The Lowdown
Alright folks, Rusty here. Let's be straight with you – this is one of those outlooks where you might want to keep the board in the bag for a while unless you're happy just sitting out the back in a strong offshore breeze.
Right now, and for most of the next 16 days, we’ve got a real flat spell settling in over Arashi Bay Reef. This is a tricky reef break that rarely breaks, and honestly, it’s not showing any signs of life for the foreseeable future. We’re looking at a massive gap starting from Thursday the 13th of August, running all the way through to the end of the outlook on the 28th, with basically zero riding waves on offer.
Most of the time the wind is hammering out of the east at 22 to 31 mph. It’s clean, sure, but it’s a strong offshore that just pushes everything flat. The energy reading is a total zero – 0 – which tells you there’s just no swell getting in. The combined energy of all swells directed here sits at zip. Water temp is sitting around 83° which is about average for the time of year.
You’ll see a couple of tiny bumps around the 18th and 21st of August – we’re talking 0.3 ft from the north with a short period – but that’s barely a ripple. The waves are poor. Given the persistent wind and lack of any real swell height, this setup honestly looks more interesting for kite surfing than paddle surfing if you’re desperate to get on the water.
There are no standout days here. There is no best on offer. This is just a long, flat, wind-affected run for Arashi Bay Reef.
Stay patient. Forecasts can change.
Rusty.

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.
