The Lowdown

G’day, Rusty here. Well, let’s be honest with yourselves. We’re looking at a pretty bleak 16-day stretch for Blokken. The first week-plus is a write-off, with almost no energy and a bunch of junky wind. The only real glimmer of hope comes right around the middle of the month, and even then, it’s not a world-beater. The local water is sitting at 71°F and that’s a solid 7°F warmer than usual – that’s a massive anomaly, and you’ll feel it if you get in.

The first solid sign of life is Friday morning, August 7th. We’ve got a tiny 3ft of swell from the NNW, with a period of 8 seconds. It’s not much, but the light SSW cross-offshore wind will keep it clean. Energy is weak at 78. It’s surfable, but you’ll be competing for scraps.

Then it dies again. The next week is a flat, bumpy mess. There’s a long gap of basically nothing from the 8th through to the 13th. A few mornings offer knee-high slop, but the winds are mostly junk. You’re not missing anything.

Now, here’s the one to watch: Thursday morning, August 14th. We finally get a bit of a pulse. The swell bumps up to 4ft from the WNW, with a 5-second period. It’s short-period, windswell, but it’s something. The key here is the wind: it’s dead glassy. Slight air, no wind. That’s the magic ingredient. The energy is moderate at 97, and the water is still warm. It’ll be small, but clean and lined up. This is your best chance for a few peelers. The afternoon gets messy again with a cross-onshore, so make the most of the morning.

After that, the swell tries to build again. On Monday afternoon, August 17th, the size jumps to 7ft, but the period is a weak 7 seconds and the wind is howling onshore at 25 mph. That’s a recipe for close-outs and chop. The energy is strong at 447, but it’s all mush. The following Tuesday morning sees similar size at 7ft, but again, it’s riddled with a fresh cross-shore. This looks way more interesting for the kite crew than for us paddle surfers. Unless you’re an expert and don’t mind a beating, give it a miss. The period is just too short for that size.

So, the standout is that Thursday morning session. It’s not epic, but it’s clean. After that, it’s all a bit of a lottery. The long-range stuff around the 17th and 18th is promising in size, but the quality is going to be terrible. We’ll need a change in the wind to make that work.

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.
