The Lowdown

Right then, Rusty again, with the same picture but in feet and Fahrenheit.

Let's cut to the chase – this forecast is a real heartbreaker. Blokken is the only break showing anything, and for the best part of two weeks, that something is absolutely nothing. From Sunday the 9th of August all the way through to the early hours of Monday the 24th of August, it’s a flat-out drought. The swell barely reaches knee-high, the period is short and weak, and the wind is mostly cross-onshore or onshore from the NW and NNW. The wave energy numbers are pitiful and every session is stamped "poor surf conditions". It's the kind of outlook that makes you want to take up golf.

There’s one shimmer of light, but you’ve got to be patient. Monday the 24th of August morning finally brings a pulse of energy. We’re looking at a 5ft swell out of the WSW with a period of just 6 seconds, so it’s short-period, windswell stuff. The combined energy climbs to 129, which is actually moderate and the best we’ve seen all outlook. The wind is the real winner here – dead glassy with a light breeze from the NE, so the surface will be clean as a whistle. Water temp is about average for the season. The report says "surfable waves but very ordinary conditions", but after two weeks of nothing, a clean, rideable waist-to-chest high wave is a total blessing.

Just remember, Blokken is an inconsistent spot, and with a short-period swell like this, the waves will be a bit fat and lack that proper groundswell push. It won’t be too big for most surfers, but beginners might find 5ft a handful. And because it’s the only break with anything, expect company – crowds are possible here.

So mark it in your calendar: Monday the 24th of August, pre-dawn session at Blokken. The swell direction from the WSW matches the optimum NNW offshore wind, so the setup is right. It won’t be perfect, but after a fortnight of flatness, it’ll feel like a dream.

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.
