The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s cookin’ for Fortress.
Honestly, the next week and a half is a bit of a grind. We’re lookin’ at a long stretch of weak, short-period windswell mixed with onshore or cross-onshore breezes. The water temp is runnin’ about average for this time of year, so no shock there. The first real glimmer of hope doesn’t show up until Saturday the 1st of August.
That Saturday morning is the one true standout in the whole 16-day window. We’ve got a clean 4ft swell out of the south, period of 8 seconds, and the wind is glassy. That’s a rare combo for Fortress, and it’ll be proper clean. The combined wave energy is moderate at 229, so there’s enough push to get a few fun ones. It’s a reef break, so expect some nice shape off that south swell. Crowds are often here, so you won’t be alone. The Saturday afternoon gets a bit dicey with a cross-offshore breeze pickin’ up, so get your session in early.
Before that, there’s a couple of days that are just barely on the radar. Wednesday morning the 30th of July, we’ve got a 5ft south swell with 9-second period and light cross-onshore wind. The energy is moderate at 323, but the conditions are still listed as poor. The next morning, Friday the 31st, the wind goes clean offshore out of the WNW, with a 3ft south swell. It’s surfable, but it’s little and ordinary. Still, if you’re desperate, that’s your window.
The rest of the period is a write-off. Tons of days with small swell, onshore wind, and choppy conditions. Nothing kite-worthy, either. Just a long, flat, frustrating stretch.
Best bet: Glassy Saturday morning, August 1st. That’s the one.
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.
