Alright, let me take a look at what we’ve got for the next couple of weeks.
Honestly, it’s a pretty grim run for the most part. We’ve got a long stretch of weak, onshore-slapped surf and stormy weather that’s gonna keep things real quiet. The first real opportunity doesn’t even show up until Friday morning, July 10. Before that, it’s just thundery showers and choppy, tiny waves – not worth paddling out for.
So the big standout here, and really the only window worth getting excited about, is the morning of Friday, July 10 at Big Wave Bay. We get a clean 5ft SE swell with a long 18-second period – that’s proper long-period groundswell, packing some serious energy (1414). The wind is glassy, dead calm, so the surface will be buttery smooth. This is the best on offer by a long shot. The water’s sitting at 83°F, about average for this time of year. Keep in mind this spot is sheltered and a beginner-friendly setup, so with the swell just over 5ft, it might be a touch too much for absolute beginners, but it’ll be a fun, clean wave for everyone else. The SE direction isn’t a perfect match for the optimum NE, but with that quality and wind, it’s still gonna be good.
Friday afternoon gets a little cross-onshore and drops a notch in quality. Saturday and Sunday, July 11 and 12, the swell collapses into nothing – we’re talking ankle-snappers with clean but weak wind.
Then we run into a massive gap from Sunday, July 12 all the way through to the end of the third week of July. It’s just tiny, choppy mess, day after day. There’s a brief spike on Wednesday, July 22 in the morning: a 10ft E swell crossing with moderate wind (1192 energy), but the period is a short 8 seconds and the wind is cross-shore and lumpy. That one rates as marginal at best, and for a beginner-friendly break, 10ft is well into expert-only territory with that messy wind. Not one I’d paddle for.
Overall, save your energy for Friday morning, July 10. That’s your wave. The rest of the window? A good time to wax your board and watch the horizon.

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.
