The Lowdown
Alright, let’s talk in feet and miles per hour. Rusty here.
The only spot in the game is Barron Rivermouth, a point and river mouth that thrives on a solid SW groundswell. The water is about 89°F, a touch warmer than usual for this time of year.
But man, it’s a tough slog. For the first week and a half, the swell is there, but the wind is a killer. The combined energy is moderate, reading between 321 and 854, but it’s all cross-onshore chop. You’ll see waves around 2 to 3 feet most days, but it’s messy. Thursday the 14th of August morning has a brief moment of offshore wind, but it’s still tiny at 3 feet and marginal. Not worth getting excited about.
The only real standout, the one you need to circle, is the morning of Thursday the 27th of August. The forecast shows a 3-foot SW swell with a 15-second period – that’s proper groundswell. The wind is glassy. Dead calm. The combined energy hits 454, which is solid. The river mouth will handle that long period swell beautifully, giving you clean, long rides. This spot is fairly consistent, but crowds are possible, so expect a few heads out. Beginners will be fine on this size.
Everything else between now and then is a bust. The afternoons are all cross-onshore chop, and the mornings are a gamble. The last few days of August show a couple of sessions with a cross-off wind, but the swell drops to 2 feet, which is just ordinary. If you’re into kiting, the steady cross-onshore winds might be more fun than paddling out in the chop.
Rusty.

Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Barron Rivermouth may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
