I have skied and surfed in the same day several times. Mt. Baldy has legit terrain, it's not Jackson or Squaw, but it has some pitches that maintain maybe 35 degrees for 1500 vertical. Many years the good stuff does not open, but this year it was for much of the year. I go to Mammoth every other weekend, but this year was great, because every weekend I did not go up I could ski some good, slushy steeps at Baldy.
Baldy is only one hour from Newport Beach, so I have skied until 3, then gone back and gotten a spring evening session at Newport many times.
The first time I surfed/skied in the same day was mountain high and shitty waves, so it was just to say I did it. This year I got some fun slush lines down to the parking lot at Baldy, and then pretty good surf in Newport.
I have yet to get a powder day and Baldy AND surf, that would be awesome.
Can you surf/ski in Oregon? I would imagine that would be another place to do it.
