The Lowdown
Alright folks, Rusty here. Let's chew the fat on what’s heading our way.
Alright, we’ve got a pretty solid run of surf on the cards, but it’s a bit of a slow burner. The real fireworks are a good way off, so we’ll need to be patient.
The first real standout is Grinders. This spot is exposed and picks up a long-period SW groundswell, so it’s all about quality.
Looking at Monday the 17th, we’re straight into it. The morning looks mint – clean, with a light cross-off breeze, and a solid 3ft SW swell with a super long 16-second period. The water is 56°, which is pretty normal for this time of year. The energy is moderate (554), but that long period means proper shaped waves with long lulls between sets. It’s an advanced wave for sure, and it can get crowded sometimes, but the conditions are set to be excellent.
The rest of that first week is a bit of a tease. The swell sticks around but the wind gets a bit fickle, mostly cross-off or onshore-ish, keeping the quality just ‘marginal’. There’s a bump on Friday the 22nd morning with a 5ft swell, but it’s a bit of a mixed bag.
Now, for the true standouts, we’re looking at the second week. Saturday the 29th is a big one. The morning session at Grinders is looking excellent for experienced surfers. We’ve got a solid 7ft SSW swell here, a light cross-off breeze, and the wave energy is strong (1231). The period is a short 8 seconds though, so it won't have that long-period power, but it’ll be punchy and fun. It might be a bit much for beginners, that’s for sure.
Then, to wrap it up on Monday the 31st, another cracker. The morning has a 7ft SW groundswell pumping in with 17-second periods. The energy is very strong (2230) and the wind is light and offshore. This is expert territory again, and the conditions are described as excellent. The long period will make it break straight at the beach, but for a reef like Grinders, it’ll be an awesome sight. The afternoon holds up nicely with offshore winds and a 6ft swell.
So, the pick of the weeks is undeniably the 29th of August morning and the 31st of August morning. Get excited, but don't drop in.

Information about the Grinders Surf forecast
The above surf forecast table for Grinders provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Grinders can be found by selecting the local surf guide option on the grey menu. Our Grinders 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 (Grinders) 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 Grinders 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.
Grinders is 34 km (21 miles) from the city of Geelong. If you plan a holiday in Torquay, look for hotels and other accommodation in Geelong. Geelong has rooms for a wide range of budgets as well as car hire and transport links.
