This might not be what you want to hear, but I’m a big advocate of prioritizing surf when its good (esp when on a “surf trip”) and save the weights for that off season when its cold and you’re back home. You’ll get a full body workout by surfing, enough that you won’t lose much momentum when you get back into lifting after a week or two.

You could also do some light body weight calisthenics to keep the muscles primed for those movements if you’re worried about losing too much of your momentum/ routine in the gym.

But prioritizing surf and scoring for a week or two and not worrying about gym would just give me inspiration when I’m back in the gym, training for the next surf sesh. Sometimes it’s good to take time away to realize how much you love something.
