The Lowdown
Alright folks, Rusty here. Gotta be straight with you on this one for the Fortress.
Alright, let’s look at the whole 16-day window. Honestly, it’s a pretty grim run for the Fortress. We’re looking at a long, dry spell for decent waves. The first three and a half weeks of the forecast are a write-off if you’re after a proper session. The combined swell energy stays weak, barely cracking triple digits for most of it, and for a lot of days it’s down in the 20s and 30s, which is just pathetic. You're looking at a lot of cross-shore and onshore winds, lumpy chop, and tiny swell.
The one tiny glimmer in this whole run shows up way down the track, on Monday morning, the 10th of August. The Fortress sees a bit of a lift, but it’s barely surfable. We get a clean, glassy morning with a 2ft SSE groundswell running on a decent 10-second period. The combined energy is still weak, only 81, but at least the wind is completely off the cards. That’s the only time in 16 days you might get a clean wave face, but it's tiny. After that, it drops right back into the doldrums, with onshore winds and a return to poor conditions.
For the rest of the run, the surf quality is just poor. The swell direction is mostly from the S or SSE, which isn't the optimum SE direction for this spot either. Even the slightly bigger pulse on Thursday the 30th of July, with 4ft from the SSE and a brief offshore wind, is only rated as 'marginal' and the water is a bit colder than normal for this time of year. It’s just not worth paddling out for. If you’re a beginner, stay home. The conditions are not inviting.
So, the verdict is: there’s nothing to get excited about. The long-range promise on the 10th of August is a tease, but that's it. This is one of those stretches where forecasts can change, so keep an eye out, but for now, you’re better off finding something else to do.
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.
