Ive done a few deliveries south in November through Biscay, and its a crap shoot. Lows spiral in from finnesterre making it tricky to get a good window, all the way to Bayona.
we are approaching the autumnal equinox , and thats in my opinion a bad time of year. ( 2 weeks either side),
I would agree, if at all possible head
for Bayona, but again getting round the corner can be very tricky,
Furthermore in any large swell, a lot of the portuguese coast can be a no go, personally Id prefer to be 30+ miles offshore
given a choice.
You need to be comfortable with your heavy weather abilities and boat
. If not one option is to coastal hop, taking a much longer time, with options of sheltering in Gijon, or Coruna, waiing for a gap to dart to Bayona. ( Coruna is a long way in though).
Tricky Tricky time of year, windows are closing best of luck
