The Lowdown
Alright folks, Rusty here. Let me tell you straight up, it’s a tough run coming in for Beau Vallon Beach. The whole 16-day window is a write-off for any decent surf. We’ve got consistent swell, no doubt, but the wind is a total killer. It’s locked in from the SE and SSE, blowing cross-shore and cross-onshore, and it’s not letting up. The water is a touch warmer than normal for this time of year, sitting at 81°F, but that’s about the only nice thing I can say.
Right from the start on Monday the 27th, we’ve got a 6ft SE swell coming in with a period of 10 seconds, giving us moderate wave energy (602), but the 19 mph cross-shore wind has got the ocean looking like a washing machine. The "poor surf conditions" tag is bang on. This pattern just keeps rolling through the week: Tuesday the 28th, Wednesday the 29th, Thursday the 30th – all cross-shore, all lumpy, all poor. The swell drops slightly on Thursday to 4ft, but the wind is still a mess.
Heading into the first week of August, the wind doesn’t shift. Friday the 31st sees a 5ft spike with a short, weak 6-second period (285 energy), but it’s a cross-shore mess. Saturday the 1st of August pumps a 6ft swell (563 energy) but again, 22 mph cross-shore winds ruin it. This pattern of moderate swell and ripping cross-shore wind is relentless. We get a little break in the wind speed on Monday the 3rd of August, dropping to 9 mph, but it turns cross-onshore and choppy. The swell is only 4ft.
Things get a bit more interesting from the 6th of August onward, with swell heights pushing over 7ft and even hitting 8ft on Tuesday the 11th of August. The wave energy jumps into the strong zone, with readings over 1000. But for a beach break like Beau Vallon, with these cross-shore winds, that kind of size is just a messy, lumpy, and dangerous wall of white water. The period is mostly around 9-10 seconds, which is moderate, but the wind just won’t cooperate. The only session that even gets a marginal rating is Thursday afternoon the 6th of August, with a 7ft SE swell and the wind dropping to 12 mph, but it’s still cross-shore with a chop. It’s not worth paddling out for.
Honestly, with this constant wind and the beach setup, it looks more interesting for kite surfing than paddle surfing. The swell is there, but the quality is zero. It’s a blank run of 16 days, and for this area, that’s not unusual when you get a stubborn wind pattern like this. Forecasts can change, but as it stands, leave the boards at home.

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 Beau Vallon Beach 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.
