The Lowdown

Alright folks, Rusty here. Let's have a look at what's on the cards for Blokken over the next couple of weeks.

First thing's first, this is a bit of a slow burner. The forecast is pretty grim for the first week, with a lot of wind and small, messy surf. You're looking at a solid seven-day stretch of poor conditions, with only a small window of interest near the end. The water temperature is about average for the time of year, so nothing to write home about there.

Wednesday, September 16th, is where things start to get a little more interesting. After a long run of nothing, the morning brings a 4ft swell from the NW with a cross-offshore breeze from the SE. It's clean, but it's only a 6-second period, so it's a bit short and weak, with combined energy of only 95. It's surfable, but don't expect any world-class pits. The afternoon gets a bit better with that same 4ft swell from the NNW, but the wind drops out completely – glassy conditions. The combined energy picks up a touch to 117, but it's still a pretty weak, ordinary wave. This is definitely the best on offer, but it's a "get what you can" kind of session.

Now, the real standout is looking like Thursday, September 17th. The size drops to 3ft, but the period jumps to 8 seconds in the morning and 10 seconds in the afternoon. The combined energy is moderate (119 and 157). The problem is it's a bloody cross-shore wind, which will put a lumpy chop on the face. This is a classic case of swell energy being there, but the wind is ruining it. If you're an expert and can handle the chop, it might be worth a look, but for the average punter, it's a pass.

The rest of the second week is a mix of tiny waves and onshore winds, with a few clean mornings on the 21st and 22nd of September. The 21st has a 4ft NNW swell with a 7-second period and a clean cross-offshore breeze from the E, with combined energy of 135. It's rideable, but still nothing to get overly excited about. The gap between the 16th and the 21st is noticeable, with a lot of junk in between.

Overall, don't get your hopes up too high. It's a period of waiting, with a brief, clean window on the 16th being the only real highlight. The surf is generally weak and the wind is a constant battle.

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.
