The Lowdown

Alright, let’s get into it. The surf window’s been pretty quiet, so I’ll level with you: the next few days aren’t worth paddling out. We’ve got a long stretch of small, messy, or flat conditions, and it’s not until late in the run that things look a bit more interesting. Let’s break it down.

The first half of the outlook is a washout. Through Thursday the 10th and into the following week, Blokken is mostly dealing with weak, short-period swell from the NW or SW, all under 3ft. The wind is cross or onshore most days, and the energy numbers stay in the weak range — mostly between 12 and 56 (weak wave energy). The best you’ll see is a few clean windows on the Monday the 14th morning (1ft from the NNW, light cross-off wind), and Tuesday the 15th morning (1.0ft, 12 seconds period, clean) — but the swell’s just too small to do much with. The water temp’s about average for the time of year, nothing unusual to report.

We get a little bump around Wednesday the 16th September — the swell height climbs to 5ft from the NNW, with moderate wave energy around 126, but the wind is a fresh cross-onshore from the N and NNE, so the surface is lumpy and messy. This isn’t the kind of day you get excited about. It’s still poor surf conditions across the board.

The energy really starts to build from Saturday the 19th September afternoon — swell from the WSW at 5ft with 166 (moderate wave energy), but the wind is moderate cross-onshore and the period’s short at 6 seconds. Sunday the 20th sees the swell pushing 6ft from the WNW (282 energy, moderate), again with cross-onshore wind. Still not clean, but you can feel it building.

Now here’s where it gets interesting — but only for the brave. Monday the 21st September morning and afternoon sees the biggest swell of the window: 8ft from the NW, with a period of 7 seconds and combined energy hitting 552 and 559 (strong wave energy). This is solid, heavy surf — but the wind is a fresh to strong cross-shore from the SW and WSW, making for a lumpy, messy, cross-chop. The size alone puts this well into expert territory, over 8ft. It’s also not a clean wave, and the period’s still short, so it’s more raw power than finesse. If you’re an experienced surfer and don’t mind some wind bump, this is the most interesting window — but honestly, the conditions look more like a windswell event, and for most people this will be more of a kitesurfing setup than a paddle-surf session.

After that, Tuesday the 22nd drops off quickly back to 3-4ft, and the rest of the forecast tails off into tiny or flat conditions through to the end of the month.

So here’s the truth: there’s no standout day in the near-term. If you’re desperate, Monday the 21st has the most size and energy, but it’s not clean and it’s big. For clean, lined-up waves, we just don’t get that combo in this window. It’s a tough run for Blokken, but forecasts can change, and it never stays flat forever. Keep an eye on it.

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.
