The Lowdown
Alright, Rusty here. Let's have a look at what's cookin'.
Well, I gotta be straight with you, the outlook for Big Wave Bay (sheltered, NE) over the next sixteen days is pretty grim. We're staring down a real dry spell. There’s just nothing rideable for the first week and a half. From Thursday the 30th of July all the way through to Thursday the 13th of August, the swell is tiny and weak, mostly under 1 ft with poor conditions. The combined swell energy is negligible, barely cracking 60 (weak) on the odd afternoon. It’s a long, flat stretch with no real surf on offer.
Now, there's a tiny flicker of hope right at the tail end of the forecast. On Friday the 14th of August, a small bump shows up. We’re looking at a 2 ft swell from the ENE, but here's the kicker – the period is a pitiful 3 to 4 seconds. That’s just wind chop, not a proper groundswell. It’s not going to have any push or shape. The wind will be cross-shore, so it won't be totally blown out, but with that short period and tiny size, it's barely worth paddling out for. It's a real shame because the water temp is sitting at 84° which is about normal for the time of year, nice and warm, but there's nothing to ride.
For the whole sixteen days, there isn't a single standout session. With it being so consistently poor, this kind of blank run isn't unusual for a sheltered spot like this. Even the best-case scenario on the 14th is a real stretch. You'd be better off leaving the board in the car and finding something else to do.
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. 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.
