The Lowdown
G’day, I’m Rusty. Let’s call it like it is. The next couple weeks at Hennemans are mostly flat – a real struggle. The first hint of anything worth paddling out for doesn’t show up until Saturday, September 19th, and even then it’s just marginal. There’s a big dry spell before that, so don’t rush.
From the 19th, some small SW swell finally turns up. The water temp is 73°, which is about 5° warmer than normal – that’s properly warm for this time of year, no doubt.
Hennemans is a reef break that doesn’t fire often, exposed to the west. The best chance is Saturday morning the 19th, with little waves around 3 ft from the SW, with a long period of 18 seconds – that’s real groundswell. Wind is light cross-onshore from the W at 10 km/h, so it’s a little bit textured but still clean. The combined energy is moderate at 516. Not big, but for a quiet spot like this, it’s your best bet.
Sunday the 20th stays similar – 3–3 ft of SW swell, still a long 18-second period. Morning has a light onshore breeze, so it’ll be bumpy but surfable. Not a standout, just the best of a slow period. Crowds are sometimes around, so you might have it to yourself.
Monday the 21st sees 3 ft of SW swell with energy hitting 603 in the morning, but the wind is onshore from the SW at 15 km/h, so it’s going to be a bit messy. Still, that 17-second period gives it some grunt. After that, the swell fades. By Tuesday the 29th, we’re back to 2 ft with cross-onshore wind – nothing to get excited about. The last days of the month drop to 2–2 ft, with weak energy. Honestly, it’s grim – don’t hold your breath, but forecasts can change.
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.
