Table - best surf conditions forecast for Big Wave Bay over the next 16 days.
Hey folks, Rusty here. Let's break down the next couple weeks at Big Wave Bay. Honest truth – it's a quiet stretch. This spot is normally pretty consistent for beginners, but most days we're looking at tiny, weak surf or messy conditions. There are a couple of short windows that might be worth a look, but nothing that gets me stoked.
Kicking off Friday the 10th: an ESE swell at 5 feet with a long 17-second period – that's solid energy (1352), but the wind is light cross-onshore and the report mentions marginal tide or something. Not clean. Water temp is a warm 84°, about average for the time of year.
Saturday the 11th morning is your best early call. The swell drops to 3 feet from the ESE, still a nice 15-second period (358 energy), and the wind swings to a light cross-off. It'll be clean, small, and fun for a beginner or anyone just wanting a lazy session. After that, things go flat and crummy – Sunday through Tuesday the 14th and beyond into the following week, we've got almost nothing. Tiny ripples and messy wind.
The next glimmer is Sunday the 19th morning. Another 3 feet from the east, 7-second period, cross-off breeze – clean but weak (154 energy). Surfable, but ordinary. Then Monday the 20th morning goes cross-off but with only 1 foot – barely a bump.
Late in the window, around Wednesday the 22nd and Thursday the 23rd, we see a pulse of bigger swell – 6 feet Wednesday afternoon, 8 feet Thursday morning – but the wind is cranking from the east, cross or cross-on, and the energy values are high (968 Thursday morning). Problem is it's messy, lumpy, not clean. For a sheltered bay, that onshore wind kills it. Honestly, if you've got a kite, those days might be more fun than trying to paddle into a lumpy 6-foot closeout. For surf, forget it.
The last possible window is Friday the 24th morning: a 3-foot easterly swell with a light west cross-off. Clean again, but small. After that, it's back to tiny or nothing.
So bottom line: if you're keen, hit Saturday the 11th early, or maybe Sunday the 19th or Friday the 24th mornings. Otherwise, this stretch is mostly a dud. Forecasts can change, but right now it's slim pickings.
Rusty.

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.

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.
