the UK

UK Week 3 and 4

• It is most likely that high pressure will dominate at first in some form or another, but there is a weak signal for a more unsettled spell in the second half of the month, before signals become indistinguishable from climatology by the start of March
• Temperatures may be below average at first, with overnight frosts, but could return to near average or even rise a little above average later
• Rainfall amounts, especially in the south and east are likely to be below average at first, but may return to near-normal values later in the month

Essex Air Quality (Pollen and UV)

Updated: Sat, 01-Feb at 23:36

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

Essex 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)

Essex 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.

Essex 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!
