Saturday - Rain looks like it could be heading north but may only effect SW Wales and the SE could be left dry, hopefully. Otherwise it is looking like being a bright, dry day with a mostly southerly wind of 15 - 20mph. So your slope options will be Back of Wrecker at the Bwlch or the coastal slope at Southerndown.
Sunday - is looking like a mixture of sunshine and showers with a southerly wind decreasing slowing during the day from 20 - 30 mph at 10am down to 12 - 18 mph by 4pm. So your slope options are the same as for Saturday.
I am unable to fly on Sunday but I am intending heading up to the Bwlch on Saturday for about midday, as my new L39 Albatross PSS model needs its maiden flight.
So whatever you are doing this weekend, happy flying.
