The Lowdown
Alright, let’s get into it.
The next couple of weeks are a proper mixed bag. We’ve got a slow and sloppy start, a wild and woolly middle stretch, and then some real hope at the end with some clean lines. You’ll need to pick your moments, but there are waves to be had.
The first real surf I’d even talk about is a long way off. It’s flat and messy between now and then, so expect a real dry spell for the next week. Don’t bother waxing up.
Things start to look a bit more interesting around Thursday the 24th. The swell fills in from the west, chest to head high at about 6ft, with a solid 11-second period pushing it. The energy is moderate (828), and with a light offshore breeze in the morning, it should be clean and lined up at Cornish Reef. This is the standout of the first week. The water temp is sitting at 61°F, which is a touch warmer than normal for this time of year, a pleasant start to the day. The wind is light and offshore, making for some clean, racable walls.
The Friday morning after that, the 25th, looks even cleaner. It’s smaller, around 4ft, but it’s glassy out of the southeast with the same westerly swell. It’ll be a playful, fun size, but not as much push as the day before. Worth a paddle, but Thursday looks like the pick.
Looking into the second week, there’s promise but definitely a "don’t book your flights yet" vibe. Around the 29th, we see a new longer-period west swell showing up. Wave heights around 5ft, but the period stretches out to a very long 14 seconds. This is proper groundswell. That long period means it’s got some serious energy behind it, and you might see some nice lines. The cross-off winds should keep it clean, and it’s looking like a promising session. Just keep in mind, it’s a while out, so treat that one with a bit of caution.
So, the long and short of it: suffer through the first week, get your best waves on the morning of the 24th, and keep an eye on that last Tuesday for a long-period pulse that could be really good. This reef can handle it.
Stay stoked.

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.
