The Lowdown
Alright crew, Rusty here. Let’s be straight up – the next couple of weeks are a battle. The only spot showing anything is Hennemans, and it’s a real struggle for most of the outlook. The first half-decent chance isn’t until Wednesday, August 19th. The first couple of days are basically a write-off.
So, come Wednesday morning the 19th, Hennemans is showing a tiny 3ft of SW groundswell. The period is a nice 16 seconds, so it’s got some legs. The combined wave energy is moderate (384). Wind is a light cross-onshore, keeping the surface a bit bumpy. It’s a marginal call, just enough to get wet. Water temp is 71°, which is a touch warmer than usual for this time of year.
The whole first week is a broken record: small SW swell, mostly 2ft to 3ft, with a persistent light cross-onshore or onshore breeze. The break is inconsistent anyway, so you’ll be waiting. The best of this first week is probably Wednesday afternoon the 19th when the wind goes light onshore, or Saturday the 22nd in the afternoon with a 2ft, 15-second period swell.
The second week is just more of the same small stuff and messy winds. It’s a real dry spell. Then, finally, a glimmer way out. On Saturday, August 29th and Sunday, August 30th, the swell kicks up a notch. Saturday afternoon shows 3ft from the SW with a 16-second period, and the combined energy jumps into the strong range (578). The wind is still a light cross-onshore though. It’s the best looking waves in the whole 16-day stretch, but it’s a long way off, so don’t get your hopes up too high.
For the rest of it, the swell is weak and the wind is never glassy. If you’re into kiteboarding, that constant side-breeze over a beach break might be your jam. There are big gaps in the action here.
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.
