You want to look at swell rather then wave. Swell is larger ocean effect. Waves are the more acute wind influenced effect. Waves are more wind based and aren’t really bothersome at most anchorages. Swell can be very bothersome when is rocking your boat all around.
In a big north swell avoid Honeymoon, Caneel, etc on St John. Maho and Francis are good. In south swell avoid most southern anchorages. Everything feels worse on a mono vs cat.
Instead of windguru, check windy.com
(Just my opinions and observations)

(Just my opinions and observations) In a big north swell Honeymoon and Caneel would be a better anchorage than all the bays from Hawksnest to Francis Bay. Water lemon Cay on the east side will be calm along with all the anchorages on the south shore.

Can someone describe what a “big” north swell might look like in swell height? When is it too small to even worry about from any direction? It’s relative sailor to sailor. I don’t like caneel in any swell over 1 meter. That’s fine in maho. In my mind in the USVI “Big” swell is 1.3-2 meters. This is daily stuff, not talking storms nearby, etc. The swell isn’t as bad if the wind stays up overnight but when the wind settles to only a few knots the swell just rolls the boat all over. Most of the time swell is under 1m. I base much of this knowing that you can just plan your trip differently knowing the conditions. If I’m sitting in caneel knowing i could be comfortable 40 minutes away in maho I would much prefer to be there.
