The old site is gone. The new one is simpler and uses a more reliable database of core buoy data so the forecast is always up-to-date. We've also designed the new site for better mobile access.

Why they're better:

SURFcasts.com goes one step beyond what traditional surf forecasting sites do: instead of just giving you the information that is pulled constantly from weather buoys, we process it so that the "Score" you see for each break takes into account the important conditions that make waves surfable. Traditionally, the data that comes from weather buoys is geared for mariners and fisherman who are interested in the conditions far offshore, not at your favorite beach break. Therefore the core data that you might read off of a weather buoy might not give you a good idea of actual conditions where you want to go surfing.

That's where our "formula" comes into play. We've created a way of quantifying the important data that comes from these buoys so that the conditions at any moment in time can be evaluated for their 'surfability.'

Every report we generate is unique by spot. This means that even though two breaks might both have a 10 ft. swell and a 12 second wave period, they probably won't have the same score- one might be scoring a 8 while the other is only getting a 4. Even though the 8 will almost definitely be better, if you were to look at just the data they would look almost identical.

How you should use them:

Like many things, we think SURFcasts improve with time. Actually, what we're trying to say is that after checking your break's SURFcast a couple of times you will start to get an excellent idea of what the number actually means. Even though we try to sum it up for you on our Score Chart, to get the most out of any forecast require a little local know-how. After a bit of getting used to it's fairly easy to figure out how much better an 8 is than an 4 at your favorite spot.


The core data from which our reports are generated comes from NOAA (National Oceanic & Atmospheric Administration) and specifically the NDBC (National Data Buoy Center).
