The Lowdown

Alright, this is Rusty, and I’m looking at the forecast for Fortress.

Honestly, I gotta be straight with you—this sixteen-day run is a tough watch. The swell is tiny and weak, and the wind is all over the shop. There’s just nothing to get excited about for the first week and a half. You’ve got a long gap from today until around the 15th of August where the surf is barely a whisper, with heights mostly under 3ft and the combined energy barely cracking 100 (59-111). The wind is cross-off or cross at best, but the waves are just too small and gutless to ride.

There’s a tiny window on the morning of Monday the 12th of August. The wind is offshore from the WNW at 15 mph, keeping things clean, and the swell is 3ft from the SSW (6 seconds). The combined energy is only 57, so it’s weak. It’s surfable for a beginner on a longboard, but it’s not a standout.

The only real pulse in the whole forecast comes way down the line on Thursday the 20th of August. The swell jumps to 7ft from the ESE, with a period of 8 seconds. The combined energy hits 598, which is the only real punch of energy in the whole outlook. But here’s the catch – the wind is onshore and cross-onshore, and there’s a risk of thunderstorms. It’s going to be messy and lumpy. This is not a beginner wave; at 7ft with that chop, it’s only for experienced surfers who are happy to wrestle a bit. It’s the best of a bad bunch, but "best" is a relative term here.

The rest of the period after that is just back to tiny, weak slop, with the wind swinging around again. It’s a pretty bleak run for Fortress.

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.
