The Lowdown
Right, folks, it’s Rusty here. Let’s just get this straight off the bat: for the next 16 days, we’re looking at a proper drought. The only wave on the menu is Arashi Bay Reef, and it’s a tough one to get excited about. This reef rarely breaks, and the forecast is showing it’s staying true to form. There’s a massive gap right from the start, with no real surf to speak of until we get into the second week.
The first real hint of anything comes around Thursday, 11 September, and even then it’s barely a whisper. We’re talking a tiny 0.3ft wave from the north, with a period of 11 seconds. That’s a long-period groundswell, but with an energy reading of just 2, it’s weaker than a cup of tea. The water temp is sitting at 83.1°, right about average for this time of year, so no surprises there.
The real problem is the wind. Thursday morning, the 11th, it’s ripping out of the east at 25 mph, cross-offshore. It’s clean, sure, but that’s a strong breeze, and it’s going to make paddling into that tiny bump a real chore. By the afternoon, the wind swings more east-northeast at 28 mph, straight offshore. It’s clean, but it’s also blowing so hard it’ll be tough to even get into the wave. This pattern just repeats itself day after day: clean, but with a punishing offshore wind.
Friday, 12 September, is more of the same. 0.3ft, north, 10-second period, 2 energy. The wind is still cross-offshore in the morning at 22 mph, and then offshore in the afternoon at 25 mph. It’s a grind.
Saturday, 13 September, offers a sliver of hope. Still 0.3ft, north, but the period drops to 9 seconds. The energy is still a pathetic 2. The wind is cross-offshore at 22 mph in the morning. It’s just not enough.
After that, we hit a dead zone. From Sunday, 14 September, right through to the end of the outlook, the swell flatlines. There’s nothing. Just zero. The wind continues to blow, but without any swell, it’s a complete washout. There’s a tiny 0.3ft north swell on Wednesday, 16 September, with a 9-second period and 2 energy, but it’s the same old story: cross-offshore wind at 22 mph. It’s not worth getting out of bed for.
The bottom line is this: there’s no standout session here. Not one. The only break on offer, Arashi Bay Reef, is inconsistent and rarely breaks, and this forecast proves it. The combination of tiny, weak swell and strong, onshore winds makes this a write-off. If you’re a kite surfer, the strong, clean offshore wind might look interesting, but for us paddle surfers, it’s a hard pass. The forecast can change, but right now, this is a blank run.

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.
