The Lowdown
Alright, Rusty here. Let’s cut straight to it.
The next 16 days are a tough watch for Blokken. The run of flat or junk surf is long, and the first proper swell showing some kick doesn’t come until way out there on August 15th, and even that comes with serious caveats. Don’t get too excited early on.
For the first week and a half, it’s a write-off. Tiny heights, short-period slop, and onshore winds dominate. Friday 31st July is straight-up hopeless: 0.7ft to 2ft of weak, short-period swell with onshores. Saturday 1st August morning goes glassy with a light WSW breeze, but the swell is a pathetic 1ft at 5 seconds – barely a ripple. That pattern carries through the whole first week: consistent only in being inconsistent and poor. The best early look is Tuesday 4th August afternoon, with a clean cross-offshore breeze and 1ft at 9 seconds, but the energy is still weak (25). Not worth paddling out for.
A shift happens around Saturday 8th August. The swell jumps to 5ft on Saturday morning, directed from WSW, but the wind is onshore from the NW, and the period is short at 6 seconds. The combined energy hits 133 (moderate), so there’s some push, but the quality is ruined by the onshore wind. That trend of middling swell with messy wind holds through the rest of the second week.
The one standout worth mentioning, and it’s a dodgy one, is Saturday 15th August morning. Swell rises to 5ft from the NW with a 7-second period, and the combination energy climbs to 237 (moderate-strong). That’s the biggest swell on the cards. But here’s the catch: the wind is cross-shore from the SW at 16 mph, creating a cross-chop, and for Blokken the optimum swell direction is NNW, not NW. This setup looks far more interesting for kite surfing than paddle surfing – the wind will mess up the face, and the period is short, so the waves will be lumpy and hard to ride. Too big for beginners (over 5ft) and not clean enough for experts given the cross-chop.
Water temp is about average for the time of year. Blokken remains inconsistent across the board. A blank run like this is fairly normal for the area in this stretch.

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.
