Alright folks, Rusty here. Let’s be straight with you – this forecast is a tough one to swallow. We’re looking at a real flat spell with nothing rideable for the next 16 days. The whole outlook is a write-off for any decent waves.

We start off with tiny, weak leftovers on Sunday the 12th at Big Wave Bay. We’re talking about 0.7ft of swell from the ESE with a 12-second period, but the combined energy is a measly 14 – that’s basically nothing. The wind is a cross-off, so it’s clean, but there’s just no power to work with. The water temp is sitting at 83°, which is about average for this time of year.

Then the next week is pretty much a wasteland. There’s a brief spike on Tuesday morning the 14th with a 5ft swell from the ENE, but it’s got a short 7-second period, making it weak and crumbly. The combined energy hits 324, which is moderate, but the wind is cross-off and clean. The problem is, that wave is too straight and gutless to hold any shape. It’s a beach break here, so that short period offers no real ride.

Through the rest of the week and into the next, it’s just tiny dribbles. The combined energy figures are all in the single or double digits – weak stuff. Even when the wind turns offshore on Monday the 20th with 2ft from the ESE, the energy is only 68, and by the afternoon, the wind is howling at 28 mph from the WNW. That’s strong offshore, but it’s so clean it’ll be hard to even paddle into the tiny waves. A setup like that, with strong wind and small surf, honestly looks more interesting for kite surfing than paddle surfing.

After that, we’re back to flat, with combined energy dropping to zero or near-zero for days. There’s a long gap from the 22nd through the 27th with nothing worth mentioning. The point is, there are no good surf options in this 16-day window. It’s one of those blank runs that happens for this area. Surf forecasts can change, but as it stands, you’re better off finding something else to do.

Information about the Big Wave Bay Surf forecast

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