The Lowdown

Alright, this is Rusty. Let’s have a look at what’s cookin’ – or not cookin’ – for Arashi Bay Reef over the next couple of weeks.

To be straight with you, the 16-day window starts off dead calm, flat, and frankly, a bit grim. We’re talking a solid block of days from Monday the 10th all the way through to the morning of Monday the 17th with absolutely no surf on offer. Zero. Nada. The combined swell energy is sitting at 0 for most of that stretch.

The wind, though, is a constant presence. It’s blowin’ fresh to strong out of the east and east-northeast, hitting 25 to 31 mph. That’s putting it straight offshore for this spot, and the water will be glassy clean – but you can’t paddle into what isn’t there. A few of the afternoon sessions even read as “near gale” on the 12th, so that’s kite-surfing territory, not paddle surfing.

Now, at the very tail end of the outlook, there’s a tiny flicker. On Monday, the 17th of August, we finally see a pulse – a 2 ft swell from the north, with a period of 6 seconds. That’s short-period windswell, and the combined energy is only 17 – weak. Water temp’s sitting at 82°, which is pretty much normal for this time of year (anomaly of only 0.4°). Even then, the Tuesday afternoon on the 18th shows just 0.3 ft from the north.

Arashi Bay Reef is a tricky one anyway – it rarely breaks, and it’s an advanced-only reef setup. Even when that tiny north pulse shows up, the offshore wind stays strong and clean, but the swell is just too small and weak to be worth paddling out for. Crowds are sometimes an issue here, but with surf like this, you’ll have the place to yourself – because nobody’s out.

So, the honest truth: there’s nothing worth chasing. The first real surfable day might not even land in this window. A blank run like this isn’t unheard of for the area. Stay hopeful, though – 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.
