Alright, this is Rusty checking in with a look at your local surf outlook. The pattern over the next couple of weeks is dominated by a persistent westerly wind, which means clean, offshore conditions are pretty much off the table for a while. We're looking at a long run of so-so to poor surf, so don't get your hopes up for anything classic.
The only break on the radar is The Rock, a pretty consistent beginner-friendly reef set-up. It's exposed to swell, so it catches most things, but the wind is the problem here. For the next week and a half, the wind is stuck in the west, blowing cross-shore. This creates a nasty cross-chop on the surface, messing up what would otherwise be a decent wave.
There's a bit of a pulse around Wednesday the 9th, with a 5ft swell from the west showing up, and combined energy hitting a moderate 1859. The wave period drops to 11 seconds on that one, so it'll have some push, but the cross-shore wind will keep it bumpy.
The highlight, if you can call it that, arrives on Friday the 12th of July. The swell stays up around 5ft from the west, and the period shortens to 9 seconds. The combined energy is still moderate at 642, but the wind backs off slightly to 12 mph. Still cross-shore though, so it's a case of "marginal" at best.
After that, from the 13th of July through the end of the outlook, the swell drops and the wind stays relentless. There are a few pulses of long-period groundswell (over 20 seconds!) around the 13th and 14th, but the swell is tiny (2ft) and the wind is just ruining it. A 21-second period wave at 2ft in a cross-shore wind is more of a ripple than a ride.
Forget about paddling. With persistent moderate cross-shore winds and plenty of chop, The Rock looks far more interesting for a kite session than a surf. The water temp is just average for this time of year, so no surprises there.
Really, there's nothing in this 16-day window that I'd paddle out for. Keep your gear waxed and wait for a change in the wind.
Rusty.

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