The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming down the line for the next couple of weeks.

Gonna be a tough stretch, I won’t sugarcoat it. We’ve got a persistent run of cross-onshore and cross-shore winds that are gonna mess up the surface on most days. The swell is around, but it’s just not lining up clean. You’ll be looking at a lot of choppy, wind-affected conditions, and the forecast is pretty locked in on that for a while.

The first real chance to get wet that’s even worth a mention is Thursday, September 17th, in the morning at Hennemans. Even then, it’s a marginal call. You’ve got a 3 ft SW swell with a very long 15-second period pushing in, and the combined energy is moderate at 425. The wind is light cross-onshore, so it’ll be a bit bumpy, but for a die-hard, it might just be rideable.

It’s a reef break, so that long-period groundswell will wrap in and shape up better than it would at a beachie. Water temps are about average for this time of year. Just be aware, it’s an inconsistent spot that rarely fires, and when it does, you might have company – crowds are possible here.

We roll through the rest of September and the vibe doesn’t really lift. The theme is light to moderate onshore breezes from the west and northwest, with swell hanging around the 2 ft to 3 ft mark. The energy stays mostly in the moderate range (between 277 and 613), but the wind keeps it messy. You’ll see a few mornings rated “marginal” – like Sunday the 20th afternoon and Monday the 21st – but the wind is never truly clean.

The single standout, if I have to pick one, is the morning of Saturday, September 19th. The swell is 3 ft from the SW with a nice 18-second period. The combined energy hits a moderate-high 510, and with just a 6 mph cross-on breeze, it’s the closest we get to decent shape. Still not perfect, but for this stretch, it’s the best on offer. The reef will handle that long period well, keeping it from walling out.

After that, the pattern holds through the end of September and into the first of October. Winds get a bit stronger, shifting more cross-shore, and the swell size drops. By Thursday, October 1st, we’re down to a tiny 1 ft SW groundswell with a 18-second period and a combined energy of only 220. That’s weak sauce, barely a ripple.

Overall, there’s a 2-week gap of poor to marginal conditions with no true clean surf. Keep your expectations low, and if you do paddle out, you’ll be working for every wave. Forecasts can change, but right now, it looks like a period to tune the boards and wait.

Stay frothy,
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.
