Sponge bay Surf Forecast and Surf Report

Alright, Rusty here with the lowdown on Sponge Bay. Let's get into it.

Alright, so the outlook for Sponge Bay over the next couple of weeks is a bit of a mixed bag. We’ve got some promising windows of clean, long-period groundswell, but they’re separated by stretches of junk that aren't worth paddling out for. The water is sitting at 55°F which is a bit colder than normal for this time of year, so don't forget the booties if you're heading out early.

The first real standout comes this Friday the 21st of August. Friday morning is looking tidy with a clean 2ft swell from the SSE, with a very long 16-second period. That kind of period means the wave quality will be solid, with proper shape and energy. The combined energy is moderate at 460, and with a light 6 mph cross-offshore breeze from the NW, it’ll be clean as a whistle. It’s a beach and reef setup, so the long period might make it a bit straight at times, but for a beginner-friendly spot, this is about as good as it gets. Friday afternoon builds to 4ft from the same direction, with the energy jumping up to 691. Still clean with a light breeze. This is the pick of the whole forecast.

The next real highlight doesn’t roll around until Friday the 28th of August. After a week of ordinary conditions and onshore junk, we get a proper offshore wind from the NNW at 9 mph on Friday morning, cleaning up a 4ft SSE swell with a 14-second period. The energy is strong at 581. The winds hold offshore for the afternoon too, with a 3ft clean swell. This is a solid window for a proper session.

Looking further out, Tuesday the 1st of September has a morning window with a clean 3ft SSE groundswell (14-second period) and a light offshore breeze from the NNW, carrying 373 in combined energy. It’s a solid option, but it’s a week and a half away, so keep an eye on it.

There’s a big gap in the middle of the period, from the afternoon of the 22nd all the way through to the 27th, where the conditions are either blown out or just too weak to bother with. The wind turns onshore and the swell quality drops right off.

The 3rd of September brings a bigger push of swell, hitting 5ft from the south, but with a strong SW cross-onshore wind at 15 mph and a short 7-second period, it’s going to be a lumpy, choppy mess. That’s more of a kite-surfing setup than a paddle session.

The last few days of the forecast, the 5th of September, offer some small, clean 2ft waves with a gentle offshore, but the energy is weak at 89. Surfable, but nothing to get excited about.

So, to sum it up: Friday the 21st of August is your best bet, hands down. The long-period swell, light wind, and clean conditions will make it a beauty. The Friday the 28th of August is your next solid window with a proper offshore breeze. The rest is mostly waiting for the next pulse.
