The Lowdown
Alright, Rusty here. Let's get into it.
First up, we've got a solid run of surf coming our way on the reef. The window opens Monday afternoon, July 27th, and it just keeps giving. The water is sitting at 85°, which is pretty much spot on for this time of year, so nothing weird there.
We kick off Monday afternoon with a clean 3ft swell from the SSE, but the real magic starts brewing from Tuesday morning. That's when we get a proper groundswell from the SW, with a 16-second period, pushing 2ft. The energy is already building (413), and the wind is offshore. It's a slow, powerful pulse, classic for a reef setup like this.
By Wednesday the 29th, the swell is up to 3ft from the SSW, still with that lovely 15-second period. The morning session will be a dream with offshore winds, and even the afternoon, with a cross-off, is looking clean. The energy is climbing (498-599), and it's getting very good.
Now, for the standout. Lock in for Thursday the 30th. The morning sees a 3ft SW swell with a 19-second period. That is a very long period groundswell, meaning serious energy and long, clean lines. The combined energy is 965, and with a gentle cross-off breeze, this reef is going to be firing. This is the pick of the early week.
Friday the 31st keeps the party going, building to 5ft from the SW by the afternoon. The period is still a meaty 16 seconds, and the energy is now over 1000 (1125). The wind is light and cross-off. This is excellent for experienced surfers.
Saturday the 1st of August, we get a glassy 5ft morning from the SSW. The wind is basically nothing. It will be perfect, but at 5ft on a reef, the crowd is likely to be there. Sunday holds similar, with a clean 5ft, and the energy stays high through to Monday the 3rd.
The next real standout is on Saturday the 8th of August. The morning shows a 8ft SSW swell with a 19-second period. The combined energy is a massive 4966. That's a lot of power. The wind is a gentle offshore from the ESE. This is for experts only. Any swell over 8ft is for experts, and this is right on the edge. The afternoon peaks at 8ft, but the wind goes cross-off, so it's still clean but potentially a bit much. Sunday the 9th holds steady at 8ft with clean offshore winds, another massive day for the experienced crew.
The last week of the forecast, from the 10th of August, the swell drops a touch but stays in the 6ft to 7ft range. The wind picks up to a moderate breeze, which will roughen things up a bit. It'll still be surfable, but the quality drops off compared to the earlier, cleaner days.
So, if you're asking me, the absolute best on offer is Thursday the 30th of July for that clean, long-period groundswell, and Saturday the 8th of August for the big, powerful, expert-only session. Don't sleep on the Saturday the 1st glassy morning either.
Rusty.

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.
