The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s shaping up for Cornish Reef over the next couple of weeks.
Overall, it’s a bit of a flat, frustrating stretch. The reef is exposed to the west and will pick up anything that’s out there, but the wind is all over the place and the waves are tiny for days on end. There’s a long gap with nothing really worth paddling out for, so don’t hold your breath early on.
The first real chance to get wet comes around Monday, August 10th. The morning shows a clean session with a light cross-offshore breeze from the southeast. The swell is only 3ft from the west, with a period of 8 seconds and combined swell energy of 82 (weak). It’s not pumping, but it’s surfable and the reef will clean it up. Not a standout, but it’s the first glimmer.
We then hit a big dry patch. From Tuesday, August 11th, through to Saturday, August 16th, the surf is either tiny, choppy, or blown out. The wind is mostly onshore or cross-onshore, and the swell rarely gets above 3ft. The combined energy is weak to moderate, but the conditions are just poor. Honestly, it’s a write-off.
Later in the second week, on Wednesday, August 19th, the swell jumps up to 6ft from the west, with a period of 10 seconds and combined energy of 549 (strong). That’s a proper bump. But the wind is a fresh cross-onshore from the south-southwest at 22 mph, making it lumpy and messy. It’s a powerful swell, but the conditions are poor. Experts only, and even then it’s a battle.
The best bet? The Monday morning (August 10th) is the only window where things line up for a clean, if small, session. The later swell on the 19th is bigger but ugly. No true standout here.
Stay patient, keep an eye on the charts, and don’t force it.
Rusty.

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.
