Alright, Rusty here again. Let’s talk about Big Wave Bay for the next couple weeks. I’ll level with you—it’s looking rough. There’s really nothing worth chasing. We’ve got a long stretch of flat or nearly flat surf, so if you’re hoping for a score, you might be out of luck.
The one tiny glimmer is Saturday morning the 11th. We get a little ESE swell at about 3ft, with a long 15-second period. That’s a nice long period, brings some shape, but the combined energy is still weak at 358. Water temp is about average for July at 84°F. Winds are light from the W, cross-off, and it’s clean. For a sheltered, beginner-friendly spot like this, that’s the only window. But it’s still pretty ordinary.
After that, it’s all downhill. Saturday afternoon the wind picks up SW at 12 mph and the swell drops to 2ft. Sunday the 12th has tiny 0.6ft waves with a moderate cross breeze. From Monday the 13th all the way through Saturday the 26th of July, it’s mostly flat—0.3ft or less—with onshore winds, rain, and thunderstorms. There’s a spike on Sunday the 19th with 3ft swell, but the wind is screaming 31 mph from the NE, making it a total mess. The 20th has clean-ish conditions with strong offshore winds near 37 mph, but the swell is only 2–3ft with a short period. Not worth it.
If you’re into kite surfing, those windy days around the 19th and 20th might be more fun. For us paddlers, it’s a washout. This sort of flat spell isn’t unusual here, so don’t stress too much—forecasts can turn, but right now there’s nothing to get worked up about.
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.
