The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks at Corvette. This is a reef setup, pretty exposed to the swell, and it’s a fairly consistent spot. The water is sitting at 72°, which is bang on average for this time of year, so no surprises there.
Right now, we’re looking at a bit of a flat spell to kick things off. The first real surf we can talk about kicks in on Tuesday the 18th of August, with a solid southerly swell mixing through. We’re looking at 8ft of swell from the S, with a period around 12 seconds. That’s a decent groundswell, but the wind is a fresh cross-off from the SE at 22 mph, which will keep it clean but a little tricky. The combined energy is strong (2998). It’s still a bit marginal on the tide, but for the more experienced crew, there’ll be waves.
Wednesday the 19th sees a similar pattern, with the swell dropping slightly to 6ft from the SSE, period 11 seconds. Still a fresh cross-off breeze, so the face will be clean. Energy is still strong (1590). Thursday the 20th keeps the 6ft swell, but the period drops to 9 seconds, so it’s a bit more local and less powerful. The wind stays cross-off, but the energy drops into the moderate range (1124).
Friday the 21st sees the swell holding around 6ft from the SE, but the period drops to 8 seconds. That’s short period, sloppy stuff. The energy is weak to moderate (683). By Saturday the 22nd and Sunday the 23rd, the swell is still there, but the scores are poor. The wind is howling, the period is short, and the energy is weak. It’s not looking good at all.
Now, there’s a bit of a gap here. The surf quality is poor until the 24th, but we get a small window Monday morning the 24th. The swell is 5ft from the ESE, period 8 seconds, but the wind goes offshore at 19 mph. That’s a clean look, but the energy is weak (371). It’s a marginal call, but the offshore wind is a major positive.
Then things get interesting. On Tuesday the 25th, we get a proper long-period groundswell from the SSW. The swell is 5ft, but the period is 16 seconds. That’s very long period. The wind is offshore again in the morning at 19 mph. The energy jumps back to strong (1221). This is a standout window. The long period and offshore wind will make for some clean, well-shaped waves, but that long period at a reef? It’ll be lined up and powerful. Best for the experienced surfer.
The swell holds through Wednesday the 26th and Thursday the 27th, with periods between 13 and 15 seconds, but the swell drops to 3ft. The wind is light on Thursday the 27th, with a 3 mph cross-off, so it’s glassy. The energy is weak (384), but it’s clean.
Friday the 28th is glassy in the morning, with a 2ft SSW swell at 11 seconds. The energy is very weak (160). It’s ordinary, but at least it’s clean.
Now, here’s the real headline. Look at Monday the 31st of August. We’ve got a monster SSW swell rolling in. The morning sees 7ft at 18 seconds, with a moderate cross-shore breeze. The energy is very strong (5093). By the afternoon, it’s pumping 13ft at 17 seconds, with a fresh cross-shore breeze. The energy is a massive 9006. This is a serious, serious groundswell. Over 8ft, it’s experts only. That’s a solid, powerful, heavy wave. The cross-shore wind will add some chop, but for the big wave chargers, this is the big one.
Tuesday the 1st of September carries that energy through, with 12ft from the SSW at 16 seconds in the morning, energy at 5609. The wind is cross-off, so it’s clean. Still experts only.
The swell finally drops off into Wednesday and Thursday the 2nd and 3rd.
So, the standout? No question, it’s the 31st of August and the 1st of September. That’s the big, long-period groundswell. It’s a week and a half away, so we’ll keep an eye on it, but it looks promising. For the rest, the Tuesday the 25th with the offshore and long period is a good, clean option.
Stay safe out there.

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