The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Cornish Reef over the next couple of weeks.
First off, I gotta be straight with you – the next 16 days are a real mixed bag, and for the most part, it’s a tough watch. The wind is the big problem here. We’ve got a lot of cross-onshore and onshore conditions, especially through the middle of the period, which is going to make things messy. The swell is around, but it’s not lining up with the wind at all.
The best chance for a paddle looks like Monday morning, August 17th. It’s not a classic, but it’s the pick of a rough bunch. We’ve got a 3ft swell from the WSW with a period of 9 seconds, pushing a combined energy of 119 (moderate wave energy). The wind is a light SSE cross-off, so the face should be clean. It’s still only a small, ordinary wave, but it’s surfable. You’ll have the place to yourself, crowd-wise, so if you’re desperate for a wetsuit tan, that’s your window.
After that, it gets ugly. The end of the second week shows a little hope. Friday morning, August 21st, looks glassy with a light WNW wind, but the swell is tiny at 2ft from the W with a 9-second period and only 85 (weak) combined energy. It’s still a surfable wave, but you’ll be hunting for a bump.
Then we get a bit of a pulse on Saturday morning, August 22nd, with a 5ft swell from the WSW, period 8 seconds, and a combined energy of 348 (moderate), but the wind is onshore and the conditions are described as marginal. It’s a gamble.
The rest of the days? Honestly, it’s a write-off. There’s a big swing of strong wind and bigger swell around the 18th and 19th, with a 10ft swell from the WNW on the 19th and a combined energy of 1597 (strong). That’s powerful, but with a near-gale cross-onshore, it’s a blown-out mess. That’s more of a kite-surfing setup than a clean paddle session.
So, the takeaway is: if you’re keen, try Monday the 17th for a clean, small wave, or hold out for the glassy, tiny waves on Friday the 21st. The water temp is about average for this time of year, so no shock there. It’s a tough outlook, but hey, forecasts can change.
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.
