The Lowdown
Alright, Rusty here, lookin' at what's on the table.
Well, I'm not gonna lie to you, it’s been a quiet stretch around here, and frankly, it's gonna stay quiet for a good long while. We're lookin' at Hennemans, and the first real pulse of swell that even gets a whisper of a recommendation doesn't show up until the 20th of September. That’s a solid ten days or so with nothing worth paddling out for. A lot of those days are marked as poor, or just marginal at best with messy wind and onshore slop. You’re gonna be lookin’ at a long, dry spell on the beach.
Now, for Hennemans itself—it’s a reef setup that is notoriously inconsistent. It’s an exposed spot that wants swell from the west to really light up. The water temp is about average for this time of year, nothing crazy to report there. The energy we are seeing is all over the place, and most of it is junk.
The only light at the end of the tunnel, and I mean the *only* light, arrives on Sunday the 20th of September. That morning, we’ve got a clean-looking window. Light breezes from the SSW making it onshore, which isn't ideal, but the combined energy is jumpin' up to 900—that’s solid, moderate wave energy for sure. We’re talkin’ a 3ft swell from the SW, with a long period of 19 seconds. This is proper groundswell, the kind that wraps in with a lot of push and some nice shape, though on a beachier reef it can be a bit straight. Paddling out will be easier between the longer lulls. The afternoon hangs in there too, with 3ft from the SW (17s) and combined energy of 624, with those same light onshore breezes. It's still only a marginal call, the scores are low, but compared to the ghost town before it, this is the one. Monday the 21st and Tuesday the 22nd also keep some marginal hope alive with light cross-onshore breezes and clean-ish 3ft SW swells in the morning, but the 20th is the standout. It’s not a world-class day, but if you are desperate for a wave, that’s your window. Just know that crowds here can happen sometimes, so don’t expect to have the place to yourself.
Forget the rest of that second week, it’s more of the same—small, onshore, poor. Keep an eye on the charts, but for now, mark your calendar for the 20th of September and hope it holds.
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.
