The Lowdown

Rusty here again, giving you the same outlook in feet and Fahrenheit. Cornish Reef is in for a rough stretch. The wind is gonna be a problem for a long time, messing up what little size we get.

Water temp is about 63°, a touch warmer than normal for this time of year. The first real event is on Friday, September 4th. A big W swell hits, around 12 to 10ft, with a 12-second period and some serious energy behind it. But a strong onshore W wind at 25 km/h is gonna make it a messy, blown-out mess. This one is for experts only – too big for beginners – and honestly, it looks more interesting for kite surfing.

The rest of the first week and into the second is pretty grim. Cross-onshore winds and lumpy conditions all the way. There's a slight glimmer on Saturday the 5th with a 5ft W swell and a gentler cross-shore breeze, but it's only marginal at best. Don't plan around it.

The second week is no better. A big lull in wave height from the 10th through the 12th, with tiny surf around 1ft to 2ft. By the 13th, a 7ft W swell with an 11-second period shows up, but it's ruined by a fresh cross-onshore SW wind at 19 km/h, making it lumpy.

The best we get is right at the end, on Thursday the 17th. The swell is only 2ft from the W, with a 9-second period, but the wind finally goes light and cross-offshore from the SSE, giving us clean conditions. It's "surfable but very ordinary" – your best bet is a longboard in small, clean waves. Crowds might be around, but with waves that small, it won't matter. It's a poor run overall, flat and windy for the whole 16 days.

Rusty.

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.
