Forecast For Abersoch : Wednesday 31st January, 2024 - Issued at 6.55am by Chas



Note: No forecast on Thursday due to illness. Below is Wednesday's update.



Headline Summary: The Cloud & Wind Returns.


It was great to see some sunshine again on Tuesday, but it did get quite chilly for a time early in the evening, however, the cloud has returned overnight on a southwesterly wind and that is today's theme - cloud and wind... and the wind is expected to gust to gale. A cold front will bring some rain later in the day, before we see a quieter day on Thursday.


The reason for today's wind is a deep area of low pressure, which is expected to be centred to the north of Brtain at midday. That low will be out of the equation for Thursday - hence the potential for a quieter day, but we will see breezier weather on Friday. At the moment, the weekend is looking like seeing plenty of cloud and we could see a bit of rain too, however, the details are chopping and changing a bit...


Today: Wednesday: Strong to gale force southwesterlies today, feeding in plenty of cloud. The wind will make it feel chilly, but temperatures may get to 10c. Some rain arriving during the second half of the afternoon and lasting into the early evening with a cold front moving through at it winds may be very gusty for a time around the rain. Clearer from the second half of the evening onwards and the wind should veer to the northwest and ease. Cold overnight, with sheltered spots perhaps seeing temperature close to frost levels.


Thursday:Variable amounts of cloud and some brighter periods are expected, with a bit of a westerly then southwesterly breeze. Not feeling particularly mild during the day, but temperatures may rise to 10c during the evening and overnight period, as milder air moves in. Low cloud may move in overnight too.


Friday: Mostly cloudy and mild with strong southwesterly winds. Chance of a bit of drizzle, with low cloud potentially reducing visibility over the higher ground. Temperatures may raise above 11c by day and stay at 10c overnight.


Saturday: Cloudy and breezy from the west-southwest. A spell of drizzle or rain is likely at some point - timings to be confirmed. Mild by day and night.


Sunday: Breezy from the southwest, with the cloudy and generally mild theme continuing.


Outlook: The cloudy and mild, southwesterly weather may continue from Monday to Wednesday, with strong southwesterlies at times. We may see brighter spellls, but also a couple of wetter spells too.


Extended Outlook: The outlook for the period from Thursday 8th February to Monday 12th February ... is for a generally changeable and breezy period. Potentially mild for most of the time. Perhaps chillier later in the period.
