The Lowdown

Alright, Rusty here, speaking in feet and miles now.

Look, I’ve got to be honest with you – the next 16 days at Arashi Beach are looking pretty bleak. The guidance file tells me this is a rare-breaking spot, and that’s exactly what we’re seeing. We’ve got a massive gap with no real surf on offer. There’s a tiny blip of swell on Friday afternoon, August 14th, but after that, it’s a blank run right through to the end of the month. That’s a solid two-week stretch of nothing.

The water temp is sitting at 82°, which is about average for the time of year here, so that’s not the issue. The problem is the swell. On August 14th, we’re looking at a tiny 0.3 ft wave from the north, with a 13-second period. That’s a long period, which would normally be good for shape, but at just 0.3 ft, it’s barely a ripple. The combined energy is a weak 3, so there’s just no power in the water. The wind is blowing strong offshore from the east at 28 mph, which is clean, but with no swell, it’s a complete waste. It’s going to be glassy and clean, but there’s nothing to ride.

After that, from August 15th right through to August 29th, the swell is completely flat. The combined energy reads zero. The wind stays offshore or cross-offshore, and it’s clean, but it’s just a flat ocean. The spot is exposed to the north-west, and we’re just not getting any swell from that direction at all.

This is a tough one to call. Arashi Beach rarely breaks, and this run proves it. For a beginner spot, you’d want a nice small, clean wave, but there’s nothing coming. The forecast is dead. If you’re a kitesurfer, the strong, clean offshore winds might be your thing, but for a paddle surfer? There’s absolutely nothing to get excited about. I’d say save your energy and check back in a week or two – sometimes the forecasts change, but right now, it’s a write-off.

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.
