The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer.
Right off the bat, the next week and a half is a bit of a heartbreaker. We’re looking at a long stretch of pretty ordinary, small, and often messy conditions. The surf is there, but it’s not really calling you out of bed. The first real standout isn’t for a while, so patience is the name of the game.
Starting with the early days, the swell is small and the wind is a problem. Sunday the 9th sees a weak 3 ft west-northwest swell with a moderate cross-onshore wind, making for choppy and unpleasant conditions. The combined energy is weak to moderate (154-263). Monday the 10th has a bit of hope with a glassy afternoon and a tiny 2 ft west swell, but the energy is very low (58). It’s clean, but barely surfable. Tuesday the 11th drops right off.
The whole run from Wednesday the 12th through to Saturday the 22nd is a mixed bag of onshore or cross-offshore winds and small, weak swell. The energy stays mostly under 300, with a few sessions getting a bit more, like the morning of Thursday the 13th (290) but the wind is cross-on. There’s a morning on Friday the 21st that’s clean with a 4 ft west swell (252 energy), but it’s still just marginal.
Now, here’s the real standout. Keep your eyes on the morning of Saturday the 22nd of August. That’s the one. The swell pushes up to 5 ft from the west, with a period of 9 seconds. The wind goes light and cross-offshore from the east-northeast, cleaning it right up. The combined energy is a solid moderate 323. This is the best window in the whole 16-day forecast for Cornish Reef. It’ll be a proper reef break with some shape. Expect crowds, as it’s a spot that can get busy.
The water temperature is running about average for this time of year.
The afternoon of the 22nd gets messy again with a cross-on breeze, and the days following that are a mix of moderate cross-shore winds and dropping swell.
So, the big one to circle is Saturday the 22nd of August for the morning session. Everything else before that is a gamble on a very small, clean window.
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.
