The Lowdown
G’day, Rusty here. Look, I’ve been staring at the charts for Blokken and I’ve got to be straight with you: it’s a tough stretch. The entire 16-day window is a write-off for any proper surf. We’re looking at a whole lot of nothing, with the odd bit of junky windswell that’s not worth paddling out for. The first couple of days are a mess, with a stormy Wednesday whipping up 6.9ft of onshore slop, but that’s just lumpy, blown-out chaos. After that, it just fades away into a long, flat spell. There’s a decent-looking glassy morning on the 14th (Monday), but there’s barely a ripple – only 2ft of weak, short-period swell. Just not enough push.
The truth is, for the next two and a half weeks, the energy just isn’t there. The combined swell energy stays in the weak to low-moderate range, mostly under 60 (like the 56 on Friday the 11th), and the period stays stubbornly short, rarely getting over 7 seconds. That’s just not going to produce anything with any shape or power. We do get a few cleaner windows with light offshore or glassy conditions – like the morning of the 14th (Monday) and the 18th (Friday) – but there’s no swell to back it up. It’s the classic case of a clean ocean with no waves in it. The water temp is running about 68.5° on that first day, which is much warmer than normal for this time of year, but you won’t feel it while you’re just sitting there bobbing around.
Honestly, if you’re desperate, that Monday the 14th might be the least-bad option – clean and glassy, but the swell is only 2ft from the north with a tiny 5-second period. It’s a beginner’s wave at absolute best, and even then, you’ll be fighting for a dribble. The 18th (Friday) is similar, with a bit of a cross-off wind and 1.6ft of north swell, but it’s just as weak. Once the wind cranks up again from the west late in the month, it’s all over. There is no standout, no hidden gem, no session to get excited about. It’s a proper blank run, and for a spot like this, it’s just one of those spells where you hang up the board and do something else. Be patient, mate. It tends not to stay this poor for long.

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.
