The Lowdown
Gather 'round, crew. Let's talk about Corvette. This is a reef break, exposed to the south-west swell window, and it's a spot that demands a bit of respect—intermediate level, fairly consistent, but it can get crowded sometimes. The water temp is sitting at 72°, which is bang on average for this time of year, so no surprises there.
The outlook starts off a bit grim to be honest. From Thursday the 20th of August right through the weekend, we've got a mix of onshore and cross-off winds, mostly in the 18-22 mph range, with swell heights between 4 ft and 6 ft. The wave energy is moderate (values between 460 and 720), but with short 8-10 second periods, the waves will be choppy and a bit all over the place. The scores are low across the board, and the comments are either "marginal" or "poor." Not worth rushing out for.
Then we hit a bit of a lull on Monday the 24th and Tuesday the 25th morning. The swell drops to 3 ft or less, but that Tuesday morning brings a groundswell from the SSW at 5 ft with a very long 16-second period. The combined energy jumps to a strong 1125, and we get offshore winds from the east at 18 mph. That's a sweet combo—the longer period means the waves will have real shape and power, and the offshore wind will keep 'em clean. This is the first standout call. The afternoon is similar, with 5 ft SSW swell and 15-second period, energy at 1065, and offshore winds. It's a bit more size, but still manageable for the intermediate crew.
Wednesday the 26th is a bit of a step down in quality, with cross-off winds and slightly smaller swell, but still some decent energy.
Now, here's the real gem. On Thursday the 27th of August, light east-northeast winds at only 6 mph become offshore, and we've got a 4 ft SSW groundswell with a 15-second period. The energy is strong at 895, and the forecast calls for "expect very good surf conditions." The morning is the best bet, with the lightest breeze. The afternoon is solid too, with a moderate offshore breeze. This is the standout session of the whole forecast.
Friday the 28th of August morning is glassy as it gets—3 mph WSW wind, offshore, and 3 ft SSW swell at 13 seconds. The energy is moderate at 352, and conditions are called "good." A beautiful, clean morning for a longboard or a fun shape.
After that, the quality drops off again. From Saturday the 29th through the end of the month, it's mostly cross-off winds, smaller swell, and poor-to-marginal conditions. There's a brief blip on Monday the 31st with a bump in size to 6 ft, but it's a short-period SE windswell, so it won't be a favourite.
Heading into September, Tuesday the 1st has some offshore wind and a mixed bag of swell, but it's not until Wednesday the 2nd of September that we see another promising window. The morning has a 4 ft SSW groundswell at 14 seconds, offshore winds from the NE at 18 mph, and energy at 610. The afternoon gets even better with a "very good surf conditions" call, a 3 ft SSW swell, NE wind at 12 mph offshore, and energy at 558. That's a solid, clean swell.
Thursday the 3rd and Friday the 4th fade out with smaller waves and onshore winds, so the window closes.
So, the two real standouts are the Tuesday the 25th of August session with that long-period groundswell and offshore winds, and the Thursday the 27th of August morning with light offshore winds and very good conditions. Keep your eyes on those.

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.
