The Lowdown
Alright folks, Rusty here. Let’s have a look at the Bommie Peak forecast.
This is a solid run of swell for the advanced crew. Bommie Peak is a reef break, and it’s very consistent, so you can rely on it to produce. The water temperature is sitting at 84°, which is about average for this time of year. We’ve got a long fetch of groundswell lining up, so let’s get into it.
The real standout kicks off on Saturday, September 19th. That morning we’ve got a 4ft swell from the SW with a very long period of 18 seconds, and the wind is glassy – total glass. The combined energy is strong (1542). That is going to be a special dawn patrol for the experienced surfer. The afternoon builds to 5ft from the SW with a 17-second period and a clean light breeze, and the energy jumps up to (2002). That is the pick of the whole window: big period, clean conditions, and a heap of power.
The run continues into Sunday the 20th with clean, moderate offshore wind from the SE and a 6ft SW swell at 16 seconds. The energy is strong (1684). That’s a great size for an expert-level reef, but at 6ft, it’s getting into the zone where beginners should sit this one out. The offshore wind will have it grooming nicely.
Monday the 21st keeps the quality high with light offshore wind in the morning, 6ft SSW swell, and a 14-second period. Another clean day.
The swell dips a little mid-week, but Wednesday the 23rd is a gem. Wednesday morning brings moderate offshore wind from the SE with a 5ft SSW swell at 16 seconds. Then Wednesday afternoon goes glassy again with a 5ft SSW swell at 15 seconds. That light offshore and glassy combo two days in a row is pure magic for a reef.
A little further out, September 28th Monday looks promising with gentle offshore wind on a 5ft SSW swell (17 seconds) and solid energy (1707). A touch less certain this far out, but the signs are good.
Overall, the quality is consistent for advanced surfers, but crowd potential is there – Bommie Peak can get busy. The best of it is definitely that Saturday the 19th through to Sunday the 20th. Get on it.
Rusty.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Bommie Peak may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
