The Lowdown
Alright, let's cut to the chase. The next couple weeks at Hennemans are going to test your patience. This reef break is inconsistent, and the forecast is mostly a bummer. Water temps are about normal for this time of year, so no surprises there.
From Friday the 11th through Thursday the 17th, it's basically a write-off. Swell is small, 2 to 4 feet, from the southwest. Winds are mostly cross-onshore, making things choppy. The energy is weak to moderate, so you'll be scratching for anything. Not worth the effort.
Things get slightly more interesting Thursday afternoon the 17th. The wind turns more cross-shore, and the energy picks up a bit. Friday the 18th brings a proper groundswell with a 19-second period. It's still small, around 2 feet, but that long period could make the reef work a little better. The energy is moderate too. The weekend of the 19th and 20th sees the swell nudge up to around 3 to 3 feet, still from the SW, with a period of 18 seconds. Energy keeps building, especially Sunday morning. But, the wind is mostly onshore or cross-onshore, so it won't be perfect. These are your best days, but they're still marginal at best.
The final stretch from Monday the 21st through Saturday the 26th is another letdown. Swell drops back down to 2 to 3 feet, energy fades, and the winds stay cross-shore. The long period swells are gone. It's just a lot of nothing.
So, your best bet is that window from Friday the 18th through Sunday the 20th. The swell direction is good for the spot, and those longer periods might just offer a bit more shape. It won't be big, and it won't be clean, but it's the most hope you'll get. Otherwise, maybe find something else to do.

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.
