Sandy Mouth Surf Forecast and Surf Report

G’day, Rusty here, and I’ve got to be straight with you – this 16-day window is a tough one for Sandy Mouth. The forecasts are constantly throwing up poor surf conditions, with cross-onshore winds and choppy line-ups sticking around for most of the run. The water temp is sitting at 66°, which is much warmer than normal for this time of year – a solid 5° above average, so you’ll be comfortable in a spring suit or maybe even boardshorts if you’re tough enough.

Right now, starting Sunday morning the 30th of August, we’ve got a small 4 ft swell from the west, but that 15 mph SSW wind is cross-on and it’s making things messy. That pattern sticks around for days. Monday morning the 31st sees a bump in size to 8 ft from the west, period hits 10 seconds, and the combined energy is moderate at 985, but it’s still cross-on and lumpy. That’s getting into the too-big-for-beginners range, and with the wind, it’s not great for anyone.

We get a bit of a break on Tuesday afternoon the 1st of September – the wind swings to onshore but lightens up, swell drops to 3 ft from the west, and the energy is weak at 129. Still, it’s not clean, and the wave comment says it’s poor. Wednesday and Thursday the 2nd and 3rd keep the same story: moderate to fresh cross-onshore winds, swells around 4 ft to 6 ft, and energy stays moderate (176 to 401). The best of a bad lot might be Thursday morning the 3rd – onshore wind but only 15 mph, with 5 ft west swell and 8-second period – but it’s still labelled as poor.

Friday the 4th of September has a solid 7 ft west swell with 7-second period, energy at 507, but it’s onshore wind and lumpy. Too big and blown out for a good session. The weekend of the 5th and 6th sees the swell drop right off – Saturday morning the 5th has 4 ft from the WNW, 10-second period, with a gentle cross-on breeze, but by Sunday afternoon the 6th we’re down to 2 ft, glassy conditions, but only 42 energy. That’s tiny, even if it’s clean.

The first half of the following week is even smaller. Monday the 7th of September has 1 ft west swell, and Tuesday the 8th has a 25 mph onshore gale with 2 ft to 3 ft – that’s more of a wind-swept mess than surf. The only real standout comes late on Thursday the 10th of September. The afternoon sees a 4 ft west-southwest swell, 8-second period, and the wind drops to glassy – 3 mph from the southwest. The energy is moderate at 175, and the wave comment says “surfable waves but very ordinary conditions.” That’s the best we’ve got, but it’s still nothing to write home about. After that, Friday the 11th and Saturday the 12th go back to onshore and cross-onshore winds, with swells around 4 ft to 5 ft.

The final days, the 13th and 14th of September, are tiny again – 1 ft to 2 ft, glassy at times, but with weak energy (31 to 57). The 14th has a 1 ft west swell with a long 11-second period, and glassy conditions, but it’s just too small to get excited about. Overall, this is a blank run – there’s no real quality surf on offer in the entire 16 days. The consistent west swell direction is there, but the wind and conditions just aren’t lining up. For now, I’d say save your energy – forecasts can change, but this one’s looking pretty grim.

Rusty.
