The Lowdown

Alright folks, Rusty here. Let’s get real about what’s shaping up at Blokken. I’m not gonna sugarcoat it – this 16-day outlook is a tough pill to swallow. We're looking at a long, quiet spell.

The pattern is ugly for the first week and a half. There is surf, but it's almost all junk – blown out, choppy, and messy. The wind has been hammering from the west and southwest, putting a nasty cross-shore or onshore chop on everything. We get a pulse of moderate energy around the 19th, with combined energy hitting 258 on Saturday morning, but that fresh cross-shore wind will make it lumpy and frustrating. For a spot that needs that clean south-easterly offshore breeze, this is about as bad as it gets.

Water temp is notably warm right now at 68°F (5°F above average), so at least you won't be cold while you're wondering where the waves went.

There is one tiny window. On Monday, September 21st, the wind finally drops and swings to a light cross-offshore from the south-southwest. We’ll see a knee-high 3ft swell from the NNW, with combined energy at a modest 108. It’s clean, but small and short-period (7 seconds). It’s "surfable but very ordinary" – that’s the bar we've got. That’s the only real recommendation in the first nine days.

After that, it’s a flat spell. From the 22nd through the 29th of September, it’s mostly tiny or flat, with wave heights barely scraping 1.0ft and combined energy dropping into single digits. The wind goes clean offshore or glassy on a couple of days (like the 24th), but there’s no swell to push. You’d be paddling for ripples.

The only other glimmer is way out on the 30th of September. The model hints at a big shot of swell from the WSW, with combined energy rocketing to 479. The problem? That 8ft swell is coming with a nasty onshore wind from the north-northeast. That’s expert-only, blown-out chaos, and far too unreliable to call a standout.

So, the only real standout – and I use that term loosely – is Monday, September 21st. If you are desperate for a paddle, hit it early morning when the wind is light and the wave is just about rideable. It’s the only clean, surfable moment in a sea of poor conditions.

This is a classic run of poor consistency for the area. We just have to wait for the next solid south-easterly to blow in. Forecasts can change, but for now, this is a rest-up period.

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.
