The Lowdown

G’day, I’m Rusty. I’ll be honest – this 16-day stretch for Blokken is a rough one. We’ve got a long, flat-to-poor run with hardly anything worth suiting up for. The first decent chance doesn’t roll in until Sunday the 23rd of August, and even then it’s barely a ripple.

From now right through to Saturday the 22nd, it’s dead. The swell is tiny, mostly under 2 ft, and onshore winds are all over the shop – NNW and NW mostly, blowing 12 to 25 mph, making it choppy, lumpy, and cross-onshore. There’s a slight bump mid-week around Wednesday the 19th with the swell pushing 4 ft from the WNW, but the wind is blowing 19 mph cross-onshore from the W, and the combined energy is still weak at 72. It’s messy, and the wave comment calls it poor. Don’t bother.

Now, Sunday the 23rd of August morning – that’s our one tiny glimmer. Blokken picks up a 2 ft swell from the N, period 7 seconds. The wind goes glassy from the NW, just 3 mph, and conditions are glassy and clean. The energy is only 51, so it’s small and weak, but the glass means it’s at least smooth and rideable for a beginner on a foamie. The water temp is 72°, which is a whopping 7° warmer than normal – very unusual and pleasant if you’re in a spring suit. But don’t expect much; the wave comment says “surfable waves but very ordinary conditions.” It’s inconsistent here too, so you’ll be waiting for sets.

Monday the 24th morning has another glassy start with 2 ft from the N, but period drops to 4 seconds and energy to 39 – that’s short-period, weak, and pretty gutless. Afternoons turn cross-onshore and choppy again.

The only other half-decent moment is Saturday the 29th of August morning. We get 4 ft from the W, period 5 seconds, with a gentle 9 mph cross-offshore breeze from the E. The wave comment says “surfable waves but very ordinary conditions” – energy is 85, still low. It’s clean, but the swell is short-period and won’t offer much push. For an expert, it’s a waste; for a learner, it’s maybe worth a splash if you’re desperate.

Overall, there is no standout day. The best on offer is Sunday the 23rd morning for absolute beginners wanting a glassy, tiny wave, or Saturday the 29th morning for a slightly bigger but still ordinary clean bump. Nothing here for anyone serious. Crowds are “sometimes” at Blokken, but honestly on these days, you’ll pretty much have it to yourself.

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.
