The Lowdown
Alright, Rusty here again. Let’s break it down in feet and Fahrenheit.
Honestly, mate, it’s a pretty bleak stretch ahead for Blokken. The entire 16-day window is a real struggle. There’s a long gap right from the start, and honestly, you’re looking at day after day of poor surf conditions. The only time the waves even get close to being worth a look is right at the very end, and even that’s a marginal call.
The water is sitting at 69°F – that’s much warmer than normal for this time of year, a good 5°F above average. Feels like a warm bath with no waves.
The first real sign of life doesn’t show up until Monday, September 7th. On the morning of the 7th, there’s a 4ft swell from the WSW, with a moderate offshore breeze from the S. That’s clean, but it’s only a combined energy of 86 – weak. It’s not going to be any great shakes. The afternoon picks up a bit, with a 6ft WSW swell (energy 248, moderate), but a light cross-shore breeze puts some small ripples on it. The forecast score is marginal, so it’s a gamble. Could be a few fun ones if you’re not fussy and the tide plays ball.
That’s really the only standout, and it’s a pretty weak one. For a spot that’s exposed to a NNW optimum and inconsistent, you’d want a better aligned swell. This WSW swell is not its best direction. If you’re desperate, Monday the 7th afternoon is your best bet, but keep your expectations low.
The rest of the run is a write-off – wind is onshore or cross-shore most days, with short-period slop under 3ft. A few days in the second week show a little pulse, but the wind ruins it. Saturday, September 5th morning has a tiny 0.3ft swell with glassy conditions, but it’s barely a ripple.
Honestly, for Blokken, this is a normal blank run. It just doesn’t stay poor for long, but this time it’s a long, dry spell. Forecasts can change, but right now, there’s nothing to get excited about.
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.
