The Lowdown
Alright, folks, Rusty here. Let’s get straight into it. It’s pretty grim in the water for the next week or so—everything’s blown out or flat. The main energy is weak to moderate, with the combined swell energy sitting at just 55–239 (moderate) for most of the first week, but the wind’s a mess—cross-onshore or cross at best—and the waves are short-period, mostly 4–8 seconds, meaning junky, unorganized swell. The surf conditions are poor, with scores showing zero for a long stretch. There’s a gap of about 10 days before we get anything vaguely surfable.
Blokken – Water temp is 69°, which is 5° warmer than normal for the time of year—that’s notably warm, so you can leave the thick rubber at home. The best of the whole 16-day window is Thursday 17 September morning. We’ve got a 6 ft swell from the NW, with a 7-second period, which is short but coming with offshore wind from the SE at 6 mph. That’s clean, wind is light, and the combined swell energy is strong at 318—so there’s some punch. The break is inconsistent though, so you’ll need patience. Expect good surf conditions. That’s the standout. The afternoon of the same day goes glassy, but the swell drops to 4 ft and the energy is moderate (135) – still a decent session if you’re around.
Wednesday 16 September morning is also worth a mention: 5 ft from the WNW, 6-second period, combined energy 171 (moderate), and light offshore breeze from the ENE at 6 mph. Clean conditions, but the scores say ordinary – it’s surfable, but not epic.
From Friday 12 September onward, there’s a window of light wind and some small swell, but the size is below 2 ft and the period is 3–6 seconds, so not really worth paddling out for. The water temp data is missing for later days, but we know the early part is warm. For the rest of the second week, the swell shows up again around Monday 21 September with 6 ft from the N, period 7 seconds, and strong energy at 351, but it’s onshore wind from the NW at 19 mph, so it’s messy and blown out. Not a good call.
Standout: Thursday 17 September morning at Blokken – 6 ft NW, offshore wind, clean, strong energy. Go early.
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.
