Table - best surf conditions forecast for Fortress over the next 16 days.
Alright, Rusty here to give you the straight talk on Fortress.
The water is running real cold for the season – 65°, which is about 5° below average. You're gonna feel that.
Honestly, from July 10th through July 20th, there’s nothing doing. Tiny, weak surf – most days the swell is under 3 feet, with messy winds. The combined energy readings are in the teens and thirties – that's feeble. Even the few times the wind goes clean, there’s just no muscle behind the waves.
The first hint of life comes July 21st, Tuesday morning. A 6 foot swell from the ENE rolls in, energy jumps to 371, but it's cross-shore. Still only marginal.
The real score is Wednesday, July 22nd. That morning, Fortress gets a clean 6 foot swell from the SSE. The energy is a solid 554, and the wind is blowing cross-off from the SW. This is your best bet. The reef will hold that direction well, and the waves should have some proper shape. Newer surfers watch out – it's getting big.
That afternoon it jumps to 8 feet from the SSE, but the wind gets stiff and messy. Not the one.
July 23rd, Thursday morning holds strong at 8 feet from the S with a moderate breeze. Energy is still cranking at 841. This is expert territory – powerful, big, and consistent. Crowds will be a factor here as the spot is "often" packed.
The rest shapes up like this: July 24th and 25th see the swell slowly backing off. Saturday July 25th morning brings a smaller 5 foot swell from the S, light offshore wind, but the energy has dropped to 192. It's okay, nothing special.
So, the first two and a half weeks are a bust. But July 22nd and 23rd deliver the goods. Aim for Wednesday morning for the cleanest, most powerful session.
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.
