The Lowdown

Alright, let’s size it up in feet and miles per hour.

It’s a lean run ahead for Fortress. We’re lookin’ at a long stretch of mostly tiny, weak surf with ordinary to poor conditions, so it’s gonna take some patience.

The week kicks off Wednesday the 5th with ankle-bitin’ 2ft SSE swell and a short 7-second period, bumpy with a cross-shore breeze. Not worth wettin’ a wetsuit. Thursday the 6th stays small—3ft to 4ft—and though the wind turns cross-offshore in the morning, the swell’s gutless and short, so it’s just a tease. Friday the 7th morning shows a little flash: 3ft SSW groundswell, cross-off breeze, clean… but it’s a 1/10 call. Barely surfable. Afternoon gets messy with cross-wind and chop.

Saturday the 8th is more of the same—small, short-period stuff with gusty winds. Sunday the 9th morning is the one faint highlight: 4ft SSW swell, 6-second period, light west breeze, clean. The combined energy hits 208 (moderate), and the score nudges to a 2/10. That’s as good as it gets in this window. Even then, it’s short-period and a reef break, so it won’t be any kind of standout. Water temp’s around 70°, about average for the time of year.

From Sunday afternoon onward, it’s a sad tale. Monday the 10th drops back to 2ft, Tuesday the 11th has offshore wind but barely 3ft, and Wednesday the 12th goes glassy but tiny at 2ft. The rest of the second week—right through to Wednesday the 20th—hovers between 0.5ft and 5ft, with period never climbing above 9 seconds. The 5ft spike on Thursday morning the 20th (SSW, 7 sec) carries 196 combined energy (moderate), but it’s cross-shore and messy again. No surf worth chasing.

Bottom line: there’s a gap from now right up to Sunday morning the 9th for the only slight possibility, then another long dry spell. For a reef that needs a bit of push, this is a tough outlook. Better luck next time.

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.
