The Lowdown
Alright, this is Rusty. Let's be straight up about Big Wave Bay. Lookin' at the next sixteen days, and I gotta be honest with you, it's a tough stretch. The whole period is a flat spell.
We start off with nothing. Thursday the 3rd, Friday the 4th, all through the weekend and into next week... it's a real bummer. The water temperature is sitting at a warm 84°, which is pretty normal for this time of year, but there's just no energy to play with. You're looking at tiny dribbles, all under 2 ft, and the combined energy is super low. It's not happening.
Now, there is a tiny flicker of hope. On Friday the 11th, we see a pulse of swell push in. The morning has waves hitting 5 ft from the east, with a period of 7 seconds. The combined energy jumps to 269 (moderate wave energy), so there's some push there. The wind is blowing light from the north-northeast, keeping things fairly clean. But even then, the conditions are described as "surfable waves but very ordinary conditions," so it's not exactly a standout.
After that little bump, it fades back to nothing. The energy drops right off again and stays tiny through the second week. The water temp anomaly is a 0.1°, so nothing unusual there, just flat and quiet. There's really no standout session to point to across these two weeks.
So, the honest truth? For a beginner-friendly, sheltered spot, this is a blank run. It happens. Forecasts change, but right now, there's just no surf to get excited about.
Stay patient,
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.
