The Lowdown
Alright, folks, Rusty here. Let’s be straight with you: the next couple of weeks are looking pretty grim for a proper paddle. We’ve got a long stretch of lumpy, wind-blown conditions and not a lot of decent swell to get excited about.
We’re starting out at Portreath Beach and it’s a bit of a write-off for a while. The water is running a touch warmer than normal for this time of year, which is nice, but the surf isn’t. Through the 12th and into the weekend, we’ve got weak, short-period swells with energy readings in the low hundreds – nothing with any punch. The winds are mostly cross-onshore and that’s making it messy and choppy. The waves are there, but they’re not worth suiting up for. Honestly, for the next week or so, the only thing this surf is good for is a kite if you’ve got one.
There’s a brief glimmer of hope on Monday the 24th. A solid west swell rolls in with a moderate energy reading of 513 to 526, pushing the surf up to 6.5ft. The wind is light and offshore from the southeast, so that’s going to clean it right up. This is the standout of the whole window – it won’t be for beginners at that size, but for the intermediate crew, this is the one to circle. It’s a week out, so keep an eye on it, but it’s promising.
Beyond that, we slide back into the same pattern of onshore winds and weak, mushy waves. The energy drops right off, and it looks like we’ll end the month with more of the same – a bit of swell, but nothing organized. It’s a long, flat spell ahead, so don’t hold your breath. A blank run like this is more normal for the area when the wind gods turn against us. Forecasts can change, but right now, it’s a waiting game.

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 Portreath Beach 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.
