The Lowdown
Alright folks, Rusty here. Let's look at the next couple of weeks for Blokken. Straight up, I gotta be honest with you – it’s a pretty grim outlook. The forecast is basically a big, long stretch of poor surf conditions with next to no quality on offer. There are no true standouts here; nothing I can confidently tell you to pack your board for.
We kick things off with nothing happening. The first few days are a total write-off. Sunday the 13th starts with a tiny, weak 2ft swell from the NW with a short 5-second period, and it's onshore wind. The water's warm though, a notable 67°F which is a couple of degrees above the norm for this time of year. Even so, the surf is flat and junky. We then go through a week of nothing but zero-rated conditions. The swell energy is very weak for days, mostly under 100, like 17 (combined swell energy) on the 14th, and barely nudging 35 on the 15th. Winds are mostly cross or onshore, creating chop and no shape.
The only uptick in energy comes around Wednesday the 16th, with a 5ft WNW swell, but it’s blown out by onshore winds. The energy climbs to a moderate 127, but the wind keeps it unsurfable. The same story repeats through the rest of the week. By Saturday the 19th, we see the biggest swell of the period – a 7ft WSW swell with a combined energy of 348 – but it's accompanied by a strong breeze making a total mess of things. That's more of a kite surfing kind of day than a paddle surfing kind of day.
Into the second week, the last week of September, the pattern doesn't improve. You'll see some days with a bit more size, like Tuesday the 22nd with a 5ft NW groundswell hitting 240 energy, but again, the wind is cross-onshore or onshore. It just stays consistently poor for surf quality across the entire 16-day window. The crowds at Blokken are listed as "sometimes" an issue, but honestly, with conditions like this, I doubt you'll have to worry about company. The swell direction never matches the optimum NNW direction with clean offshore winds.
It’s a tough run. For a spot that can be inconsistent, this is a proper blank spell. Sometimes that's just how it goes around here. We can only hope the models shake up a bit soon.
Stay hopeful,
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.
