Forecast For Abersoch : Saturday 20th April, 2024 - Issued at 8.00am by Chas




Headline Summary: Fine Weather!!!

Bore da - Good morning from Abersoch... The sunshine has returned, with clearing skies on Friday afternoon, followed by a clear night and it has dawned clear and cold here in Abersoch and mostly clear skies are expected through today. There was just a few spots of grass frost on the golf course at sunrise this monring, but the sunshine already feels lovely with very little breeze. There are some mixed messages this morning regarding the wind's behaviour during the day, but it may stay light and variable at times, so it should become noticeably warmer. If the breeze does pick up, then we wil get more of an influence from the colder sea, so it won't feel as warm. Today also sees the first edition of the She Ulta marathon, with over 500 women taking part in a 30 mile foot race which started at 7am in Pwllheli and finishes on the main beach here in Abersoch...



Today: Saturday: Beautiful and quiet start to the morning. Thereafter, mostly fine with sunny spells and patchy fair weather cloud. Long sunny spells are expected. Some uncertainty regarding the behaviour of the breeze (as mentioned above), but it may stay light and variable in direction, so there is a reasonable chance of a noticeably warmer feel, especially in sheltered sunny spots. Cold overnight with clear periods and light winds, with perhaps a touch of grass frost in some locations.


Sunday: Fine with sunny spells and variable amounts of cloud. Those cloud amounts are uncertain, but we should see hazy sunshine at times during them. Light winds in the morning so feeling quite warm in any sunny spells after a cold start to the day, with perhaps a northerly breeze picking up in the afternoon.


Monday: Cloud amounts are very uncertain on this day, so it is difficult to envisage how much sunshine there may be, however, some charts suggest plenty of cloud throughout. Low risk of a shower in the cloudier spells. Not much breeze in the morning with perhaps a northerly breeze picking up in the afternoon. Feeling chilly under any cloudier spells.


Tuesday: Potentially mostly dry and fine with some sunny spells and variable amounts of cloud. There may be a northerly breeze, so sheltered spots will do best for a warmer feel.


Wednesday: Similar to Tuesday - mostly fine with a breeze from a northerly quarter.


Outlook: Probably mostly dry on Thursday with a mix of sunshine and cloudier spells. There is likely to be a breeze from a northerly quarter, but any sunny spells should feel pleasant enough. Perhaps turning unsettled for Friday / Saturday, but there is loads of uncertainty by then. Temperatures may be chilly at times.


Extended Outlook: The outlook for the period from Sunday 28th April to Thursday 2nd May ... is for a changeable period, with a mixed bag of weather.
