The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this 16-day window for Arashi Beach is about as flat as a millpond. The finder is showing zero swell for almost the entire run, and the guidance confirms it’s a beginner spot that rarely breaks. There’s simply nothing to get excited about in the surf department.
We’ve got a long dry spell from now, Thursday 20 August, all the way through to the end of the month. Day after day of clear skies and strong offshore or cross-offshore winds, but with no wave energy to work with – the combined energy is a flat zero (0) for every single entry. The wind is howling from the east at 22 to 28 mph, which would be perfect for clean surf if there was any swell, but it’s just blowing over a dead ocean. The water temp sits at 83.1°F with a normal anomaly of 1.1°F, so that’s about average for the time of year, but it’s not going to help the waves show up.
The first flicker of something happens on Tuesday morning 1 September, when we see a tiny 0.3 ft north-northwest swell with a 13-second period, giving a combined energy of just 3. That’s a whisper, not a wave. And it’s gone by the afternoon. After that, it’s back to zero for the rest of the forecast. For a spot that’s already hard to break, this is a real blank run. If you’re a kite surfer, those strong, consistent east winds might make the bay look interesting, but for paddle surfing, it’s a no-go.
Hang in there – forecasts can change, but right now, there’s nothing to paddle for.

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.
