The Lowdown
Righto, Rusty here. Let's have a proper look at what's on offer for this stretch, focusing on Hennemans, a reef break that needs a clean W swell and offshore winds to really fire. To be honest, mate, looking at the whole 16-day window, it's a grim run. There's nothing that jumps out as a proper standout session.
The period starts on Thursday, 13th of August with a bit of swell from the southwest, around 2ft. The problem is the wind is howling from the WSW at 6 mph, putting it onshore and ruining any chance of a clean wave. The combined energy is a modest 328, and the swell is a long-period 16-second groundswell, which would be good for a reef, but not with that wind. It's a write-off. Thursday afternoon and all of Friday look even worse; the swell gets a tiny bit of energy (up to 509) but the wind stays in an ugly cross-onshore position.
There's a glimmer on Saturday morning, 15th of August. The swell pushes up to 3ft from the SW, still with that long 16-second period, and the wind swings to a straight cross-shore from the WNW at 9 mph. It’s not perfect, but that cross-shore breeze at least takes the worst of the chop off. The combined energy is a moderate 548. It's marginal, not a classic, but it's the best the whole fortnight has to offer. The afternoon sees the swell hit 4ft with 603 energy, but the wind turns cross-onshore again, making it choppy.
After Saturday, it's a slow bleed. The wind stays predominantly cross-onshore or onshore right through until the 28th of August. The swell drops back to the 2ft to 3ft range, and the period fluctuates between a weak 13 seconds and a longer 19 seconds. Every single session is flagged as either "poor surf conditions" or "marginal surf forecast". There's no clean window with a decent offshore breeze.
Given there's zero consistent quality on offer, and this break is already known to be inconsistent, a blank run like this is pretty normal for the area. You'd be wasting your time and petrol chasing anything here over the next two weeks. The water temp is about average for this time of year, so at least you won't be freezing while you're sitting there watching the chop.
Stay patient, brother. Looks like a good time to wax the longboard for a flat day cruise or check the kite gear if you're into that.
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.
