How bad does the Bay of Biscay get on the Portsmouth to Bilbao ferry? Heard mixed things about the waves out there. Dont want to get Seasick
The Bay of Biscay is unpredictable, especially in autumn and winter when Atlantic storms can bring high waves and strong winds.
On the Portsmouth to Bilbao route, the ferry crosses this open stretch of water, which can be rough at times. However, modern ferries like those used by Brittany Ferries are equipped with stabilizers to reduce motion. If you’re prone to seasickness, book a cabin midship (where movement is less noticeable), and consider taking motion sickness medication in advance.
Summer crossings tend to be calmer, but rough seas are always a possibility in the Bay of Biscay.”
