Bronte Beach Surf Forecast and Surf Report

Alright mates, Rusty here. Let’s chew the fat on Bronte Beach. It’s a long outlook with a lot of wind and size to work through, but there are a couple of sessions that could be worth the effort.

The first week is a proper mixed bag of fluff and then a solid, but tricky, pulse. The water is sitting at 64°F right now, which is about average for this time of year, so no nasty surprises there.

We start off with a bit of a waiting game. The first couple of days are a write-off. Saturday the 5th and Sunday the 6th are flat to weak with poor surf, and the wind is either cross or onshore. Not worth getting wet.

Things start to look up on Monday morning, the 7th. The swell picks up to 5ft from the SSE, with a period of 10 seconds. The combined energy is moderate (548). The wind is a light cross-offshore from the NW, which will keep it clean. This is a proper window of opportunity. The waves will have some punch, but at 5ft, it’s still manageable for a lot of crew. The standout here is the wind: light and clean, which is a major positive.

Tuesday the 8th is a big jump in size, but it’s a tough call. The morning sees a solid 10ft swell from the S, with a period of 10 seconds. The energy is very strong (2607). This is big, powerful stuff. It is only for experienced surfers. The wind is a moderate cross-off from the SSW, so it’s clean, but the size is the main factor. It’s a beast of a swell. The afternoon hangs around 8ft, but the wind swings to a cross-on, making it messier.

Wednesday the 9th is a washout with strong onshore winds, and Thursday the 10th is another day of big, powerful swell (10ft in the morning, 8ft in the afternoon) with cross-off then cross-on wind. Again, expert-only territory and the wind isn’t ideal.

The next real standout comes on Friday morning, the 11th. The swell drops to a more manageable 6ft from the S, with a period of 10 seconds. The energy is moderate (787). The wind is a light cross-off from the SW, and the forecast says “expect very good surf conditions.” This is the best day of the whole run. It’s clean, it’s got some juice, and the wind is playing ball. If you can only get one session, this is the one.

After that, things get inconsistent. Saturday morning the 12th is glassy with a 4ft S swell, which would be a nice, clean, smaller option. Sunday morning the 13th is also glassy with a 3ft S swell, but the period is a very long 12 seconds. That’s a groundswell, and at Bronte (a beach and reef setup), a long period S swell can be a bit too straight, making it a bit fat. Still, for a clean, small day, it’s a good option.

From the 14th through the 18th, it’s mostly poor with onshore winds and small, weak swell. There’s a gap of several days with no real recommendations. The energy drops right off, down to around 86 on the 15th.

A couple of interesting pulses show up in the second week. On the morning of the 16th, we get a solid 8ft swell from the S, with a period of 10 seconds and very strong energy (2400). But the wind is a cross-shore, so it’s going to be a bit of a battle. Less promising. Then on the 19th, the morning has a 4ft S swell with a long 12-second period, but the wind is a gentle cross-shore, not ideal.

So, the pick of the crop is clear: Friday morning, the 11th of September, for the best combo of clean conditions and decent size. Monday morning the 7th is a close second for the clean, building swell. The big days on the 8th, 10th, and 16th are for the hardcore crew only, and even then the wind might not be perfect.

Rusty.
