The Lowdown

Alright, let's talk Hennemans. The outlook for the next couple of weeks is a bit of a flat spell, to be honest. The first ten days or so are really not offering anything worth paddling out for. We’ve got a long stretch of marginal and poor conditions from Monday the 17th right through to late August. The swell is tiny, mostly around 1 ft to 3 ft, with a lot of onshore and cross-onshore wind messing things up. That first Monday morning on the 17th has the best shot of the early period, with a clean 3 ft SW groundswell (14 seconds) and cross-shore breeze, but even that’s only rated as a marginal call. The water is a balmy 72° which is much warmer than normal for this time of year – pretty nice for a dip but not for surfing.

From the 29th of August, things start to look a little more promising, but still not clean. On Saturday the 29th, we see the swell finally bump up to 3 ft from the SW, with a solid 17-second period on the morning. The combined wave energy hits 609 (moderate energy), so there’s some push in the water. The problem is the wind is onshore, keeping things messy. That trend continues into Sunday the 30th, with a 3 ft SW swell and energy at 659, but again, onshore breeze means it’s not the clean, glassy day we’d want.

The best of the whole forecast, and I mean the only real standout, is the morning of Monday the 31st of August. The swell is 4 ft from the SW, with a 15-second period, and the combined energy is a solid 578. It’s still a marginal call because of the rain showers and onshore wind, but if you have to get wet, that’s your window. The break is an exposed reef, and it’s inconsistent, so you’ll be waiting for sets, but when they come, there’ll be some push. Crowds are possible here on a good day, so you might have some company.

For the rest of the run into early September, it’s more of the same: small, choppy, and onshore. Not the time to be planning a surf trip.

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.
