Met Office Forecast

South West England

Fine today with sunny spells. Feeling cool.

Today:

After a cold start today, it will be fine with plenty of sunny spells. Winds easing throughout the day, though staying breezy in coastal areas. Feeling generally cool but pleasant in the sunshine. Maximum Temperature 16C.

Tonight:

Largely clear skies tonight but with some cloud and a chance of rain in the west. Another cold night with frost possible in rural areas. Minimum Temperature 2C.

Monday:

Cloudy on Monday, though with some sunny spells possible in the morning. Outbreaks of light rain are likely but it will generally be warmer and less windy than the weekend. Maximum Temperature 18C.

Outlook for Tuesday to Thursday:

Mostly dry with sunny spells on Tuesday. Turning increasingly unsettled and windy from Wednesday with rain, sometimes heavy, moving in. Similar on Thursday, with only brief dry interludes.

Day 6-7 and Week 2:

An unsettled period, with plenty of showers and some occasional longer spells of rain across much of the country, the heaviest and most widespread areas likely in the west or northwest, and only limited drier interludes. Often windy, with a risk of gales at times (potentially severe), particularly around coastal regions and within areas of more significant rainfall. With time, northern parts of the UK may tend to become drier and more settled overall, with low pressure systems tending to track further south. Feeling cold, especially so where there is persistent rain and strong winds. Frost is possible at night in any calmer period, becoming increasingly likely for the northern half of the UK later in this period.

Week 3 and 4:

A potential change in the weather is anticipated around the middle of October. Whilst further rain and strong winds are likely at times, spells of fine and dry weather could become more widespread and long-lived. At night, these calmer conditions could allow frost and fog to form more readily. At this time of year, there is potential for fog to linger well into the daytime. Overall, temperatures probably recovering close to the seasonal average for mid-October.

Met Office : South West England : 2020-09-27T01:45:18

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!
