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


Alright, let’s break it down for the next couple of weeks. Honestly, it’s a grim stretch for Fortress. This is a reef break that’s exposed to the swell, and it usually wants something from the SE, but the ocean just isn’t cooperating. For the first twelve days, we’re looking at a whole lot of nothing – tiny, weak, or just plain messy conditions. The water temp is sitting around 68°, which is basically average for this time of year, so no surprises there.

The only real glimmer of hope, and I mean the *only* one, shows up much later. On Monday, July 20th, in the morning, a solid 7ft S swell rolls in with a period of 8 seconds. The real kicker is the wind – glassy. Dead flat, no wind. That’s about as clean as it gets. Combined wave energy is up at 987, which is serious. Now, that size is over 5ft, so it’s not a beginner wave, but for experienced surfers, that morning window is your standout of the whole 16-day run. The cross-shore wind in the afternoon will chop it up pretty quick, so it’s a small window.

Before that? A long dry spell. From the start all the way through to the 19th, nearly everything is a poor surf condition. The waves are tiny, the wind is all wrong, and the energy is barely there. A few mornings show clean conditions but with next to no swell – not worth paddling out for.

After the 20th, it drops back down to 5ft or less, with onshore winds returning, so that Monday morning is the one to circle on the calendar.

Stay patient, a big swell with glassy conditions doesn’t come around often here, but when it does, you get on it.

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.
