Met Office Forecast

South West England

A bright and breezy day, with sunny spells and showers.

Today:

Bright and breezy, with a mixture of sunny spells and scattered showers. Some of the showers could be heavy, particularly towards the Bristol Channel at first, though most places will probably stay dry. Feeling a little cooler compared to yesterday. Maximum Temperature 21C.

Tonight:

Clear spells and scattered showers continuing through the evening and overnight, particularly across the west of the region. Showers potentially heavy and thundery towards the Bristol Channel. Staying breezy. Minimum Temperature 9C.

Monday:

Another day of sunny spells and scattered showers. Some of the showers could be heavy, though many places will stay dry altogether. Showers and the breeze tending to ease later. Maximum Temperature 21C.

Outlook for Tuesday to Thursday:

Sunshine and showers on Tuesday. Similar on Wednesday, though a band showery rain may move in from the west later. Turning drier and brighter on Thursday, with some warm sunshine.

Day 6-7 and Week 2:

Thursday will see further spells of rain and perhaps stronger winds affecting northern parts of the UK, with the south more likely to remain largely dry with sunny spells. The end of the week and into the weekend is uncertain at this stage, but will probably see the unsettled weather continuing, mainly across the north and northwest, with drier and brighter conditions elsewhere. Temperatures will recover to near or above average by day. During the remainder of the month high pressure is likely to remain close by to the southwest bringing periods of settled and warmer conditions, especially across southern areas, with perhaps the chance of some thundery showers moving up from the near continent. The north and northwest may see further spels of wet and windy weather at times.

Week 3 and 4:

Confidence remains rather low during this period. However, there are signs that high pressure will increasingly dominate the weather across the UK. Southern areas are most likely to see the driest and sunniest weather at first, perhaps with some lingering wet and potentially windy conditions affecting the north. However, longer spells of dry and sunny weather may occasionally develop across all parts. Temperatures are generally likely to be warmer than average, although there is little indication of anything exceptional at this time.

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!
