The Lowdown
Alright folks, it's Rusty here. Let's get into it. To be straight with you, the next couple of weeks are looking pretty grim for a proper paddle. We've got a real dry spell coming up, so don't get your hopes up for anything firing.
The first real glimmer of something we can actually call surf shows up on Thursday, July 30th down at Fortress. It's a reef setup, so it needs a bit of direction to come together. The water is sitting cold at 68°, which is a bit colder than normal for the time of year, so you'll want the thick rubber.
Now, for the standout. The best of a bad lot is that Thursday, July 30th. We'll see a morning pulse of swell from the SSE pushing around 3.3 ft, and more importantly, the wind is going to be ripping offshore from the WNW. That's clean, lined-up conditions for a reef. The combined energy is moderate at best (409), but with clean faces, it'll be the best you're gonna get. A bit of period at 9 seconds gives it some shape. The afternoon cleans up more with a 4.3 ft ENE swell and cross-offshore breezes. It's not huge, but it's rideable.
After that, it's back to the doldrums. Friday the 31st has some tiny clean swell, but it’s ordinary. Saturday, August 1st kicks off with a tiny 1.6 ft glass-off, but it’s gone by the afternoon. There’s a brief window on Monday, August 3rd with a glassy 3.9 ft SSE swell in the morning (combined energy of 193) but the afternoon gets chopped again.
The second week, from August 4th onwards, is a bust. Mostly small, weak swell with cross-shore or onshore winds. The only other thing to note is the very end of the outlook, Sunday, August 9th afternoon. It’s showing a 4.9 ft SSW swell with a clean cross-offshore wind from the WSW (combined energy of 136). The period is only 6 seconds though, so it'll be a bit weak and disorganised. It’s a long-range call, so treat it as promising but not locked in.
So, if you're hanging for a wave, circle Thursday, July 30th. Everything else is a wash.

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.
