Bonza Bay Surf Forecast and Surf Report

Alright, let’s break this down. Bonza Bay is a river mouth, facing south, and right now you’ve gotta be patient. The first few days are rubbish — messy winds, dodgy tides — but there’s a real glimmer of hope if you’re willing to wait.

Friday the 10th starts things off, but don’t bother. 3ft of south swell with a 14-second period gives you plenty of push (2335 energy), but a moderate breeze out of the WSW is blowing cross-off and making a mess. Water temp is about normal for this time of year. Saturday and Sunday are no better — lumpy, cross-onshore junk with smaller swell. Leave the sticks at home.

Monday morning the 13th is your first real hope. The wind goes glassy — dead calm out of the NE at just 3 mph. Swell drops to 6ft from the ESE, period at 8 seconds, energy at 584. That glassy morning will be clean and fun, especially on a longboard. Monday afternoon gets a little chop, so make the dawn session.

Tuesday and Wednesday hold around 5ft to 6ft, straight east swell, periods creeping up to 10 seconds. Winds stay light and cross or cross-off, keeping things rideable. Energy is moderate (452 to 554). Not a standout, but steady.

Then Thursday the 16th afternoon throws a curve — swell direction swings to the SSW with a 13-second period, energy jumps to 781, but height is only 4ft and wind is cross-on from the east. Tease.

The next week goes flat. From Friday the 17th through Monday the 21st, it’s tiny swell (2ft to 4ft), poor conditions, and mostly onshore or strong cross winds. A real dry spell.

Wednesday morning the 22nd surprises — glassy calm again, 0 mph from the north. Swell is 5ft out of the east, 9-second period, energy at 445. Clean and rideable. Thursday morning the 23rd gives you another glassy session: 4ft from the SSW, 11-second period, energy at 489. That longer period means better shaped waves at a river mouth. Two dawn patrols to aim for.

But the real standout, the one that’ll get you up early, is Saturday the 25th morning. 7ft of solid SSW groundswell with a very long 17-second period. Energy is massive at 2574 — that’s strong, powerful stuff. Wind is light and cross from the NE at 9 mph, keeping it clean. That size and period is for experienced surfers only; over 8ft it’s expert-only, and 7ft with that energy will be thumping. Long period at a river mouth can be magic, but it’s a long-range call — promising, but not guaranteed.

Crowds here are sometimes an issue, so if that Saturday morning holds, expect a crew.

Overall, this 16-day run is a slow burn with a few clean windows and one serious swell on the horizon. Pick your moments.
