The Lowdown
Right then, let’s have a look at what’s cooking for Blokken.
To be straight with you, the next couple of weeks are looking pretty grim for a paddle. We’ve got a long dry spell on our hands. The first solid surf worth mentioning doesn’t show up until the end of August, and even then, it’s touch and go. The water’s sitting at 71°F – that’s much warmer than normal for this time of year, which is a bit of a talking point.
Starting Sunday the 23rd, we’ve got a small 3ft swell from the NNW, but the wind is a cross-onshore breeze at 13 mph, and it’s messy. The combined energy is weak, just 97. Nothing to get excited about. Monday and Tuesday are similar – tiny, weak swells with clean-ish conditions but barely a ripple. The energy drops to 36 and then 13. It’s a real flat spell.
Midweek doesn’t offer much hope. Thursday the 27th is practically flat, and Friday brings a bit of bump from the SW, but at 3ft and a short 4-second period, it’s just not going to stand up. By Saturday the 29th, the swell jumps to 7ft, but it’s from the WSW with a strong cross-onshore wind at 22 mph, making it lumpy and messy. The energy is moderate at 431, but with those winds, it’s blown out. That size is also getting too big for beginners.
The best of a bad bunch looks like Monday the 31st of August. The swell drops to 4ft from the west, and for the afternoon we’ve got glassy conditions with the wind going light from the NNW at just 3 mph. The wave comment says “surfable but very ordinary,” and I’d agree. It’s a small, clean wave – about the only moment worth a look if you’re desperate. The combined energy is weak at 57.
Into September, we get a pulse on the 1st with a 5ft swell from the NNW, energy at 198, but the wind is a strong cross-shore, making it lumpy. Not great. The 4th of September shows the best potential for shape: a 5ft swell from the WNW with a gentle offshore breeze from the SSE and clean conditions. The period is a short 6 seconds, so it’ll be a bit crumbly, but that’s the standout. It’s still only a 1 out of 10 on the score. After that, it’s back to choppy, windy conditions through the 6th and 7th.
Honestly, the pickings are slim. For the more experienced surfer, that morning of the 4th of September might offer a few clean but ordinary waves. For everyone else, it’s a long wait. Crowds at Blokken can be a problem sometimes, but with surf this poor, you’ll likely have it to yourself.

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.
