G’day, I’m Rusty. Let’s get into it.

Right off the top, we’re looking at a pretty grim stretch for Blokken. The next week and a half is mostly a write-off, with a big gap of poor conditions. The water is sitting at 68°, which is much warmer than normal for this time of year—you’ll feel that difference straight away, almost like a late-summer hangover in July.

The first real glimmer comes on the morning of Monday, 20th July. It’s not much, but there’s a tiny 3ft swell from the NNW, period around 6 seconds, with light cross-offshore winds. The energy is weak at 56 and the wave comment says “surfable but very ordinary.” Honestly, it’s barely a paddle, but it’s the first clean-looking window in over a week, so if you’re itching, you’d take it.

The real standout, the only one worth setting your alarm for, is the morning of Friday, 24th July. That’s the one. Swell jumps to 8ft from the W, period 7 seconds, and the combined energy is a solid 539—moderate, pushing strong. The wind is light and offshore from the NNW, so it’ll be glassy and clean. Now, that size is getting into expert territory; over 8ft and it’s specialists only, but 8ft is still doable for strong intermediates. The swell direction matches the ideal NNW exposure perfectly. Blokken is inconsistent, so a morning like this doesn’t come often. No crowds data to say for sure, but with a rare score like that, expect a few locals to sniff it out.

After that, the afternoon turns a bit cross-on and the swell drops to 6ft, still decent but not the same magic. The rest of the 16 days? Dead. Gap after gap. Nothing worth chasing.

Overall, it’s a long wait for one morning of promise. If you’re keen, pencil in that Friday 24th July morning and hope the forecast holds.

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.
