The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this stretch ain’t looking like much of a party. We’ve got a long, dry run ahead with nothing on offer that’s worth paddling out for. The whole 16-day window is a bust for surf, so don’t be holding your breath.
The only break on the radar is Big Wave Bay. It’s a sheltered beginner spot, and the swell direction is coming from the east, which is off its optimum NE. The combined swell energy is weak to moderate at best, getting up to 512 (moderate) on Friday the 11th, but that’s all noise. The wind is a problem – cross-shore and cross-onshore straight through, with a nasty chop and lumpy mess. By the 13th, we’ve got a risk of t-storms and strong winds pushing things into the “kite surfing” zone. The wave period is short, mostly under 8 seconds, so no real power or shape. Even the long-period 18-second blip on the 19th and 20th is tiny, only 1 ft, and won’t break cleanly here.
There’s a gap of nothing worth recommending from the 11th all the way to the 26th. The water temp is about average for the time of year, nothing unusual. Consistency is fairly consistent here, but it’s just consistently poor. A blank run like this isn’t totally abnormal for the area, but it’s a real bummer.
Stay dry, gang. The forecast can always change, but right now, it’s a no-go.
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.
