Table - best surf conditions forecast for Fortress over the next 16 days.


Hey folks, Rusty here. Well, I've scoured the charts for the next couple of weeks, and to be honest, it's looking pretty bleak for a proper surf at Fortress. We've got a long stretch of mediocre conditions ahead, so let's break it down.

The overall pattern is one of small, weak swells getting chopped up by all kinds of wind. The water temp is sitting at 69°F which is pretty average for this time of year, nothing to write home about. The only real standout, and I'm using that term loosely, is a small window right at the end.

Starting off, Tuesday the 7th is a write-off. We've got a northeasterly howling at 28 mph with light rain, making a total mess of the 4ft NE swell at Fortress. The combined wave energy is only moderate at 155, but the cross-shore wind just kills it. Zero to recommend.

Things don't get much better. Wednesday the 8th morning offers a moment of calm with glassy conditions and a clean 3ft E swell, but the period is a short 8 seconds and the wave energy is weak at 130. It's surfable, but very ordinary. The rest of that week and into the next is a parade of tiny swells – we're talking 1ft to 3ft – with cross-offshore and onshore winds that never quite line up right.

There's a real gap in quality from Wednesday afternoon right through to Saturday the 19th. All those days are filled with small, weak swell and winds that are either cross, cross-on, or just too strong. The combined energy during this stretch is mostly under 100, which tells you how little power is in the water.

Now, Sunday the 19th morning is our one and only true standout. The wind drops to nothing – glassy – and we get a 3ft SSE swell wrapping in. The period bumps up to a solid 8 seconds, and the combined energy jumps to a moderate 141. This is the best we'll see. For one morning, Fortress will have clean, surfable waves. It's a reef break, so with that longer period, it might hold up nicely for a beginner-friendly wave. Expect crowds to be likely here, because everyone will be trying to get in on the only decent session.

Monday the 20th morning picks up a touch with a 4ft SSE swell and a 9-second period, pushing the wave energy to a moderate 199. It's got more size, but the morning is cross-shore with a light breeze, so it'll be a bit rippled. Not as clean as Sunday. After that, the last few days fade back into small, clean but weak cross-offshore conditions.

So, to wrap it up: don't get your hopes up for the next week and a half. Surf the glassy Sunday the 19th morning – that's the one to point your car at. After that, keep an eye on Monday morning the 20th as a backup. It's a long wait for not much, but that's how it goes sometimes.

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.
