The Lowdown
Alright, let me break it down. We're looking at a pretty grim stretch ahead. For the next two weeks, there's just not much to get excited about. I'm talking about a long dry spell with nothing worth paddling out for, especially for the first several days.
Our only option is Fortress, a reef break that can work for novices when there's swell, but it's just not happening. The water is hanging around a notable 68°, which is about 3° colder than usual for this time of year, so it's a bit chilly.
The first possible glimmer comes on Saturday, August 1st, in the morning. There will be a tiny 3ft swell, coming from the S. The wind is completely glassy – you can't ask for cleaner conditions, which is a big positive. Even so, the combined wave energy is weak. The report calls it "surfable waves but very ordinary conditions," and I'd agree. It's not going to be a standout day. The shape will be poor and it’s a safe size for learners, so it’s only worth it if you're desperate to get wet.
Then on Monday, August 3rd, there's another small window. Another 3ft swell from the SSE with glassy conditions in the morning. Similar story: weak energy, and once again, it's surfable but very ordinary. Both of these days will see clean conditions but the lack of swell size and energy means the waves will be weak and unimpressive.
The crowds at Fortress come "often", so you might have company for these tiny waves.
After that, things go completely flat and poor right through to the end of the forecast window. We're looking at another full week of nothing but onshore winds and tiny, junky waves. It's a dead run. Looks more like a kite-surfing week than a surf week.

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.
