The Lowdown
Alright, let’s talk in feet and miles per hour. Rusty here, looking at Fall Bay Reef.
Straight up, the next week is a bust. Tiny swell, short period, and the wind is mostly mediocre. We get a few mornings with cross-off or even glassy wind, but the wave height is barely a ripple. The combined wave energy stays low to moderate, but the quality is poor. From now through the end of August, there’s almost nothing worth suiting up for. It’s a dead stretch for the reef.
Now, if you can wait, there’s one real standout way out there. On the morning of Thursday, August 27th, the reef comes alive. We’re talking a 10-foot swell from the WSW with a 10-second period—that’s real groundswell power. The wind is offshore from the NW at 12 mph, so it’ll be clean and glassy. The combined wave energy is a huge 1433, which is very strong. This is serious, heavy surf. Beginners should stay far away—this is expert territory only. The spot is inconsistent, so when it lines up like this, it’s a special day. Keep in mind, this is a long-range call, so it’s promising but not locked in. When the surf is this good here, expect crowds.
The afternoon of the 27th drops to about 8 feet with a cross-shore wind, so the morning is the time.
Before that, on the afternoon of Wednesday, August 26th, there’s a pulse: about 8 feet from the SW with cross-off wind, but the period is short (7 seconds), and the energy is moderate at 752. It’s marginal and not worth the drive.
So, a long dry spell, then one proper session on the 27th morning for the brave and the skilled. That’s your shot.
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 Fall Bay Reef 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.
