The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Cornish Reef over the next couple of weeks.
Right off the bat, I gotta be straight with you – the next week or so is a bit of a write-off. We’ve got a lumpy, wind-affected mess on the cards. The swell is there, but it’s coming in with a strong onshore or cross-onshore breeze, so the surface is gonna be choppy and poor. The combined swell energy is moderate to strong on the 26th of July, hitting 862, but it’s all for nothing with that wind. You’ll be battling a “fresh cross-onshore and lumpy” mess. It’s not the kind of day you paddle out for a trim; it’s the kind of day you watch the whitecaps from the car park.
We do start to see a glimmer of hope as we head towards the end of July and into the first week of August. The wind swings around to the north-east and north-north-east, giving us some clean, cross-offshore conditions. The problem is, the swell gets tiny. On the 31st of July, we’ve got a tiny 2 ft north-west swell, but it’s clean. The energy is weak at 80. It’s surfable, but just barely. You’ll be on the log, for sure.
The real standout, the one to circle on the calendar, is the 4th of August, Tuesday morning. The wind is from the north-east, gentle and clean, and the swell is a long-period groundswell from the west at 2 ft but with a period of 11 seconds. That longer period means the wave energy is a bit more focused, and the combined energy jumps to 166. It’s a small day, but it’ll be clean and have a bit more push than the size suggests. The crowd factor is “sometimes,” so you might have a few friends out, but it’ll be worth it for the clean lines.
Later, on the 5th of August, Wednesday morning, the swell size jumps up to 8 ft from the west, with a strong combined energy of 1047. That’s a lot of water moving. But the wind is a fresh cross-onshore, making it lumpy. For all but the experts, that’s a pass. The wave quality won’t be there.
Looking further ahead, the 8th of August, Saturday morning, is also worth a mention. The wind is glassy, which is a rare treat, and it’s a clean 2 ft west swell with a period of 9 seconds. The combined energy is weak at 79, so it’s a morning for the mini-mal or the longboard, but the glassy conditions will make it feel like a million bucks.
So, to sum it up: the first week is a bust. The best bet is the 4th of August morning for a clean, small but decent session, or the 8th of August morning for the glassy conditions. The bigger swell on the 5th is a no-go for general surfing due to the onshore wind.
Stay patient, and keep an eye on the sky.
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.
