South West Coast Path 1 : Minehead to Porlock walk

Met Office Forecast

South West England

Heavy rain likely, especially overnight.

Today:

Rain will quickly spread northwards from the south coast during the morning, including some heavy bursts, most likely in Dorset and Wiltshire. The rain will clear for at time in the afternoon but it will stay rather cloudy. Maximum Temperature 17C.

Tonight:

Rain and showers will develop overnight across much of the region. The heaviest showers are likely in Dorset and Wiltshire, and here, thunder, hail and localised flooding are possible. Minimum Temperature 12C.

Wednesday:

Early rain, perhaps still heavy during rush hour, will gradually clear eastwards during the day, to leave warm sunshine, particularly across Devon and Cornwall, where a breeze will develop. Maximum Temperature 19C.

Outlook for Thursday to Saturday:

It will be breezy and less warm on Thursday with sunshine and a few showers. Friday and Saturday will probably be dry with light winds and spells of warm sunshine.

Day 6-7 and Week 2:

On Sunday most places will start fine, bright, and dry and remain so through much of the day, especially in northern and eastern parts. Temperatures will recover to normal or be locally warm. However, for southwestern and western parts heavy rain and some strong winds should arrive during the day as low pressure moves towards the UK from the southwest. Rain is likely to spread northward and eastwards into Monday bringing unsettled weather more widely for the start of the next week. As we head into late June there are signs that high pressure may become more dominant, bringing a chance of settled and warm weather with temperatures mostly near normal. However, by early July we may see a return to greater influence from Atlantic again, although confidence is low.

Week 3 and 4:

During the first half of July predictability becomes very low, with mixed signals. However, at present the favored solution is for increased Atlantic mobility through this period, bringing spells of unsettled weather to the UK, generally associated with low pressure systems, interspersed by more settled anticyclonic regimes. This will likely mean that showers or longer spells of rain will affect northwestern parts of the UK, whilst the south and southeast will see more in the way of dry weather: although some thundery outbreaks are likely in the south and southeast as is usual this time of year. Temperatures through the period will probably near or slightly above average.

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!
