The Lowdown
Alright folks, Rusty here. Let’s have a look at what we’ve got on the cards for the next couple of weeks.
To be straight with you, it’s a tough stretch ahead. The first few days have some waves, but the wind and conditions just aren’t playing ball. The real standout comes later, so don’t get too disheartened.
Things kick off on Sunday the 26th of July with a small 3ft swell from the ESE, but it comes with a moderate cross-onshore breeze making it choppy. The combined energy is weak at 91. Monday and Tuesday look similar with weak energy (65 down to 43), and the same onshore and cross-shore wind issues. Wednesday the 29th sees the swell bump up to about 6ft from the east, carrying moderate energy at 335, but with strong onshore winds and heavy rain, it’s a write-off. Thursday the 30th cleans up a bit with a cross-offshore wind, but the swell is mixed and the wind is strong at 28 mph, so it’s not really a surfer’s dream. The water temperature is about average for this time of year.
Now, for the one true bright spot. Friday the 31st of July, early morning at Fortress. We get a clean 3ft groundswell from the SSE with a 9-second period, pushed by a gentle offshore breeze from the WNW at 9 mph. The combined energy is a moderate 132, and it’s the first time we see a “gentle offshore and clean” report. The crowd at Fortress can be an issue, so get in early. If you’ve got a free morning, this is your best shot.
After that, it’s back to ordinary. Saturday the 1st of August has a glassy start with a 3ft south swell, but the energy is low at 95 and it’s a short period. The rest of the first week and into the second week is a mix of small swell, cross-shore winds, and onshore breezes. There’s a few clean slots on Monday the 3rd and Wednesday the 5th of August, but the swell is small and the winds aren’t perfect. The best of a bad bunch might be the morning of Wednesday the 5th, with a 5ft south swell and a clean cross-offshore wind, but it’s still just a 1/10 on the wave quality. The combined energy is a moderate 165, but the period is short at 6 seconds.
Beyond that, into the second week, from the 7th of August onwards, we see the swell drop right off with weak energy and persistent cross-shore winds. Sunday the 9th and Monday the 10th are basically flat with onshore winds and tiny lumps of 1ft to 2ft.
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.
