The Lowdown
Alright, Rusty here. Let me break down this stretch we’ve got coming up for Blokken.
First off, I gotta be straight with you – this next sixteen days is a bit of a write-off for decent surf. The forecast shows a lot of wind issues, small swell, and just messy conditions. There’s not a single standout session in this whole run. The first recommendation doesn’t come in until Thursday the 20th of August, and even then, it’s a no-go.
We’re looking at a long gap of poor conditions. From the get-go on Thursday afternoon, the 20th, it’s a risk of thunderstorms with a strong 22 mph WSW wind making for lumpy, cross-shore chop on a tiny 4 ft swell. Not worth paddling out. That trend continues through the weekend and into the next week. Friday the 21st, Saturday the 22nd, Sunday the 23rd – all small, choppy, and onshore.
We get a bit of a clean-up from Monday the 24th onwards, with some offshore breezes and clean-looking water, but the swell drops right off to a pathetic 2 ft. The only positive is the water temp is much warmer than normal, about 3° warmer than average for this time, which is pretty unusual. But that doesn’t help the waves.
The swell tries to pick up again on Wednesday the 27th of August heading into the 28th, with a 4 ft to 5 ft swell, but it’s getting hammered by a strong 28 mph SSW wind. That’s brutal. By the 29th and 30th, it’s back to tiny, weak surf with poor wind. Even the glassy conditions on Wednesday the 26th afternoon are on a 1.0 ft swell with next to no energy.
Honestly, for Blokken, this is a blank run. The exposed nature of this break means it’s always at the mercy of the wind, and with the swell being so small and inconsistent, there’s just no window for a decent wave. Don’t bother waxing up for a while.
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.
