The Lowdown
Alright, folks, let’s break it down for Blokken over the next 16 days – and I’m sorry to say, it’s a total dud. Not a single session worth chasing. The water’s running real warm, about 71°F, which is a good 9°F above normal for July, but that’s where the good news ends.
Blokken is a spot that only fires when the swell comes from the NNW, and we’ve got that direction, but the wind is hammering it from the north and northwest almost every day – onshore or cross-onshore, making everything choppy and lumpy. Swell heights bounce from a tiny 0.7ft up to a few chest-high sets around 6ft on July 23 Thursday morning, but that 6ft comes with a 7-second period and 19 mph cross-onshore wind – just a mess. The combined energy hits 276 (moderate) but the quality rating is zero. Short period means weak, crumbly waves.
Even the calm morning on July 30 Thursday – glassy conditions, 2ft from the north – sounds nice, but it’s only 2ft with a 7-second period, and the wave comment says “poor surf conditions.” Energy is only 32 (weak). So not worth it.
From July 18 through August 2, it’s all poor. The best you could hope for is a tiny, clean wave on July 30 morning, but it’s barely rideable. Blokken is inconsistent anyway, and when the wind is against you, it’s a total washout. This kind of blank run happens here – don’t hold your breath.

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.
