The Lowdown

Alright, Rusty here. Let's have a look at what's cookin' at Hennemans over the next couple of weeks.

Honestly, it's a bit of a quiet stretch. There's not a whole lot to get genuinely frothy about. The main energy comes from a long-period SW groundswell, peaking around the 4ft mark with those long 16-second intervals, which gives it some punch for a reef setup like Hennemans. The combined wave energy will get up into the moderate range, hitting the mid-600s to 700s over the first weekend (648 to 735). Water temp is a wild one – we're sitting at 75°, which is a whopping 7° warmer than normal for this time of year. That's really unusual, so don't expect that winter chill.

Starting out on the 28th of August, we've got a tiny 2ft swell with that long 16-second period. The wind is cross-onshore from the WSW, which is a bit of a buzzkill for a reef like this. It looks small and a little bumpy. Not worth paddling out for.

Into Saturday the 29th, the swell bumps up to about 4ft from the SW, still with that long 16-second period. The wind swings a bit, but stays cross or cross-onshore. It'll be slightly messy with that gentle breeze. The energy is moderate, but the conditions aren't clean enough to call it a standout.

Sunday the 30th is pretty similar – 3ft SW swell, but the period drops slightly to 14-15 seconds, and the wind remains a problem, mostly cross-onshore. It’s just not coming together.

The first week of September looks frustrating. We've got a pulse of slightly better energy around the 3rd and 4th, with a 3ft to 3ft SW swell and periods reaching up to 18 seconds on the 3rd afternoon. The combined energy pushes up (529 to 866), but the wind is either cross-on or cross, and the comments keep saying "marginal" or "poor". It's just too choppy and messy to get excited about. That 18-second period is very long, and at a beachy reef like this, it might just roll through too straight.

The best-looking window, and I mean the *only* decent option we’ve got, falls on Wednesday the 9th and Thursday the 10th of September. On Wednesday the 9th, we see a 4ft SSW swell with an 11 to 12-second period. The wind on Wednesday morning is light and cross-shore from the NW. That is your window. The combined energy is in the moderate range (517). Thursday the 10th is similar – 4ft SSW swell, 12-15 second period, and a gentle cross-shore breeze. It's not epic, but it's the cleanest and most rideable the forecast gets. The risk here is that with the swell just over 3ft and a fairly long period, it might be a bit walled-off for a beach break, but for a reef, it should offer some nice, lined-up walls.

After that, into the second week, it fades back down to small, weak, and messy. From the 11th onwards, we're looking at 2ft to 3ft swells with poor wind and low energy (in the 280s to 500s). Not worth the drive.

So, to be straight with you: there’s no standout, world-class session on the cards. But if you're desperate for a paddle, set your alarm for the morning of Wednesday the 9th or Thursday the 10th of September. Light winds, a bit of size, and the best chance at a few clean corners at Hennemans.

That’s it from me. Keep your eyes on the horizon.

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.
