The Lowdown

Alright, let’s get into it. The next couple of weeks are looking pretty bleak for surfing here at Fortress. We’ve got a long stretch of small, weak, and messy surf ahead, so you might want to dust off the longboard or find something else to do for a while.

The pattern starts with a few days of just about nothing. Through Wednesday and Thursday, we’re looking at tiny 2ft windswell with short, crumbly 6-7 second periods. The wind is all over the place, mostly cross-shore, and the energy is just pathetic. It’s not even worth paddling out for that.

Friday brings a slight bump, with the swell pushing up to 4ft on Friday morning. The period is still a short 6 seconds, but the wind goes light and cross-offshore, which will clean it up a bit. It’s surfable, but honestly, it’s pretty ordinary. The energy is still weak to moderate, but the shape will be junky. If you’re desperate, that’s your window, but don’t expect much.

The weekend is a write-off. Saturday and Sunday are all small, with the swell dropping back down to around 2-3ft and the wind staying cross or cross-off. The energy is weak, and the surf is just poor. There’s no power, no push, and it’s just lumpy.

Next week doesn’t get any better. From Monday the 11th through the 17th, we’re stuck in a rut of tiny, weak surf. The swell hovers around 2ft to 3ft, with occasional bumps to 4-4ft, but the period stays short and the wind is consistently onshore or cross-shore. There’s a chance of some cleaner conditions on the 14th morning with a light offshore, but the swell is just too small to get excited about.

The one bright spot in this whole sorry forecast is the morning of Tuesday the 18th of August. We finally get a little bit of a pulse. The swell fills in to 4ft, with a slightly longer 8 second period, and it’s glassy. The wind is dead, just a slight air, and the energy is moderate. It’s the best the break will look in the whole 16 days. It’s still not a classic day, but it’s the only one worth planning for.

After that, it fades back into the same old story: small, weak, and messy. The water temp is about average for this time of year, so no surprises there.

So, yeah. It’s a pretty flat, frustrating run. The 18th morning is your window. Don’t hold your breath for anything else.

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.
