The Lowdown
Alright folks, Rusty here. Let’s be straight with you – the next 16 days at Corners are a total write‑off. I’ve been staring at the charts and there’s not a single session worth paddling out for. This reef break is usually fairly consistent and it’s a bummer, but sometimes the ocean just goes quiet. The water’s a bit colder than normal for this time of year, sitting at 81.3°F with a -3.1°F anomaly, so you’ll feel that extra chill if you do go for a dip.
We start Saturday 18 July with a weak, onshore SW wind and a tiny 2.6 ft swell from the SW, period a paltry 7 seconds – combined energy just 110 (moderate but messy). That sets the tone: the whole first week stays small, mostly 1.0 ft to 3.0 ft, with onshore or cross‑onshore winds from the SW or WSW. The only halfway decent wind comes Thursday 23 July morning when it goes glassy, then Friday 24 July through Sunday 26 July we get light offshore breezes from the NE/ENE, but the swell is only 1.0 ft with periods 9–11 seconds – hardly enough to wrap into the reef. Energy readings are pitiful, in the teens to low 20s. So, clean but tiny – not worth the drive.
Into the second week, Monday 27 July morning brings a spike: a 3.0 ft SW groundswell with a 14‑second period and energy jumping to 268 (moderate‑strong). Wind is cross‑off from the NNE at 15 mph, which should keep it clean, but the wave comment still says “poor surf conditions”. That long period will likely make the reef line up, but the swell height is marginal and the wind, though cross‑off, isn’t fully offshore. Then Tuesday 28 July the wind strengthens to a strong breeze (28 mph), and the swell drops back to 1.3

Information about the Corners Surf forecast
The above surf forecast table for Corners provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Corners can be found by selecting the local surf guide option on the grey menu. Our Corners 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 (Corners) 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 Corners 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.
