Bonny Hills Surf Forecast and Surf Report

G’day, it’s Rusty here, and I’ve been staring at the charts for our stretch of coast, trying to find the window where it all comes together. It’s not going to be a week of endless pontoons, but there are a couple of mornings that have the potential to be absolute magic.

To kick things off, let’s get the water temp sorted. For the first decent surf, we’re looking at conditions that are about average for this time of year, so the wetsuit you’ve been using is spot on. Nothing weird going on there.

The next few days are pretty forgettable, to be honest. Friday and Saturday are all cross-shore breezes and short-period slop, with wave energy pretty weak (56 to 179). It’s the kind of stuff that has you checking your phone more than the surf. Sunday isn't much better, and that 5ft on the afternoon is a messy cross-onshore chop.

The first real sign of life is Monday, September 7th, at Bonny Hills (Bonny-Hills). The morning is looking glassy with a light southerly air and a jump in energy (396). We’ve got 5ft of south swell at 10 seconds, and it’s clean. For a point break, that’s a fun, user-friendly size. This is a decent place to start, so if you can sneak out for a session, that’s your first chance.

After that, it gets a bit messy again through Tuesday and Wednesday. There’s swell around, but the winds are all over the shop with rain and chop, so it’s not worth getting excited about. The energy is moderate (between 231 and 379), but the quality isn’t there.

Then we hit the bigger stuff. Thursday, September 10th brings a serious jump in size—8ft in the morning building to 10ft by the afternoon—but that’s way over the comfort zone for most. With strong cross-onshore winds and very strong energy readings (1099 to 2260), that’s going to be a wild, dangerous mess. Unless you’re charging, stay away. The following Friday, September 11th, is still big (7ft to 8ft) with a long 11-12 second period, but the winds are still cross-shore, so while the energy is strong (1146 to 1478), the surface will be a bit of a battle.

There’s a gap of a few days after that, with a drop back in size and poor winds, so don’t expect much from the 12th to the 15th.

Now, for the standouts. There are two windows that look truly special.

First, Wednesday morning, September 16th. It’s got that ‘glass’ wind state with almost no air, and we’re looking at 4ft of south swell at 11 seconds and a solid moderate energy reading (344). The forecast says “expect good surf conditions.” For a point break like this, that’s going to be clean, lined-up, and perfect for a longboard or a funboard. This is a classic morning session.

But the real gem is Friday morning, September 18th. The wind is dead calm, 0 mph, and it’s glassy. The swell is a solid 7ft of south swell with a 9-second period, and the energy is strong at 664. This has “expect very good surf conditions” written all over it. This is the pick of the entire 16 days for those who can handle a bit of size. By the afternoon it bumps up to 8ft with an 11-second period and light offshore winds, and the energy jumps to 1294, but that’s more for the experienced crew. For the average punter, that Friday morning glass-off is the one.

Sadly, the run ends with a bump. Saturday, September 19th looks like it gets blown out by a strong 28 mph southerly, so you’ll want to have your fun on Friday.

So, to sum it up: the best options are the clean, glassy mornings on Monday the 7th, and especially Wednesday the 16th and Friday the 18th. If I had to pick one, it’s that Friday morning, September 18th. It’s going to be worth the wait.

Take it easy, Rusty.
