Table - best surf conditions forecast for Fortress over the next 16 days.
G’day, Rusty here. Look, I’ll be straight with you – this is a tough run for Fortress. The whole 16-day window is a real grind, with almost no decent surf on offer. We’ve got a blank run from now until Tuesday the 21st of July, with nothing but poor surf conditions day after day. The swell is tiny, the wind is all over the shop, and the wave energy is weak. It’s not a stretch to say you’ll be better off doing something else.
The only glimmer comes on Tuesday the 21st of July, early morning. We’ve got a 4ft swell from the south, with a period of 9 seconds. That’s not huge, but the wind goes glassy out of the northeast, and the water temp is sitting at 66°, which is a bit colder than normal for this time of year – about 3° below average. The wave energy is moderate (281), and for a rare moment, the conditions are actually looking good. That’s the one session to pencil in if you’re desperate. But it’s a short window; by the afternoon, the wind swings and ruins it.
After that, it’s back to the same old story – small, messy, and unappealing. The swell tries to pick up again around the 20th of July with 6ft from the SSW, but it’s a cross-shore wind and choppy, so it’s not going to be clean. The following days are just a repeat of weak, wind-affected junk. Honestly, don’t hold your breath. I’d say sit this one out and wait for the next change.
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.
