Alright, Rusty here. Let’s break down what Fortress has for us over the next couple of weeks.
To start, it’s dead quiet. From Tuesday the 7th all the way through Friday the 17th, we’ve got nothing worth talking about. That’s 11 straight days of tiny, messy, or completely flat surf. Just leave the board in the car for a while.
The first real chance of a wave comes on Saturday the 18th of July. Saturday morning we get a south swell pushing in at 6ft, coming from the south with a 9-second period. The combined energy hits 437, which is moderate, and with a light breeze and clean conditions, this is the clear standout of the entire outlook. Fortress is a reef break, exposed to the south, and at this size it’s going to be good. That said, at over 5ft, it’s getting a bit big for beginners. The water temp is right around average for this time of year, about 69°.
The afternoon on Saturday turns ugly as the wind picks up onshore, so be there early.
Sunday the 19th morning is another good one. The swell holds at 5ft from the south, period at 10 seconds, energy around 480, and light north-west winds. Clean again. The afternoon gets a bit cross-off and less perfect, but still rideable.
Monday the 20th sees the swell dropping to 4ft, still from the south, with moderate cross-off winds. It’s surfable but not a standout.
After that, it’s back to small, weak stuff. Tuesday the 21st has a glassy morning with 3ft waves, but the energy is very low (97), so it’s just ordinary.
Bottom line: Saturday the 18th morning is the session to aim for. Sunday morning is solid too. The rest of the two weeks is mostly a write-off.
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.
