The Lowdown
G’day, Rusty here. Look, I’ve gotta be straight with you – the next couple of weeks at Blokken are looking pretty grim for a proper paddle session. We’ve got a long, flat stretch ahead before anything really gets going.
Right now, the water is sitting at a balmy 70°, which is a solid 5° warmer than usual for this time of year. That’s definitely notable, a real muggy feel in the air.
From Tuesday the 25th of August right through to the end of the month, it’s mostly tiny, weak dribble. The swell heights are barely a bump, mostly under 2 ft, with periods around 5-6 seconds – that’s just wind slop. The winds are coming in cross-off or cross, but the energy just isn’t there. The combined energy is mostly in the single or low double digits (14, 11, 2), which is very weak. Not worth paddling out for.
Friday the 29th sees a bit of a pulse, with swell jumping to 5 ft from the W and WSW, period hitting 6 seconds. The combined energy climbs to 187-194 – that’s moderate – but the wind swings to a strong cross and cross-shore, over 22 mph, making for lumpy, messy conditions. Not great.
Through the first week of September, we get a mixed bag. Monday the 31st of August and Tuesday the 1st of September see a rise to 7 ft and 6 ft, but with near-gale winds and strong breezes, it’s blown out and messy. The energy is strong (456 on the 31st) but it’s a total write-off for a clean paddle.
By Wednesday the 2nd of September, the swell hits a peak of 10 ft from the WNW with an 8-second period. The combined energy is a massive 1431 – very strong. But the file says it’s predicted to be too big for this break, and the wind is a fresh cross-shore. This is expert-only territory, if anyone even tries. Again, not the clean, lined-up waves we want.
The best chance you’ll see is Wednesday the 9th of September. The swell is a solid 5 ft from the NW with a 7-second period, giving combined energy of 221-233. Crucially, the wind is a light to gentle cross-off breeze from the East, at 6-9 mph. That means clean conditions. There’s a chance of a few workable waves, but the rating is low and it’s still a gamble this far out. It’s the only day in the whole two weeks that even hints at fun surf, so keep an eye on it. Crowds are possible later.
Other than that one morning, it’s a barren run. The rest of the time is flat, too big with bad wind, or blown out. Honestly, if you’re desperate, the setup is more interesting for kite surfing on those big, windy afternoons than for a paddle session.
Rusty.

Information about the Blokken Surf forecast
The above surf forecast table for Blokken provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Blokken can be found by selecting the local surf guide option on the grey menu. Our Blokken 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 (Blokken) 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 Blokken 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.
