The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the menu for the next two weeks at Hennemans. It’s a reef setup, but I gotta be straight with you—this ain’t a classic run. The swell is coming from the west-southwest, which is good for this spot, but everything else is a bit of a struggle.
We kick off on Wednesday, 9th September, with a clean morning. The swell is a tiny 2ft from the SW, but with a very long period of 16 seconds, so there’s some real groundswell energy in the water (combined energy of 365). The wind is light and offshore from the SW, which is a major positive—that reef will be glassy. The water is sitting at 72°, which is a touch warmer than normal for this time of year. The catch? It’s only an inconsistent wave, and the forecast calls it marginal. For a surfer, that means small, clean, and waiting for the right set. Thursday morning (10th) sees a tiny bump to 3ft from the SW, but the wind swings cross-onshore from the SSW, so it’ll be a bit choppy. Not the best.
Friday through to Monday (11th to 14th) is a real write-off. The wind is onshore or cross-onshore, the swell is a mixed bag of short-period windswell and some leftover groundswell, but the conditions are poor. Saturday morning (12th) has a light onshore breeze and a weak 3ft SW swell (combined energy 338), but it’s just not happening. Even the afternoon on Sunday (13th) has a 4ft west swell, but with a short period of 8 seconds, it’s messy and unappealing.
Tuesday morning (15th) we get a bit of a reprieve—clean offshore wind again, but the swell drops right back to 2ft from the SW with a very long period of 16 seconds. It’s small and inconsistent, but the glassy conditions make it a board-in-the-water option for the patient surfer. The combined energy is only 225, so it’s weak.
The real standout—and I mean the only one worth circling on the calendar—is the afternoon of Saturday, 19th September. The wind goes light and cross-shore from the WNW, which is about as good as it gets for this spot. The swell is 3ft from the SW with a solid 18-second period, and the combined energy jumps to 569. That’s a moderate energy, but with that period, the reef should start to throw some proper lines. It’s still marked as marginal, but the cross-shore wind and long period suggest it could be a fun, clean session if you’re not expecting bombs. The crowd is listed as "sometimes," so you might have a few locals out, but it won’t be a circus.
Sunday afternoon (20th September) is a close second—same swell size (3ft, SW, 18 seconds), combined energy of 608, and a gentle cross-shore wind from the WNW. It’s very similar to Saturday afternoon, but the wind is a touch stronger, so Saturday gets the edge.
Beyond that, the second week (21st to 24th) is all small, marginal, or poor. The swell holds around 3ft to 3ft from the SW, but the wind is mostly cross-onshore, and the periods drop off. The combined energy stays moderate (300-600 range), but the conditions are just not clean enough to get excited about.
Overall, this is a tricky 16-day window for Hennemans. The spot is inconsistent and only gets a handful of sessions that are worth the paddle. The cleanest, most promising window is the afternoon of Saturday, 19th September, and maybe Sunday the 20th. For the rest, it’s a waiting game. Stay patient.
Rusty.

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