Yellow Walls and Rhoscolyn can be very sheltered. I did The Sind in January; the day before we were on South Gully, Devil's Kitchen. Wind direction is important, it was blowing a hoolie in the S. Stack car park but I overheated on the route. The Met. Office is currently forecasting a N. Easterly for Saturday which would be ideal.
