The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Fortress.
First off, the water’s running a bit colder than usual for this time of year, sitting at 69° with a 2° anomaly. So, a touch fresh, but nothing a good wetsuit can’t fix.
The next week and a half is pretty grim, to be honest. We’ve got a long stretch of small, short-period windswell and messy winds. From Wednesday the 29th through to the 8th of August, the surf is mostly poor or just ordinary. There’s a couple of windows – like Thursday the 30th morning with a 4ft SSE swell and offshore wind, but the energy is weak (193) and the conditions are just ‘surfable’. Friday morning the 31st is similar with 3ft and clean conditions, but again, very ordinary. There’s a glassy morning on Monday the 3rd of August, but the swell is tiny at 3ft. It’s a real waiting game.
Now, hold onto your board, because things finally wake up on Sunday the 9th of August. We’ve got a proper SSE groundswell arriving at 4ft to 4ft with a long 11-second period, and the wind goes offshore from the NW. The energy jumps up to 361-411 (moderate), and the report says it’s good surf conditions. That’s the first real standout.
But the real gem is Monday the 10th of August. The morning is the pick of the whole 16 days. Fortress sees a solid 6ft SSE swell, with a very long period of 13 seconds, and it’s clean with a light cross-offshore breeze. The combined energy hits 1018 (strong), and the report says it’s excellent for experienced surfers. That’s expert territory at over 5ft. The swell direction from the SSE is spot on for this exposed reef break. The long period will mean proper groundswell lines, but on a reef, that’s usually a good thing for shape, just watch for bigger sets. It’s a fairly consistent spot, but crowds are often there, so get in early.
The rest of that second week drops off. Tuesday and Wednesday the 11th and 12th still have some size around 4ft to 5ft and long period, but the winds go cross or cross-on, and the quality drops. The energy is still moderate to strong (418-524), but the wind kills it. After that, it fades into small, short-period mush through the 13th.
So, the clear winner is Monday the 10th of August. That’s the one to circle. Sunday the 9th is a solid warm-up. Everything else is either a flat spell or a messy windswell.
Rusty out.

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.
