Big Rock Surf Forecast and Surf Report

Alright, Rusty here. Let’s talk about what’s in store for Big Rock. I’ll lay it out straight – the next sixteen days are a real test of endurance. It’s a long stretch of tiny, weak surf, and the forecast is brutally consistent in that it’s consistently poor for most of the time. The first bit of swell that’s even worth mentioning doesn’t show up until Friday the 15th of August, and even then, it’s touch and go.

The water temperature is sitting at 75°F, which is 7°F warmer than usual for this time of year. That’s a real oddity, something you’ll definitely feel.

Starting off, we’ve got a tiny pulse on Friday morning, the 31st of July. The swell is 4ft from the SSW with a nice long 14-second period, and the combined energy is moderate (617). The wind is light and offshore from the W, so it’ll be glassy clean. But the wave comment says it’s marginal, and the scoring tells the story – it’s not worth getting your hopes up. After that, it all goes flat and messy. From Friday afternoon all the way through to Thursday the 14th of August, the swell stays well under 3ft, with most readings between 1ft and 3ft. The periods are consistently long, from 13 to 20 seconds, which for a reef like Big Rock would normally be a great sign, but there’s just no grunt behind it. The combined energy readings hover between 127 and 504, which is weak to moderate. The wind is mostly light and offshore or light cross-onshore, so the conditions are clean, but there’s absolutely no push. It’s a frustrating run of flat, clean, unrideable surf.

Now, the best on offer in this whole window is the morning of Saturday the 15th of August. We finally see a 3ft swell from the SW with a 16-second period. The combined energy is a solid moderate (538), and the wind is light and offshore from the W. That’s the recipe for a clean, lined-up wave. It’s still not big, but it’s the standout. The afternoon of the same day holds similar size and swell direction, though the wind picks up a little to a gentle breeze. It’s still offshore, so it’ll be clean. This is the only real window where you’d want to paddle out. It’s a long way off, over two weeks away, so treat it as a promising one to keep an eye on, but don’t lock your plans in yet.

For the rest of it? Honestly, it’s more of a kite-surfing setup for the most part – small swell, clean but weak energy. The crowds at Big Rock are often present, so on that one decent day, expect a few locals out. If you’re an advanced surfer, the lack of size means you’ll be fighting for nothing. Beginners might be okay on the 15th because the swell is under 5ft, but the long period and reef setup mean it’s probably not the best place for a learner.

So, a long dry spell, then a single, hopeful morning on the 15th. It’s a waiting game.

Rusty.
