The Lowdown

Right, surf’s up? ... Well, not really. I’m lookin’ at the next two weeks for Fortress and honestly, it’s a tough stretch. This is a reef setup that’s wide open to the elements, and for the vast majority of the forecast period, we’ve got junk conditions. From now through to early next week, it's a real flat spell. The energy is weak (combined swell energy values are mostly in the 30s to 60s range), wind’s messy, and the swell is just not there. You’ve got a stretch from Wednesday the 2nd all the way through to early in the second week where the best you can do is a score of 1 out of 10 on a couple of isolated mornings. Monday the 7th morning sees a tiny 2ft easterly swell at 11 seconds, but it’s a groundswell, and with light cross-off wind it’s clean, but there’s barely enough push to stand up. Then Friday the 11th afternoon gives you a similar story – clean but tiny.

It’s not until later in the second week that something shows a pulse. On Thursday the 17th morning, we finally see a push of 6ft easterly swell with a period of 6 seconds. That’s short-period windswell, so the quality likely won’t be anything to write home about, but we get a gentle offshore wind out of the west, so the surface could be clean. The combined energy (186) is moderate, so there's a bit of grunt there, and that offshore wind will be a major positive, making it at least rideable. It’s still pretty small for this kind of exposed reef – not really a standout, but it’s the best we’ve got in the whole outlook. For the first break I mention, water temps are about average for this time of year.

Look, if you’re a kite surfer and there’s any decent wind, this open setup might be fun, but for a standard paddle surfer, this is a bleak 16-day forecast. The odds of a blank run like this are more normal for the area when the swell window is quiet. Don’t hold your breath – forecasts can change, but right now, I’d keep the boards in the car for better days.

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.
