The Lowdown
G'day, I'm Rusty, and I've got the lowdown on the next few weeks for your local waves. Honestly, looking at the whole picture for Cornish Reef, it's a pretty grim stretch ahead. We're staring down the barrel of a long, quiet spell with barely a wave worth paddling for.
For the first week, right through the start of August, it's a write-off. The swell is tiny, often under 2 feet, with a weak combined energy in the teens and twenties, and the wind is almost always on it or cross-on. You'll see a bit of a spike on Wednesday the 5th when the swell jumps to 8 feet, but that's all from a short-period, onshore mess with a strong breeze, so the surf quality is poor. That's a day for the kite surfers, not us.
The only glimmer in this whole forecast comes on Sunday the 9th of August. The morning is looking like a tiny window of opportunity. The swell is only 3 feet from the west, combined energy of 133 (moderate), but the wind is glassy – dead calm. That will make the reef look clean and inviting. It's the only time in the 16 days we see that word "glass". The waves won't be world-class, but for a surf, it's the standout. Remember, Cornish Reef is a fairly consistent spot that's exposed to the west, so it's built for this kind of direction. Be aware it can get a crowd sometimes, so you might not be alone out there.
After that Sunday morning, it's back to the doldrums. From Monday the 10th right through to the end of the window on the 18th, the swell is tiny, often under 2 feet, with combined energy mostly in the single digits. The wind is a mixed bag of onshore and cross-off, but with no size, it's just not worth the effort. It's a blank run of surf that's pretty normal for this area when the charts go quiet.
So, if you're keen, circle Sunday the 9th of August on the calendar. Be there for the morning glass-off. It's not a classic, but it's the only show in town.

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