South West Coast Path 2: Porlock to Lynton walk

Met Office Forecast

South West England

Very strong and disruptive winds with outbreaks of rain.

This Evening and Tonight:

Storm Arwen brings strengthening winds, with severe gales along coasts and over high ground overnight. Outbreaks of rain spread southwards through the night, potentially falling as snow mainly over high ground, chiefly in the east. Feeling cold. Minimum Temperature 1C.

Saturday:

Rain and snow clearing to leave an afternoon of sunny spells and scattered showers in west Cornwall. Feeling cold owing to significant wind chill in strong and gusty northerly winds. Maximum Temperature 7C.

Outlook for Sunday to Tuesday:

A frosty start to Sunday with further showers in the west, but much lighter winds. Turning cloudier and less cold through Monday and into Tuesday with light rain at times.

Day 6-7 and Week 2:

Windy day with sunshine and showers on Wednesday, possibly heavy and wintry in the north and west. Winds remaining fresh. Potential for more potent low pressure systems to develop into the weekend, bringing temperatures changing between mild and cold, with a risk of widespread frost in the cold periods. Occasionally windy. Continually unsettled through the rest of this period with spells of wet and windy weather interspersed with brighter interludes accompanied with showers. Likely the wettest conditions to be in the west and northwest, and calmer conditions in the south towards the end of the period. Often windy with a risk of gales at times, especially in the north and northwest. Temperatures likely milder than of late, with the potential for brief colder interludes between systems.

Week 3 and 4:

Overall, through this period it is expected to be unsettled and changeable with milder and wetter than average conditions for most, bringing a risk of stormy conditions. Perhaps turning more settled in southern regions for a time nearer the start of this period, which will increase the risk of frost and fog when skies clear overnight. Temperatures on the milder side for much of this period, but some short lived colder spells are possible.

Met Office : South West England : 2021-11-26T15:21:19

Daylight : Exmoor

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 : Exmoor

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!
