I have been down in May and November for several years. I have "enjoyed" 6 straight days of rain in November. On average, the weather is more settled in May. The loss of the north swell in May means the bubbly pool is quiet.

While many here have said that May is quiet, that is generally correct. The only exception that I am aware of is when the MIT MBA trip is on.

This affects space at some anchorages as well as ferry availability.
