Met Office Forecast

South West England

Dry and bright days with overnight frosts and fog.

Today:

Any early fog patches will soon clear, leaving another dry and sunny day with light winds. Feeling mild by day, with frost and fog patches developing overnight. Maximum Temperature 12C.

Tonight:

Remaining dry this evening with clear skies overnight. Feeling chilly with light winds allowing for frost in prone spots and localised fog patches to form. Minimum Temperature 1C.

Sunday:

Any morning fog patches will quickly clear to leave a fine and bright day with plenty of sunshine. Staying mild, with frost and fog patches overnight. Maximum Temperature 12C.

Outlook for Monday to Wednesday:

Cloudy at times on Monday and Tuesday with sunny intervals. The odd shower possible in the far west on Tuesday. Outbreaks of rain on Wednesday. Mild throughout with overnight frosts.

Day 6-7 and Week 2:

High confidence for this period as local high pressure is likely to give a mostly settled outlook, with any uncertainty existing with respect to the orientation of this high. Currently the signal suggest a placement over the south of the UK before transferring to the north later next week. This means most areas will stay fine and dry with plenty of sunny spells, and that any spells of rain and stronger winds are most likely to the far north and west of the UK where front incursions are most likely. Temperatures are likely to remain around average for this time of year, however a short cold spell may occur near the end of this period. Where skies clear overnight frost and fog patches may become prevalent.

Week 3 and 4:

Settled conditions are likely at the start of the period, though Atlantic frontal systems may make more progress across the country at times, introducing occasional wetter weather. This may be associated with near normal to colder than normal conditions for a time. After this however, a trend towards more unsettled conditions through the middle part of March is signalled with spells of rain / showers but with some drier interludes. Rain perhaps becoming more confined to the north and west later with the south and east seeing some more prolonged settled periods. Temperatures most likely to remain around or a little above average. Whilst there are no signals for prolonged cold, some brief colder intervals continue to remain possible.

Met Office : South West England : 2021-02-27T02:14:14

Daylight : Wiltshire

Day length is dusk to dawn. Times will vary a little if there is a hill on the horizon.

It should still be light enough to read at dawn and dusk, so there will be enough light for walking even earlier (later).

Moonlight : Wiltshire

Notes

• The moon's phase or fracillum (percentage of the moon illuminated) doesn't vary much with location.
• A full moon is not just bigger, its much brighter. A half moon ('50%') give less than 5% of the illumination of a full moon. You can walk with a half 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
• Of course, you need a cloudless night as well!
