Rincon, Puerto Rico Surf Forecast – August 9, 2021

Hurricane Season 2021 is heating up – surf?

The short answer is yes, most likely. Unfortunately it’s a yes for most of the island outside of Rincon. A storm passing below or right on top of the island is more of a east coast or north coast type of event. If we get some decent south winds and enough of a drop in pressure, the north facing beaches in Rincon just might be rideable. Your summer time spots are going to be working better though. But hey, at least there’s something to report. We’ve been stuck in a super flat pattern for quite some time now. It’s good to have something watch for this week. Let’s see how it develops. I’ll update as soon as I see something more concrete lining up.

Using Automated Forecast Tools:

Remember that no matter what a computer model tells you, what you see on the beach might be completely different. That's why i go take pictures of the beach every day. These tools help give an idea of what to expect, but weather prediction is not always exact especially the further out you try to forecast. Surf forecasting takes into account the general correlation between past weather data and resulting surf conditions. Another thing to keep in mind is the difference between actual swell height and the face height of the rideable wave it creates. For example. When the waves are forecast to have a 6ft swell at 13 seconds or higher with a NW angle we normally get waves that most people would call double over-head on sets. Swell angle is also important, especially for shorter period swell (9-11 seconds). For example 3ft at 11 seconds from the NW will make a bigger wave than 4ft at 9 seconds from the NE. Normally longer period swell (13+ seconds) will be more powerful and keep the surf size a little better even if the angle isn't a direct hit to Rincon. Generally any swell less than 9 seconds is super weak here in Rincon unless it has a lot of west in it. Also, most NE swell under 12 seconds is weak and mushy. 2ft at 8 seconds is generally small to flat. ENE swell will almost never make it into Rincon unless it was something like 10ft at 18 seconds from the ENE.
