The Lowdown
Alright, grab a seat… I’ve looked over the next 16 days for Arashi Bay Reef, and I gotta be straight with you—there’s basically no surf on offer. Nothing. Nada. The whole run is a write-off for any kind of half-decent wave. That first record kicks off on August 16th with zero combined swell energy (0), and it’s just the same story right through until the very end of the month. If you’re checking the water temp, it’s sitting around 82°F which is about average for this time of year – no anomaly to speak of – but the waves just aren’t there.
Now, I see a tiny puff of life on August 20th Thursday afternoon, with a 0.3ft north swell showing up, 9 second period and only 2 total energy, but it’s still marked as "poor surf conditions." Same story again on August 26th Wednesday afternoon, where a 1.0ft north swell creeps in with a short 6 second period and energy of 6. And then again on August 28th Friday afternoon and 29th Saturday afternoon, we’re back to 0.3ft north groundswell with a 10 second period, but only 2 of energy. None of these blips come close to rideable. The wind is screaming from the east and east-northeast at 19 to 28 mph the whole time—mostly strong offshore and clean-looking, but so clean it’s basically a lake with no push. That’s a problem. It’s not just small; it’s *non-existent* for paddle surfing.
Because the swell is so absent and the wind is so strong, this setup actually looks way more interesting for kite surfing than for paddle surfing. The water’s going to be glassy-looking but flat.
Arashi Bay Reef is a spot that rarely breaks, and unfortunately, this 16-day window is a perfect example of why. There’s no standout day, no hidden gem. It’s just a blank run. For this area, a dry spell like this is more normal than not, so don’t let it kill your stoke. Tomorrow’s another day.

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