Sponge bay Surf Forecast and Surf Report

Alright, Rusty here. Let’s have a look at what Sponge Bay has in store for us over the next couple of weeks.

We’ve got a bit of a slow start, but a couple of absolute crackers are on the horizon. The water is sitting at 55°, which is a bit colder than usual for this time of year. The early action is all about a nice groundswell from the SSE that shows up on Monday the 14th, with clean 5-foot waves and that glassy morning wind. The wave energy is moderate (711), and while it's not huge, the conditions are set up for a really pleasant session.

Monday afternoon drops off a bit with a cross-shore wind, so make the most of the morning. The next few days are pretty average – small, ordinary surf with light breezes, nothing to get excited about. Thursday the 17th has a tiny bit of clean swell in the afternoon, but it’s very weak with only 76 units of energy.

Friday the 18th is a complete write-off; strong cross-onshore winds and heavy rain will have you staying on the beach. Saturday the 19th morning is a bit messy, but the afternoon cleans up with a nice little 3-foot swell from the ESE and a slight air, making for a decent surf. The energy is moderate (295).

Now, here’s the standout. Monday the 21st of September. That morning is the pick of the whole outlook. A solid 6-foot swell from the SSE, with a very long period of 15 seconds, creating a huge amount of energy (1807). The wind is light and cross-offshore, leaving the waves clean. This is a proper groundswell, and at this size it’s tipping into expert territory, so it’s not for the groms. The afternoon stays solid at 5 feet with an even longer 19-second period (1825), though the cross-shore wind might put a slight ripple on it.

After that, the swell drops away and the wind turns ugly for a few days. Wednesday the 23rd sees onshore wind making a mess of things, and by Thursday the 24th, a huge 10-foot swell from the S is predicted, but the break is simply too big to handle – that’s kite-surfing territory, not for paddling.

Towards the end of the run, Saturday the 26th morning looks fun – clean 6-foot waves from the S with an offshore wind and moderate energy (588). The afternoon gets choppy. The final Monday on the 28th has a 6-foot swell but a short period of 7 seconds, so it’ll be a bit lumpy and less consistent.

Overall, the best session is hands-down Monday the 21st of September morning. It’s a clean, powerful groundswell with light wind – a true standout. The Saturday the 26th morning is a solid second option for a more relaxed surf.
