The Lowdown
Alright, Rusty here. Let’s be straight with you – this is one of those outlooks where I wish I had better news. We’re looking at a solid 16-day run starting now, but honestly, the surf is going to be a tough sell for most of it.
Overall Pattern
The main issue is the wind. For the first week or so, every time we get a tiny pulse of swell, the wind either rakes it onshore or blows straight into it, making a mess of things. We're mainly looking at tiny, weak waves. The combined swell energy rarely gets above 30 or 40 (moderate wave energy), often sitting in the single digits or the low 20s (weak wave energy). That’s not a lot of grunt.
The first real glimmer of something rideable comes on Tuesday 11 August in the morning. Blokken sees a small 2ft N swell rolling in with a period of 7 seconds. The real treat is the wind – a gentle cross-offshore breeze from the ENE. That’ll clean the face up nicely. Water temp is about average for the time of year. It's small, but it’s the only session in the first five days that’s even worth paddling out for.
After that, things drop right off again. From Wednesday 12 August through to Saturday 15 August, it’s a total desert. We’re talking flat, barely a ripple, and even when a puff of swell arrives, the wind is either moderate cross-on or strong cross-on. That Saturday, 15 August, has a 3ft N swell, but a strong breeze from the N at 25 mph makes it a complete mess – that’s more of a kite-surfing setup than a paddle session.
We get a small pocket of cleaner conditions on Sunday 16 August morning with a light cross-offshore, but again it’s only 2ft of N swell with a short 6-second period. It’s not going to blow your mind.
The real standout – if you’re a patient optimist – looks to be Tuesday 18 August. The swell directions shift, and we get a 1ft N swell, but the period stretches to 9 seconds, which means a bit more shape and energy behind it. The wind is a light cross-onshore, but at that size, it might just be clean enough at the right tide. Very small, but the best of the second week.
After that, the pattern gets messy again. We have cleaner cross-offshore winds on the 20th and 22nd, but the swell is tiny and short-period. The final few days of the run, 23-25 August, are dominated by onshore or strong cross-onshore winds again, with the swell barely registering.
The Best on Offer
If I had to pick just one, it’s Tuesday morning, 11 August. That 2ft N swell with the clean cross-offshore breeze is your best bet for the whole sixteen days. It’s not big, but it’ll be the most fun. The standout for a touch more period and better shape is Tuesday 18 August, but you’ll be scratching for anything rideable.
It’s a flat, windy run. Not a classic Blokken stretch. Hang in there.
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.
