The Lowdown
Alright, Rusty here, let’s talk about what’s cooking at Bommie Peak.
We’ve got a solid run of swell on the way, but it’s not all clean. The real standout is Monday morning, August 3rd. We’re looking at a 5ft SSW groundswell, with a period of 15 seconds, pushing into the reef. The wind is glassy, absolutely dead calm, which is a rare treat. The water is sitting at 85°, which is about average for this time of year, so no surprises there. The energy is strong, and for an advanced crew, this is going to be absolutely pristine. The only catch is it’s an exposed reef, so you need to know what you’re doing.
After Monday morning, the wind gets messy. Tuesday through to Saturday the 8th are all cross-shore or cross-onshore, with moderate to fresh breezes, turning the lineup into a choppy, lumpy mess. The swell hangs in there, but it’s not worth paddling out for. The energy stays high, but the wind just ruins it.
Then, we get a second window. Sunday morning, August 9th, the wind swings offshore from the SE, light at 15 km/h, and the swell is still a solid 7ft from the SSW with a 15-second period. The reef will be handling that long period energy well, but it’s going to be a powerful, heavy wave. The energy is strong, and it’s clean. This is the other standout for the advanced crew.
From there, the outlook stays pretty consistent with clean conditions, mostly cross-offshore winds, through the middle of August. The swell size bounces between 4ft and 8ft, and the energy is strong to very strong. Keep in mind, a long period swell like this can make the reef a bit more critical, but it’s a point/reef setup, so it should hold well.
The last real highlight is Friday afternoon, August 14th. A 7ft S swell with a 16-second period, light offshore winds, and clean conditions. The energy is very strong. This is another one for the experienced lot.
Don’t bother with the afternoons early on, they’re a write-off. The first week is a battle of patience, but the mornings on the 3rd and 9th, and the afternoon of the 14th, are the ones to circle.
Rusty out.

Information about the Bommie Peak Surf forecast
The above surf forecast table for Bommie Peak provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Bommie Peak can be found by selecting the local surf guide option on the grey menu. Our Bommie Peak surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Bommie Peak) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
