Sponge bay Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what Sponge Bay is cooking up over the next couple of weeks.

Right now, the surf is pretty slim. We’ve got a bit of a flat spell to kick things off. From Sunday the 12th right through to Thursday the 16th, it’s mostly small and weak, with the odd tiny wave but nothing worth getting wet for. The combined energy is way down in the dumps (37 to 312), so you’re looking at knee-high slop at best. The water temp is sitting at 57°F, which is about 1°F cooler than average for this time of year, so it’s a touch nippy but nothing crazy.

The real action starts to build on Friday the 17th. That morning, we’ve got a solid ESE groundswell pushing in at 5ft with a 15-second period. The wind is light and cross-offshore, so the wave quality is going to be excellent. The combined energy jumps up to 964, which is a solid moderate pulse. This is the first real standout window. It’s a beginner-friendly spot, but with the swell bumping up to 5ft by the afternoon, it’s starting to get a bit more push, so less-experienced surfers should be mindful. The wind stays light and cross-off, so it’ll be clean all day.

Saturday the 18th holds similar size (5ft) and the same long period, but the morning is the call. By the afternoon, a strong SSW wind kicks up to 22 mph, turning it into a lumpy, cross-onshore mess. Get your session in before lunch.

Now, the big one. Sunday the 19th is the standout of the entire outlook. The swell picks up to 6ft in the morning, then 7ft in the afternoon, from the SSE with a very long period of 17 to 20 seconds. That’s genuine groundswell. The wind goes offshore all day, light to gentle, and the combined energy hits 2505 to 2616, which is strong. This is excellent surf, but it’s firmly in the experienced surfer zone. The long period will make it bend and wrap nicely at Sponge Bay, but expect some lulls between sets. Crowds are possible here, so keep an eye out.

The swell eases a bit into Monday the 20th and Tuesday the 21st, with 4ft to 5ft waves and still decent periods. The wind gets a bit tricky, with cross-onshore and cross-shore conditions, so the quality drops off. Still surfable, but nothing special.

Then we hit a rough patch from Wednesday the 22nd through to Friday the 24th. The swell gets huge – 8ft up to 12ft – but it’s blown out. Strong onshore winds from the SSE and ESE are hammering the coast, making it a total mess. The combined energy is through the roof (1357 to 3768), but the conditions are poor. This is definitely more of a kite-surfing setup than a paddle-surfing one. Steer clear unless you’ve got a 5m kite.

The end of the outlook brings a glimmer of hope. On Saturday the 25th, the swell drops to 8ft, but the wind is still cross-onshore, so it’s choppy. However, Sunday the 26th is a cracker. The morning shows 8ft of ESE swell with glassy conditions – a light SW breeze of just 3 mph. The energy is 1449, and the wave quality is rated excellent for experienced surfers. That’s your second standout. It’s a big swell, but those glassy conditions will make it epic for the crew who can handle it.

Finally, Monday the 27th keeps the run going with 7ft waves from the east and clean, cross-offshore winds. The energy is 1623. Another excellent session for the experienced bunch.

So, to wrap it up: the first week is slim pickings, but Friday the 17th and Saturday the 18th mornings are your early windows. The absolute standout is Sunday the 19th – that’s the session to circle on the calendar. Then, if you’re brave, Sunday the 26th morning with glassy 8ft waves is a serious reward for waiting out the stormy middle week.

Rusty.
