The Lowdown
Alright, let’s get into it. The next couple of weeks are gonna test your patience if you’re chasing waves at Trevone Bay. We’re looking at a long stretch of small, messy, and wind-blown conditions, with only a couple of brief windows where it cleans up enough to be worth a paddle.
Right off the bat, for the 9th and 10th, there’s just nothing doing. We’re talking ankle-biters under 1ft with onshore junk. The energy is weak, with combined energy readings in the teens and twenties. You’d be better off finding a rock pool.
Things pick up a touch on the morning of Monday the 11th. There’s still not much size, around 1ft, but a light offshore breeze from the SE cleans things up. The combined energy is still weak at 29, so it’s a longboard-only kind of morning. The afternoon drops even further, so don’t plan your day around it.
Now, here’s the one real highlight in this whole stretch: Wednesday the 12th. The morning is nothing special, but the afternoon is where it’s at. We get a glassy, clean 3ft of west swell with a period of 9 seconds. The combined energy jumps to 139, which is at least in the moderate range. It’s not big, but it’s clean, and that’s gold. This is the best call for a beginner looking for some gentle, pushy waves without any hassle. The swell direction is from the west, right in the pocket for Trevone Bay’s WNW exposure.
But it’s a short-lived window. From Thursday the 13th through the weekend, the wind swings onshore and chops everything up. The swell gets a little push, with some 4ft readings, but the wind state is consistently poor. The energy gets up to 274 on Thursday morning, but it’s all for nothing with that bump on it. Not worth a look.
The following week is a grind. There are a few days with some energy—like the 19th and 20th with 3-4ft swells and periods up to 10 seconds—but the wind is either cross-shore or cross-onshore, keeping it lumpy and messy. The 21st has a clean reading but the wind is a strong cross-off at 19 mph, which is going to be a battle just to get out.
The only other moment of promise is on the morning of Saturday the 23rd. We get another glassy window, with a clean 3ft of WNW swell. The energy is a moderate 140. It’s similar to the 12th, but slightly less clean with a bit more size. It’s a decent call, but it comes after a long run of nothing, so keep your expectations in check.
To be honest, Trevone Bay is a pretty consistent break, but this forecast is a real dud. The water temperature is about average for this time of year, so no surprises there. The main thing is to be patient and wait for those two windows of light, offshore wind. If you’re set on surfing, the 12th of August is the standout, with the 23rd as a backup. Everything else is a write-off.

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.
