The Lowdown

G’day, Rusty here. Let’s be straight with you—Blokken’s got a tough run ahead. The next week and a half is mostly a write-off, with barely a ripple and if there is any size, the wind is all over the shop. The first decent glimmer of hope doesn’t show up until Sunday, September 6th, and even then, it’s only just surfable. The real standout window is the morning of Saturday, September 5th, with tiny, clean waves, but it’s a bit of a specialist session. For the most part, you’re looking at a long, dry gap with no real recommendations until that first week of September.

Let’s break it down. We’re stuck in a pattern of poor conditions right through the end of August. Thursday the 27th has almost nothing—0.7 ft at 4 seconds from the north, combined energy a measly 2. It’s just not happening. Friday the 28th through the weekend sees a bump in swell, but the wind is all wrong. Saturday morning the 29th jumps to 6 ft at 6 seconds from the WSW, with a combined energy of 226 (moderate), but a strong cross-shore breeze makes it messy. That’s too big for beginners and blown out.

Sunday the 30th stays messy, Monday the 31st gets a bit of size—7 ft at 6 seconds from the WSW, 305 combined energy—but again, strong cross-shore and cross-onshore winds ruin it. That’s expert-only territory.

Tuesday September 1st and Wednesday the 2nd are still poor, with the swell dropping off and the wind staying up. Thursday the 3rd throws up 6 ft at 6 seconds from the west (251 combined energy), but the wind is still a cross-shore mess. Not worth a paddle.

Now, Saturday September 5th morning is the real standout. The swell is only 2 ft at 7 seconds from the north, combined energy just 22 (weak), but the wind is glassy—dead calm, perfect conditions. It’s tiny, but if you’ve got a log, you’ll be sliding on clean, glassy faces. Crowds are sometimes a problem at Blokken, so you might not be alone. This is the only moment in the whole forecast where the conditions align.

Sunday September 6th morning is the next best—4 ft at 6 seconds from the west (106 combined energy, moderate), with a light offshore breeze from the ESE. It’s clean and surfable, but the swell is short period (6 seconds) so it’ll be a bit crumbly, not a lot of push. It’s a fun, ordinary session, not a standout.

After that, Monday the 7th has a bit of clean 4 ft west swell in the morning, but it’s dropping off fast. From Tuesday the 8th onwards, the swell fades away to nothing, with strong winds again. September 11th Friday morning shows a spike of 6 ft at 7 seconds from the NNE (249 combined energy), but it’s blowing hard onshore from the WNW. That’s a kite-surfing day, not a paddle day.

So, bottom line: if you’re desperate, the glassy morning of September 5th is your best bet for a clean, tiny wave. The 6th of September morning is the only other session that’s actually surfable without the wind trashing it. Otherwise, the region’s on a long holiday. Forecasts can change, but right now, it’s a lean run.

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.
