Met Office Forecast

South West England

A fine start, but turning cloudier from the west.

Today:

Any fog or low cloud will clear during the morning to leave a largely dry day with some sunny spells. Becoming cloudy with some patchy light rain or drizzle across Cornwall during the afternoon. Feeling warm. Maximum Temperature 22C.

Tonight:

Staying cloudy in the west with some fog over hills and along windward coasts. Clearer skies to the east where some patches of fog will form through the early hours. Minimum Temperature 11C.

Saturday:

A cloudy start with any fog patches in the east clearing through the morning. Remaining dry but rather cloudy into the afternoon, but sunny skies developing in the south later. Maximum Temperature 21C.

Outlook for Sunday to Tuesday:

Mostly dry with sunny spells on Sunday, but turning windy later with rain arriving overnight. Further showers for Monday and Tuesday these heavy at times.

Day 6-7 and Week 2:

This period will see unsettled conditions for many with low pressure systems crossing the UK. This will bring organised bands of rain, heavy at times for those in northern and western parts of the country, and in-dispersed with cooler and showery periods, as well as some bright skies at times. Drier and more settled conditions are likely across southern and eastern parts of the country, but there is still a chance that bands of rain and strong winds from the north and west could extend into these areas. The temperatures are most likely to be slightly below average for this time of the year during the start of the period but will gradually return to near average.

Week 3 and 4:

Confidence is typically low through this period. Current signals suggest the higher pressure is more likely over the south during this period, giving generally dry and settle conditions. More settled conditions may spread northwards at times. Lower pressure in the north will bring periods of showers or longer spells along with stronger winds. Temperatures most likely around or above average.

Met Office : South West England : 2021-09-24T01:06:01

Daylight : Dorset

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 : Dorset

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!
