Bonza Bay Surf Forecast and Surf Report

G’day, I’m Rusty. Let’s break down what Bonza Bay has in store over the next couple weeks. It’s a river mouth spot, open to south swells, and the water temp is 66°, right around average for this time of year – no surprises there.

Right now, Sunday the 6th, it’s pretty grim. A 0.8m (3ft) SSW swell with a very long 23-second period, but that ESE wind at 20 km/h (12 mph) is cross-onshore and choppy. The combined energy is 969 (moderate), but the conditions are poor – not worth it. Afternoon sees 1.5m (5ft) but still cross-onshore and marginal.

Monday the 7th is a write-off. Swell around 2.1m (7ft) from the south, period 15 seconds, but the wind’s howlin’ ENE at 35 km/h (22 mph) – lumpy and messy. Tuesday the 8th is similar: 1.7m (6ft) east swell, short 9-second period, cross-onshore winds, and choppy. Energy’s moderate (696 and 612), but it’s marginal at best.

Then we hit a dry patch from Wednesday the 9th through Saturday the 12th. Swell’s tiny – 0.5m (2ft) or less – or when it shows up, the wind’s no good. Combined energy stays under 100 or just barely into triple digits (62, 44, 79, 152). It’s flat and messy for days.

But Sunday the 13th is the gem. That morning we’ve got a solid 2.3m (8ft) E swell with a 9-second period, and the wind is glassy – dead calm. Combined energy jumps to 1423 (strong), and it’s rated excellent for experienced surfers. That afternoon stays clean with a light cross-offshore NNE breeze at 15 km/h (9 mph) and the swell at 2.0m (7ft), energy 1014. This is the one. Crowds are ‘sometimes’ at Bonza Bay, so you might see a few others, but that glassy mornin’ is worth the early alarm.

Monday the 14th drops off – 1.2m (4ft) and 1.7m (6ft) but the wind’s cross-off or cross, only marginal. Tuesday the 15th through Thursday the 17th keeps up the poor-to-marginal trend with onshore winds and chop. Nothin’ special.

Long-range: Saturday the 19th brings a monster 3.5m to 4.0m (12ft to 13ft) SSE swell with combined energy of 4099 to 5487 (very strong). The morning’s glassy, but it’s flagged as too big for Bonza Bay – expert-only if you’re keen, but more likely a mess. Sunday the 20th still huge at 3.0m (10ft) with strong cross-offshore winds, but again, probably too much.

The second week’s real standout is Monday the 21st: a 2.5m (8ft) SE swell, period 10 seconds, combined energy 1160 (strong), and glassy in the mornin’. That’s excellent for experienced surfers. It’s further out, so keep watch.

So to sum up: Sunday the 13th is your best bet – glassy, solid swell. Monday the 21st is a promising long-range option. Everything else is forgettable.
Rusty.
