The Lowdown
Alright folks, Rusty here. Let's have a look at the forecast for Hennemans. It’s a reef break that’s exposed to the west, and it’s known for being a bit of a tease – inconsistent at the best of times. The water’s sitting at 73.6°, which is a serious three degrees warmer than normal for this time of year. That’s a big deal; it’s like the ocean’s cranked the heating on.
Right now, we’re in a bit of a flat spell. The energy in the water is weak, and there’s just not much pushing in. The swell that does arrive is all over the place, small and often messy with the cross-onshore winds. Honestly, the first week of this window is a write-off for a proper surf. From Saturday the 15th through to Friday the 22nd, you’re looking at ankle to knee-high dribble, with winds that keep it choppy or rippled. It’s not worth suiting up for, unless you just want to get wet. There’s a glimmer of hope on Sunday morning the 24th though. The wind drops right out, going glassy, and the period jumps to 20 seconds. It’s small, only 2ft, but it’s clean and lined up. For a short while, it could be the best, most peaceful wave you’ve had in ages if you’re on a longboard.
Then things start to get interesting for the last week of August. We see a real pulse of energy arrive. The swell builds to 5-6ft, with a period of 13-16 seconds. It’s a proper groundswell, but it’s coming from the south and southwest, which is off-optimum for the west-facing setup at Hennemans. It’s going to be a bit crumbly and maybe not as clean as we’d like, but there’s finally some size and push to it. This is when it gets more interesting for the experienced crew. The winds stay light and mostly onshore, which will keep the surface a bit lumpy, but there’s enough juice in the water to make it feel proper.
All in all, the first half of the fortnight is a waiting game. But there’s some promise on the horizon around the 25th to the 27th as that bigger, longer-period swell fills in. It’s a long way out, so take it with a grain of salt, but it’s looking like the most promising push in the whole run.

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.
