The Lowdown
Alright, Rusty here. Let's talk about Arashi Beach.
Straight up, it’s looking grim on the wave front for the entire 16 days, from now through September 23rd. We’re looking at a long, flat stretch. The first week is totally empty, nothing but heavy wind. The only tiny pulses of energy show up between the 10th and the 14th, and I mean tiny—a 0.3ft north swell with combined energy barely reaching 3 to 5. Even with a period of 12 to 16 seconds on those days, that’s not enough to make a dent. After that, it’s right back to zero.
The wind is relentless. Easterly winds howling at 18 to 28 mph, often a strong breeze. It rips offshore for most afternoons, making the ocean look clean as a whistle, but it’s just a flat glass with nothing on it. Mornings are cross-offshore, which would be fine with waves, but there are none. This whole setup screams kiteboarding, not surfing. Water temp is pretty average for this time of year, nothing wild.
There are absolutely no standouts. The closest you get to a "maybe" is the morning of September 14th or 16th with a 0.3ft, 13 to 16-second groundswell from the north, and a slightly lighter, fresher breeze around 18 mph. But I wouldn’t paddle out for it. This break rarely breaks in the first place, so a long flat spell like this is just par for the course.
A full blank run is normal for this area when the wind won't quit. Could change, but right now, don’t bother waxing up. At least the paddle out would be a breeze.
Rusty.

Information about the Arashi Beach Surf forecast
The above surf forecast table for Arashi Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Arashi Beach can be found by selecting the local surf guide option on the grey menu. Our Arashi Beach 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 (Arashi Beach) 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 Arashi Beach 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.
