The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s coming up for Cornish Reef. It’s a bit of a slow burn for the next week and a half, but there’s a real glimmer of hope at the tail end of the forecast if you’ve got the patience.
We’re kicking off with a pretty flat spell. From Wednesday the 22nd right through to the end of July, the waves are tiny and the wind is mostly messy. You’ll see a few pulses of small swell, but the wind is either cross-on or onshore, and the water is just a bit of a mess. The combined energy is weak, sitting around 18 to 18 for the first few days, and while it builds a bit, it’s all poor surf conditions. Don’t bother getting too excited just yet.
Then from the 30th of July into early August, the swell starts to pick up a little, but the wind is still a problem. The water temperature is a touch warmer than normal at 62°F, which is a bit unusual for this time of year, but it won’t make up for the choppy, lumpy surf. The energy climbs, but it’s still a tough call.
The real standout for this entire forecast window is Tuesday the 4th of August. We’ve got a clean, offshore wind from the ESE at 6 mph, which is a dream for a reef setup. The swell is 6 ft from the W, with a combined energy of 418 (moderate wave energy). That’s a proper groundswell for the experts, and the light offshore will make it glassy. This is the best on offer, and it’s a genuine chance for a score. The next morning, Wednesday the 5th, also looks clean with a 6 ft swell from the W and cross-off winds, though the energy is a bit higher at 562 (strong wave energy). That’s a fine session too, but the Tuesday afternoon is the pick.
Before that, Saturday the 2nd of August sees a small, messy pulse, and Monday the 3rd has a clean morning but the swell is small and weak. The good stuff is definitely the 4th and 5th.
So, get your diary out for the 4th of August. That’s your window. Long-range, but promising. Don’t hold your breath for the first week, just get ready for that Tuesday.
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.
