Updates in hr min s Forecast update imminent
Alright, time to break it down in feet.
First thing: this place has been asleep. From Saturday July 4th right through Tuesday morning the 7th, Corners (reef) is offering nothing but tiny ankle-biters. 1ft and under, short period, messy wind. Not worth getting wet.
Tuesday afternoon the 7th we get a twitch – about 4-5ft SSE groundswell with a very long 17-second period. Energy’s moderate (1062), but wind’s cross-on, so it’s still only marginal.
Wednesday morning the 8th is the real wake-up. Corners sees about 10ft of SSE swell at 18 seconds – big, deep ocean energy (4969). Wind is NNE at 15 km/h, cross-off, so the reef will be clean. This is for advanced surfers only. 10ft is too big for beginners, and with that long period it’ll be thumping. Expect a crew out there; it’s often crowded.
The standout? Thursday the 9th. Morning delivers 13ft SE groundswell with offshore NE wind at 18 mph – that’s clean, groomed, and powerful. Energy is massive (10002). Afternoon bumps to 14-15ft SSE, still offshore, energy at 13361. This is big-reef territory, expert-only. The swell direction is spot-on for the reef’s optimum SW.
Friday the 10th is off the charts – morning finds 31ft of SSE, 18-second period, energy at 91951. That’s way too big for any paddle-in session. Saturday the 11th is still monstrous with 21ft in the morning, easing to 16ft by afternoon.
Sunday the 12th drops to 10ft then 8ft, but now the wind goes cross, so quality drops. Monday the 13th brings cleaner conditions with 6ft to 5ft SSE swell, cross-off wind, but period drops to 8 seconds. Energy’s down to 614. It’s okay, not firing.
From Tuesday the 14th on, it’s a slow fade. 4ft, then 2ft, then tiny 1-2 foot leftovers, offshore winds keeping them pretty but weak. By the weekend of the 19th, it’s nearly flat again.
Water temp is 82°F, about 2°F cooler than average – a touch below normal for July, but still warm.
Best session: Thursday the 9th at Corners. Big, clean, offshore, and heavy. If you’ve got the skills, that’s your window.

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.
