The Lowdown
Alright, Rusty here. Let’s talk about the surf.
Right off the bat, I gotta be straight with you: there’s nothing on the cards for the next 16 days. It’s a long, flat spell with no real swell to speak of. The first few days of this run are dead calm, with zero wave energy, just a relentless offshore wind. That wind is blowing strong and clean, but with no waves to push, it’s just a waste of good conditions.
We’re looking at a gap that stretches from Monday the 17th of August all the way through to the end of the month. The only tiny pulses of energy show up on Wednesday the 19th of August, with a 0.3 ft swell from the north, but it’s a short period, around 10 seconds, and the combined energy is a measly 2 (two). That’s barely a ripple. The same weak, northerly bump shows up again on Saturday the 29th of August, with a slightly longer period of 13 seconds, but again, only 0.3 ft and a combined energy of 3 (three). It’s not enough to ride.
Arashi Beach is the only spot in the mix, and it’s rated as a beginner wave that rarely breaks. With that in mind, a blank run like this isn’t unusual for this area. The water temp is sitting at 82°, which is about normal for the time of year, so at least the water’s warm if you just want a swim.
Honestly, with the strong, consistent offshore winds and absolutely no swell, the setup here is looking more interesting for kite surfers than for paddle surfers. There’s nothing to paddle into. Keep an eye on the forecasts, though – it tends not to stay this poor for long.
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.
