The Lowdown

Alright, Rusty here. Let's have a look at what's on offer for the coming weeks at Blokken.

Alright mate, I gotta be straight with you – the next week and a half is going to be a tough slog. We've got a long stretch of real poor conditions, with a few small windows where you might get wet, but don't expect anything special. The first real highlight doesn't show up until Tuesday the 25th of August, and even that one comes with a big caveat.

Right now, through the end of this week and into the weekend, it's all messy. We've got onshore winds, rain showers, and a bumpy, choppy ocean. The swell is tiny and weak, under 3 feet, with combined wave energy barely getting into double digits (10 to 60), so don't bother paddling out unless you just want to sit on a board and get rained on.

The first thing that even gets close to noteworthy is the morning of Monday the 24th. The wind swings light cross-offshore from the SSW, and the surface cleans right up. The swell is still tiny though, a weak 1.6 ft from the north with a period of just 5 seconds combined energy of 13, so it's really just a gentle, clean bump. Not a real session, but maybe a quiet morning paddle.

Now, the one that could be a proper stand-out – if you're an expert – is Tuesday the 25th of August. The morning shows a solid 7.9 ft swell from the north with a 7-second period. That's a big step up, and the combined wave energy is serious at 585. But listen, that's heavy. At 7.9 ft it's strictly for experienced surfers, and it's coming in with a moderate cross-shore wind that will throw some lumpy cross-chop onto it. It's not going to be glassy, but there's real power there if you've got the skill to handle it. After that, the wind swings cross-onshore and the size drops, making it messy again. So that Tuesday morning window is your best bet in the whole 16-day outlook, but it's only for the confident crew.

Overall, the next couple of weeks look pretty poor for quality surfing. There's a lot of wind and rain, and the few bits of clean swell are tiny. The only real energy we see is that bigger, lumpy north swell on the 25th. Don't hold your breath for anything else.

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.
