The Lowdown

Alright, Rusty here. Let's break it down.

Right off the bat, I gotta be straight with you – the next couple of weeks look tough. We've got a long, dry spell ahead. The first bit of surf that’s even worth talking about doesn't show up until Sunday the 6th of September, and even then it’s a mixed bag. Before that, from now right through until that Saturday the 5th, it’s mostly blown-out, messy, and just plain ugly. There’s some size, sure – we see a peak on Friday the 4th with swell hitting 7 ft from the west with 7-second period, and the energy pushing up to 427 (moderate). But the winds are a nightmare, strong and cross-onshore, churning up the surface. That’s not a day for a paddle, that looks like a kite surfer’s playground at Blokken, honestly. The water’s running real warm right now – 69°F – which is much warmer than normal for this time of year, but you won't be enjoying it in that slop.

Then we get a quiet spell. Swell drops right off. Monday the 7th brings some clean conditions from a light southerly and cross-offshore wind, but the swell is tiny, only 0.7 ft. Glassy, pretty, but nothing to ride. That sets the tone for the rest of the outlook. For days after that, we’re looking at small, weak pulses. On Thursday the 10th of September, we get a hint of life with a 2 ft swell from the NNW (6-second period) and clean-ish cross-off winds, but again, the energy is just 27 (weak). Not worth getting excited about.

The only real standout? If you’re desperate, keep an eye on Sunday the 6th of September. The morning shows a small 2 ft swell from the NNW, period 7 seconds, and a light southerly cross-offshore breeze. The energy is weak at 55, but it’s the cleanest the place will look all week. It’s not a big day, but it’s surfable and the wind will be kind. By the afternoon it goes glassy with almost no swell, so the morning session is your only shot. Just keep your expectations in check – Blokken is inconsistent, and this run proves it.

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.
