The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the table for the next couple of weeks.
We’ve got a pretty quiet stretch ahead, to be honest. The first few days are looking flat and uninspiring, with a real lack of energy. The swell that does show up is small and weak, and the wind is mostly onshore, which is a real shame. The water is sitting at a warm 73°, which is much warmer than normal for this time of year, so you won’t need a thick wetsuit, but you will need patience.
The best bet on offer, and it’s a bit of a stretch, is Big Rock (reef). It’s an advanced spot and fairly consistent, but don’t expect perfection. The standout moment is likely to be Thursday, 24 July afternoon. The swell bumps up to 4ft out of the SSW, with a period of 13 seconds, and the wind is a gentle cross-shore. That’s about as clean as it’s going to get in this window. The combined swell energy is moderate (742). It’s not a world-beater, but it’s the best of a quiet bunch. For the advanced crew, there’s a pulse on Friday, 31 July with a 6ft SSW swell, but the wind is cross-on, so it’ll be a bit lumpy. The energy is stronger there (1106), so it’s one for the more experienced surfers only.
Honestly, for the first week, it’s mostly marginal. The groundswell that shows up from the 24th has a long period (21-24 seconds) which is great for the reef setup here, but the size is small. The long period means the sets will be well-spaced, making the paddle out easier, but you’ll be hunting for waves. The crowds are "often" here, so expect company.
The second week (from 28 July onward) doesn’t offer much to get excited about. The swell stays around 3ft to 4ft, and the wind is mostly onshore or cross-onshore. Nothing really stands out as a must-surf session. The energy dips and the quality just isn’t there.
So, to wrap it up: if you’re an advanced surfer and you’re desperate, aim for 24 July afternoon at Big Rock. Otherwise, it’s a good time to clean your gear and wait for the next forecast.
Rusty.

Information about the Big Rock Surf forecast
The above surf forecast table for Big Rock provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Big Rock can be found by selecting the local surf guide option on the grey menu. Our Big Rock 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 (Big Rock) 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 Big Rock 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.
