The Lowdown
Alright folks, Rusty here. Let’s see what’s cooking for the next stretch.
Gotta be straight with you – the outlook for Big Wave Bay is a real slow burner. There’s a big dry patch right off the bat. From Sunday the 19th all the way through Saturday the 26th, it’s practically flat. Poor surf conditions day after day. The water is a warm 84°, which is about average for the time of year, nothing unusual.
The first real sign of life pops up on Sunday the 26th of July. The morning is glassy, with a tiny 0.3ft swell from the SE, but the period is 11 seconds, and the combined energy of all swells directed here is only 9 – weak. It’s a hint, but not a session.
Monday the 27th of July afternoon shows a bit more. A 2ft swell from the SE, but with a short period of 5 seconds, so it’s just bumpy windswell. The combined energy climbs to 102 – moderate. Wind is cross from the SSW at 20 km/h, so it’ll be choppy. Not your day.
The real standout is Tuesday the 28th of July, and the morning is the clear winner. We’re looking at a clean 3ft swell from the ESE, with a 14-second period – that’s proper groundswell with good shape. The wind is light cross-off from the SW at 15 km/h, keeping the surface tidy. The combined energy sits at 269, which is solid. This is the window. The surf is still manageable for most, but that long period will make the waves a bit more powerful. Crowds are possible, so get out there early. The afternoon bumps up to 3ft with a 16-second period, but the wind goes cross-shore at 20 km/h, so it won’t be as clean.
Wednesday the 29th still offers a clean morning with a 2ft ESE swell and a 13-second period, but the energy is dropping. By Thursday the 30th, the swell shifts to the SW and the period crashes to 6 seconds – back to weak, messy stuff. And from Friday the 31st onward, we’re back to tiny 0.3ft dribbles. The second week just fades out.
If you’re only going to paddle out once, make it Tuesday morning the 28th of July. That’s the one.
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.
