Met Office Forecast

South West England

Dry and turning chilly in places tonight.

This Evening and Tonight:

It will stay largely dry with occasional clear intervals overnight, especially further east, but overall there will be quite a lot of cloud. Less cold than many recent nights, but still cold enough for a touch of frost in places. Minimum Temperature 2C.

Wednesday:

Quite a cloudy start, but dry with some hazy sunshine in places. Scattered showers will develop through the morning, but still with the odd sunny spell. Feeling warm. Maximum Temperature 17C.

Outlook for Thursday to Saturday:

Fine and dry throughout, with plenty of sunny spells and fair-weather cloud. However, brisk winds are likely, with gales possible. Becoming a bit warmer again in shelter from the wind.

Day 6-7 and Week 2:

A settled regime will likely be in place across much of the country at first with high pressure likely to be centred to the west or northwest of the UK during this time. However, there is the threat of some rain and a few showers in the North and East. There's a small chance more unsettled conditions with heavier showers could move up from the south to impact southern areas. There are the continued threats of rural frost and patchy fog where winds fall light. Temperatures become quite uncertain depending on where the high resides, particularly in the east where temperatures are likely to struggle above average. Warmer days are most likely to be further inland towards the south and west.

Week 3 and 4:

Confidence is low for this period as is typical of spring. The UK will likely see spells of fine, dry weather at times with fair-weather cloud and plenty of sunny spells, as well as an increased likelihood of more unsettled periods when compared to April. All areas expected to see showers or longer spells of rain at times. Temperatures are likely to be close to the average for the time of year, with the possibility of some warmer spells.

Met Office : South West England : 2021-04-20T18:48:18

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!
