South East England

Cloudy but dry with strong gusty winds.

• Dry overnight with some patchy cloud and clear spells, especially after midnight
• Winds easing
• perhaps allowing a few fog patches to form inland by dawn
• Minimum Temperature 4C

Thursday:

• Dry start with bright spells after any early fog patches clear
• Turning cloudier into the afternoon, perhaps with a little patchy drizzle in places
• Increasingly breezy but mild
• Maximum Temperature 11C

Day 3-5 : Outlook for Friday to Sunday:

• Band of rain moves erratically east on Friday, drier conditions to follow with winds easing
• Mostly dry for Saturday, with strong winds and further rain on Sunday
• Staying mild

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

Hampshire Air Quality (Pollen and UV)

Updated: Wed, 10-Dec 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

Hampshire Visibility

Updated: Wed, 10-Dec at 23:36

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)

Hampshire 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.

Hampshire 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!
