The Lowdown
Alright folks, Rusty here. Let's be straight about it – the next couple of weeks are looking pretty lean around here. The forecast shows a long stretch of surf that's just not worth paddling out for, with one or two later windows that might be worth a look if you're desperate.
Right now, at Blokken, the water is at 68°, which is 4° warmer than usual for this time of year – a real surprise, feels like a tropical anomaly.
To start with, from Saturday the 12th of September all the way through to Monday the 21st of September, it's a grim run. The swell is small and weak, mostly under 3 ft, with poor quality and messy winds. There's a bit of a spike late in this period – on Saturday the 19th of September afternoon, the combined energy hits 195 (moderate) with a 5 ft swell from the WSW, but the wind is a messy cross-shore at 25 mph, so it's not going to be clean. It's just not worth getting wet.
The real low point is around the 25th and 26th of September, where the swell drops to a tiny 0.3 ft to 0.7 ft. It's basically flat.
The best you're going to get is on Sunday the 27th of September afternoon at Blokken. There's a 5 ft swell from the NW with a 6-second period, and the combined energy is a decent 119 (moderate). The wind is a gentle cross-onshore at 9 mph, so it won't be perfect, but it's the biggest and most energetic surf in sight. Just keep your expectations in check – it's the only standout because everything else is so poor. The rest of that week is just a slow fade out.
Honestly, for the next two weeks, the only real tip is to stay patient. Sunday the 27th of September afternoon is your best bet, but don't expect magic.
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.
