The Lowdown
Alright, Rusty here again, looking at the same Fortress picture in feet and miles. It’s a rough one, folks. Over the next 16 days, we’re looking at a whole lot of nothing. The first few days are flat and ugly, with swell barely hitting 1 ft and weak energy readings around 23. You’re not missing anything.
Monday the 31st of August and Tuesday the 1st of September are just as poor, with tiny, bumpy surf. There’s a bump on Wednesday the 2nd of September—a 6 ft swell from the ESE—but it’s a short, 6-second period, and the wind is howling at 25 mph cross-on with rain. The combined energy hits 216, but it’s just a messy, choppy mess.
The only real highlight is the morning of Friday the 4th of September. We’ve got a clean 2 ft swell from the ESE with a 16 mph offshore wind out of the NW. The combined energy is a weak 61, but the conditions are clean. The water temp is about 70° with a normal anomaly. For a beginner reef, that’s your best shot, but it’s still a small, marginal session. After that, it’s back to tiny, wind-blown dribble all the way to the 14th.
This is a dead period. Not much to chase. If you’re keen, the Friday morning might give you a few little ones, but I’d wait for the next forecast update. Things can change.
Rusty.

Information about the Fortress Surf forecast
The above surf forecast table for Fortress provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Fortress can be found by selecting the local surf guide option on the grey menu. Our Fortress surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Fortress) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. 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 Fortress 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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
