The Lowdown

Alright, let’s talk about Blokken. I’ve got to be straight with you – this is a tough 16-day stretch. There’s nothing on the table that I’d call a good surf session. The whole forecast is a run of poor surf conditions, so don’t expect any standouts from me. It’s just one of those periods where the region goes quiet.

We kick off on Saturday the 12th of September with tiny, weak swell. Only 1.3 ft from the NW with a short 6-second period, all under a moderate cross-shore. Combined wave energy is just 11 – that’s weak. It’s the same story through Sunday and Monday: the swell stays under 3.3 ft, wind is either cross, cross-on, or onshore, and every time slot scores a zero for surf quality. There’s a brief moment on Monday the 14th morning where it’s clean with light cross-off wind, but the swell is a paltry 1.0 ft. Not worth paddling out.

Midweek, from Tuesday the 15th through to Thursday the 17th, the wind gets stronger – fresh to strong breezes – and the sea state turns lumpy and messy. The swell does push up to 4.9 ft on Thursday afternoon, with combined energy hitting 146, but that’s a moderate energy peak under strong cross-shore wind and a 6-second period. That’s a choppy, blown-out mess – feels more like a kite session than a surf session. The swell direction (WSW) is not the optimum NNW, so the break isn’t picking it up well either.

The following week doesn’t get any better. Friday the 18th to Monday the 21st is more of the same: strong onshore wind, lumpy conditions, and small swell. On Saturday the 19th morning, we see 5.2 ft from the W with a 6-second period and moderate energy of 177, but it’s under a fresh cross-off wind that leaves it clean. Clean, yes, but it’s short-period, onshore-direction swell (WSW vs optimum NNW), and still scores a zero for surf quality. It ain’t gonna shape up.

We limp through the rest of the period. The swell stays under 3.3 ft, period rarely goes over 6 seconds, and wind is either cross-on or onshore. There is one real tease: on Wednesday the 23rd, we get glassy conditions on the morning with 2.6 ft from the NNW and a 6-second period – combined energy 44 – but the surf is still rated as poor. That shows how flat it really is. After that, it’s back to tiny dribble under offshore wind on the 24th, and then more cross-shore chop through to the 27th.

No standout, no solid recommendation. The water temp looks about average for this time of year, so at least you won't be freezing, but that’s about it. Best to leave the boards at home and keep an eye on the charts. Forecasts can change.

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.
