The Lowdown

Alright, Rusty here, let’s talk about the surf window ahead for Big Wave Bay.

Right off the bat, I gotta be straight with you – the next 16 days are looking pretty grim for a proper paddle session. The first real chance of anything that even resembles a wave is a while away, so expect a long, flat start. We’re looking at a solid gap with no recommendations for the first few days.

Things are dead quiet right through Thursday the 27th and Friday the 28th. Tiny, weak little swells, mostly poor surf conditions. Don’t bother getting the wax out.

We get a tiny bump of energy on Sunday the 30th morning – a 4ft swell from the east-northeast, but the period is a shocking 5 seconds and the wind is a fresh cross-onshore. It’s lumpy, choppy, and combined energy is weak (94). That’s not surf, that’s just messy water.

Monday the 31st afternoon sees a pulse of energy jump up: a 6ft swell from the east with a 6-second period. The combined energy is moderate (279), but the wind is onshore and there’s a risk of thunderstorms. It’s a no-go.

Now, here’s the one tiny window that’s even worth mentioning. On Tuesday morning, September 1st, we have a bit of a standout – but manage your expectations. A 6ft east swell with a short 6-second period, but the wind is a light cross-offshore from the north-northeast. This is a rare moment of clean conditions. The break itself is fairly consistent, but it’s a beginner spot and sheltered from the north. At this size (6ft), it’s starting to get a little too big for the beginners. The water temp is about average for the time of year. If you’re an intermediate looking for a clean but slightly lumpy push, this is your only shot in the whole outlook. Expect a few other surfers out there, as crowds are possible.

After that Tuesday morning flurry, it dies again. We drop down to tiny, weak, and poor conditions for the rest of the first week and into the second week. By Saturday the 5th of September, it’s flat with zero energy. There is a glassy morning on Monday the 7th with a tiny 1ft swell, but it's not enough to ride. The rest of the period stays small, weak, and mostly cross-onshore.

Honestly, the setup here looks more interesting for a kite than a paddle for 99% of this forecast. The one clean morning on the 1st of September is the singular highlight. The long-range stuff is just too far off and uncertain to get excited about.

Rusty, signing off.

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.
