The Lowdown
Alright, let me tell you what I'm seeing for the next couple of weeks. To be honest, it's a bit of a rough stretch for the Rivermouth. The whole 16-day window is pretty much a write-off for a decent session. The swell is coming from the right direction, NW, but the wind is stubbornly cross-onshore or onshore the whole time, and that's just killing any chance of clean waves. The swell energy is mostly moderate, with readings like 239, 327, and 537, but it's all just too messy.
The swell does get big, but it's not good news. From Monday, July 28th, the swell is pushing over 8 ft and hitting 10 ft, with a combined energy climbing into the strong range, 1279, 1402, and even 1622. That's expert-only territory, and with the wind still cross-onshore, it's just a lumpy, choppy mess. The period is short, mostly 7-8 seconds, so there's no groundswell power to save it. By the time we get to Monday, August 3rd, the swell is predicted to be too big for this break, hitting 12 ft with a huge 2390 or 3681 energy reading. That's not surfing, that's a washing machine. The last day, Tuesday, August 4th, is the same story.
So, there's really nothing to get excited about here. Not a single standout window. The wind just isn't your friend. For a spot that's already inconsistent and only really works with a clean NW swell, this is a classic blank run. You're better off doing something else for the next couple of weeks.
