Bonza Bay Surf Forecast and Surf Report

G’day, Rusty here, checking in on the stretch ahead for Bonza Bay. This is a river mouth setup, exposed to the south, so it can get a bit of push when the swell lines up. The water’s sitting at about average for the time of year, nothing too wild temp-wise. We’ve got a mixed bag of conditions coming, so let’s wade through it.

The first real chance to get wet comes Monday morning, July 13, with a cloudy sky and a light cross-breeze from the ENE at 6 mph. The swell is 7.2 ft from the east, with a period of 8 seconds, so it’s a bit short and bumpy, pushing 1102 units of combined energy. Not the cleanest—marginal feel to it, but it’s surfable. The afternoon sees the wind pick up a notch, dropping the swell to 5.6 ft, and the chop gets a bit more messy.

Tuesday, July 14, is where it starts to improve. The morning is clear, glassy offshore from the SSW at 3 mph, with a 6.2 ft easterly swell and a period of 9 seconds. The combined energy is 700 units, and it’s clean—really clean. This is a solid window for a session, with the river mouth likely handling the east swell well. The afternoon turns cross-on, so morning is the pick.

Wednesday, July 15, the swell drops to 4.6 ft, still east, and the wind is cross-shore in the morning with a glassy feel from the SW. The energy is down to 387 units, so it’s a bit weaker. Afternoon gets messy with a stronger cross-on breeze, so not much to chase.

Thursday, July 16, the morning is small at 3.6 ft with a cross-breeze, but the afternoon flips—clean, cross-off wind from the NNE at 6 mph, and a long-period groundswell from the SSW at 14 seconds with 685 units of energy. The waves will be lined up, but point breaks and reefs will love this period—at a river mouth, it might be a bit straight, but with that clean wind, it’s worth a look.

Friday, July 17, the morning has a fresh 19 mph cross-off from the WSW, but the swell is only 3.0 ft from the SSW with a long 14-second period. The energy is 566 units, and it’s clean, but the size is tiny. The afternoon gets a bigger 6.2 ft bump from the SSW, but the wind is strong and cross, making it lumpy.

Saturday, July 18, the swell is up to 6.9 ft from the south with a 13-second period, but the wind is cross and strong from the ENE at 12 mph, giving a chop. 1645 units of energy, but the quality is marginal. The afternoon wind is even stronger.

Sunday, July 19, the swell drops to 4.3 ft from the SSE, with a moderate cross-breeze. Not much to write home about.

Monday, July 20, the morning is a standout: clear, offshore from the WNW at 9 mph, with a 2.6 ft SSW groundswell at 14 seconds. The energy is 344 units, so it’s small, but that offshore wind and long period will make it clean and fun. The afternoon is a write-off with a strong cross-breeze.

Tuesday, July 21, brings a 19-second period swell from the SSW at 3.3 ft, but the wind is onshore in the morning and cross-on in the afternoon with a big 1966 units of energy. The quality is poor.

Wednesday, July 22, the swell is 5.9 ft from the SSW with a 16-second period, but the wind is a fresh cross-breeze, making it lumpy. The energy is 1557 units.

Thursday, July 23, the swell builds to 7.2 ft from the south with a 13-second period, and the wind is cross from the SSW at 12 mph. The energy is 1734 units, but it’s a bit messy.

Friday, July 24, the swell drops to 4.6 ft from the south, with a light cross-breeze. It’s okay but not special.

Saturday, July 25, the swell is 3.9 ft from the SSW, with onshore winds in the morning and afternoon. Poor.

Sunday, July 26, we get a big pulse—13.1 ft from the SW with a 14-second period, and 8438 units of energy. But the wind is cross-on from the east at 19 mph, with a risk of thunderstorms. This is too big for the river mouth, and it’s lumpy. The afternoon drops to 9.8 ft, but it’s still too big and messy.

The real standout here is Tuesday, July 14, morning. That glassy offshore, 6.2 ft east swell, and clean conditions are the best on offer. The other bright spot is Monday, July 20, morning, with that offshore wind on a long-period groundswell. Keep an eye on Thursday, July 16, afternoon for the clean, long-period SSW swell, but the river mouth might make it a bit straight.

Overall, the first week has a few good windows, but the second week is more hit-or-miss, with
