The Lowdown
Alright, let’s break it down for The Fort. Rusty here, and the outlook for the next 16 days is a tough sell.
The honest truth is there’s nothing worthwhile on the cards for a long stretch. The first several days are a total write-off. The scores tell the story: all zeros and ones. The main culprit is the wind. It's mostly a cross-onshore or onshore flow from the SSE, SSW, and WNW, just chopping up any swell that tries to show up.
Even when the swell energy picks up into a moderate range—like numbers hitting 206 and 224—the wind is just too messy to produce any clean surf. The swell direction (WNW or SW) is sometimes okay for The Fort's optimum SW angle, but the periods are either too short (8 seconds) or too long (14-19 seconds). That long-period SW groundswell from the 7th into the 8th is best for point breaks, not a spot like this, and with the onshore breeze, it'll just be lumpy.
The water temp is about 54°F, which is about 3°F colder than normal for this time of year, so you'll feel it.
From Tuesday, August 4th through Friday, August 8th, it's poor across the board. A bit of energy on Saturday the 9th (1.1m to 1.3m) and Sunday the 10th, but the cross-shore wind keeps it choppy.
There's a slight shift from Thursday, August 14th through Monday, August 18th, when we finally see some 'marginal' calls. The wave energy climbs into the high 500s and 600s (moderate to strong) on the 15th and 16th, and the wind gets light at times. This is your window, but it's a small one. By Saturday the 15th and Sunday the 16th, there should be a 0.9m SW swell at a 16-17 second period. With that light onshore wind, you might find a few fun, small waves if you’re patient. It's the best the forecast has to offer.
After that, Tuesday the 19th of August brings another short period WNW swell with cross-onshore winds, sending it right back to messy.
If you’re really jonesing, the weekend of the 15th-16th is your best bet. For the rest of the period, with the decent swell size and the constant cross-shore wind, it’s looking like a better setup for kite surfing than paddle surfing. Keep checking back, because the forecasts can change—this is a rough spell, but it won't last forever.
Rusty.

Information about the The Fort Surf forecast
The above surf forecast table for The Fort provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at The Fort can be found by selecting the local surf guide option on the grey menu. Our The Fort 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.

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 The Fort 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.
