The Lowdown
Alright folks, Rusty here. Let’s be straight with you: this outlook is a tough one. We’ve got a 16-day window ahead, and honestly, the surf just isn’t cooperating. There’s a long stretch of nothing worthwhile, so don’t get your hopes up too early.
Right from the start, Friday the 17th of July, we’re looking at a tiny, weak 2 ft swell out of the north-northwest with a short, lackluster 4-second period. The combined wave energy is a measly 13, which is nothing to write home about. To make matters worse, the wind is howling onshore at 12 mph, making it a total mess. The water temp is a whopping 71°, which is 9° warmer than usual – that’s very unusual, almost like a bath. But it’s not going to save the surf.
This pattern of poor conditions (light gray skies, weak onshore winds, and ankle-biters) just keeps rolling through the weekend and into the next week. On Sunday the 19th, the swell bumps up to 5 ft from the NNW, and the energy hits 233 – that’s moderate energy, for sure. But the wind is a fresh 19 mph cross-onshore, so the description says it all: “fresh cross-onshore and lumpy.” That’s not surfable fun, that’s a washing machine on the beach.
The rest of the 16 days is a total washout. Blokken is an inconsistent spot, and this stretch proves it. From Monday the 20th all the way through Saturday the 1st of August, the swell is tiny, under 3 ft, often with periods of 4 to 6 seconds. The wind is nearly always onshore or cross-onshore, often fresh to strong, and the wave energy drops to single and double digits. It’s just not happening.
There are no standout days, no hidden gems, no windows of glassy perfection. If you’re a kite surfer, the strong cross-shore winds on the 26th of July (near gale at 31 mph) might look interesting, but for a paddle surfer, it’s a hard no. The setup is more for kites than boards on a day like that.
Keep your board waxed and your eyes on the next forecast. Sometimes it just doesn’t break for a while, and this is one of those times. The forecasts can change, but right now, we’re looking at a blank run.
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.
