Alright, rust bucket here, Rusty, looking at the charts for the next couple of weeks. Let me tell you how it is.
The next ten days are a tough slog. From now until about July 19th, there’s almost nothing on offer. We're talking tiny 0.6ft to 2ft waves with weak energy that barely gets into double digits (topping out at 95). The water is about 61°F, which is a degree warmer than normal, so it’s not cold, but the surf is dead. Unless you need to wash the sand out of your wetsuit, don't bother.
We get a little bump around July 20th, but the wind is ugly. Monday morning sees the swell hit 5ft, with energy in the low 200s (211), but a cross-onshore wind messes it up. It gets bigger in the afternoon to 6ft, but the wind goes onshore, and it's just messy.
The one moment that really stands out is the morning of Wednesday, July 22nd. That's a serious 12ft swell from the WNW, with a period of 11 seconds. The energy is massive, reading 3114. But that size is just too much for this break, and the wind is onshore. The data says it's too big. This is for absolute experts only, and even then, it's going to be a maelstrom. You've been warned.
Cornish Reef is the only spot in the cards. It's a fairly consistent reef that is wide open to the west. For almost the entire run it’s not going to work. After that huge day on the 22nd, it drops back into the 3-5ft range with onshore winds and short period, so the quality is poor.
So there you have it. A load of flat days, then one day of terrifyingly big, messy surf. It’s a grim forecast. Keep the board in the car, but don't get your hopes up.
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.
