Kintbury to Great Bedwyn walk

Met Office Forecast

South East England

Cloud increasing with mist and fog. Locally bright Wednesday.

This Evening and Tonight:

Evening clear spells will allow mist and fog patches to form. Cloud will increase overnight with intermittent drizzle possible later. A frost is possible in places for a time. Minimum Temperature -3C.

Wednesday:

Mainly overcast, with mist and fog patches, perhaps the odd spot of drizzle at times. Brief bright intervals are possible with light winds. Feeling chilly. Maximum Temperature 9C.

Outlook for Thursday to Saturday:

Often cloudy with occasional sunny intervals, and frost and fog patches during the nights, fog locally slow to clear by day with light winds. Becoming windier on Saturday.

Day 6-7 and Week 2:

Sunday will turn more unsettled for most, with bands of rain moving southeast across the UK, accompanied by a strengthening wind. Heavy showers behind fronts could also bring some wintry precipitation to the hills of the north. Next week looks likely to remain unsettled, with Atlantic fronts making their way southeastwards across the UK. The north and west are likely to see the wettest and windiest spells, with the occasional risk of snow on higher ground. The south and east should stay slightly more settled, though there will still likely be some wet and windy periods. Any settled spells between fronts will lead to some brighter conditions and isolated overnight frosts, but these will likely be short-lived. Temperatures generally around average in the north and just above in the south.

Week 3 and 4:

Through the first half of this period, the mobile wet and windy regime looks set to continue. It seems probable that the most unsettled conditions will gradually transfer further north, leaving a more traditional northwest/southeast split. There are signs that through the middle of February, that a more settled, anticyclonic pattern will begin to affect the southeast. These settled conditions may gradually move further northwest to influence much of the UK for a time. This would bring drier weather for all, with an increased likelihood of fog and frost. Unsettled spells of strong winds and rain are still likely from time to time, but mainly in the northwest. Temperatures are likely to be around normal, with a large diurnal variation, if the more settled regime was to take control.

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, and, (ii) if there are hills on the horizon.
• Of course, you need a cloudless night as well!
