For Cambria (Leffingwell Landing)

https://magicseaweed.com/Cambria-Surf-Report/261/One or two stars= Calm seas are more than likely. 3 stars or more, probably too rough for a newbie, or most, in my opinion.
To get a good understanding of what these forecasts really look like in action, look at a forecast and then find a beach camera one of these locations. Now you will have a real-time understanding of the relationship between forecast and actual ocean conditions. I google search "morro bay beach camera" or Cayucos, Cambria, Pismo, etc.
So if you want to fish Friday morning, start looking at the forecasts and videos (videos during the same time you plan to fish) earlier in the week.
Finally, regardless of weather, try and find someone to fish with. The older and wiser, the better!
