The Lowdown
Well, folks, it’s Rusty here, and I gotta tell ya – this stretch is looking pretty grim. We’ve got a solid 16-day window, from now through to the start of September, and the sad truth is there’s just nothing on offer at Arashi Bay Reef. The entire forecast period is a bust – no rideable swell to speak of, with wave heights all showing as flat or a measly 0.3 ft at best. The water temperature’s sitting at a warm 83°F with an anomaly of 0.7°F, so that’s pretty much average for this time of year, but that’s the only thing that’s not a letdown.
The wind’s blowing hard out of the east and east-northeast, mostly in the strong breeze to near gale range, 35 to 50 km/h (22 to 31 mph). It’s offshore or cross-offshore, so it’s clean, but with zero swell to work with, it’s just a tease. The combined wave energy is zero or barely a whisper (0 to 3), and the swell period is short or missing. Sure, the reef’s a rare break, and it’s exposed to the NW, but nothing’s coming. For the advanced crew, it’s a total write-off – even the occasional northerly 0.3 ft ripples with a 13-second period on the 31st of August won’t get you wet. The whole 16 days is a flat, windy gap. It’s a tough one, but sometimes the ocean just shuts down. Keep an eye on the charts, though – it won’t stay this way forever.

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.
