The Lowdown
Alright, folks, Rusty here. Let's have a look at what the ocean's got in store for us over the next couple of weeks. It's a bit of a mixed bag, and I'll be straight with you – there's a lot of waiting around for the good stuff.
Right off the bat, don't get too excited. The first week is pretty much a write-off. We've got swell, sure, but it's mostly messy, lumpy, and fighting against a bunch of onshore and cross-shore wind. The water temp at Trevone is sitting at a touch warmer than normal for this time of year, a notable 66°F, which is a bit of a silver lining as we wait.
We kick off on Thursday, the 27th of August, with a tiny 1ft of west swell. It’s clean, but there's no power behind it. So small it wouldn't get you over the sandbar. Friday brings more size, but the wind is all wrong, making a mess of things. Saturday the 29th sees the swell jump up to 10ft, but with a near-gale cross-onshore, it's a washing machine out there. That's not surf, that's a survival mission. Sunday, Monday, and into Tuesday are all in the "poor" category – the swell is there, but the wind just ruins any chance of a clean face. We see a big pulse of energy mid-week, but it's just too rough to be fun.
The first real sign of life comes on Saturday the 5th of September. For the morning, we've got a clean 5ft west swell with a nice 11-second period and just a slight offshore breeze. This is looking like the first proper window. But, and this is a big but, Saturday afternoon is a different story. The swell is predicted to jump to a solid 10ft, and while the wind is light and clean, it's just too big for Trevone Bay. It’s a spot that can’t handle that kind of size, especially for a beginner-friendly beach break. This is really only for the experts if they're hell-bent, but it's a risky one.
After that, the ocean takes a breather again. The following week is a letdown, with lots of medium swell but almost constant onshore winds. A few days even have the wind coming straight onshore, which makes it completely unsurfable. There are some cleaner windows but the swell drops right off, leaving us with tiny, weak waves. The period stays around 9-10 seconds, which means the swell is there, but the wind just won't cooperate.
The best call of the whole 16-day stretch is definitely that Saturday morning on September 5th. A clean, glassy 5ft with a touch of offshore wind is about as good as it gets from what I'm seeing. The combination of clean conditions and a decent-sized, longer-period swell makes for some proper shaped waves and easy paddling. The energy is moderate, but the quality will make up for it.
It's going to be a patience game, lads. Lock in that Saturday the 5th, get your wax ready, and be on it early. There’s a lot of junk in between, but that window looks worth the wait.
Rusty, out.

Information about the Trevone Bay Surf forecast
The above surf forecast table for Trevone Bay provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Trevone Bay can be found by selecting the local surf guide option on the grey menu. Our Trevone Bay 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 (Trevone Bay) 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 Trevone Bay 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.
Trevone Bay is 4 km (2 miles) from Padstow. If you plan a holiday in North Cornwall, look for hotels and other accommodation in Padstow. Padstow has rooms for a wide range of budgets as well as car hire and transport links.
