The Lowdown
Alright, surfers, Rusty here. Let’s get real about the next couple of weeks. I’ve got to be straight with you: Trevone Bay is looking at a grim stretch of small, messy, and onshore slop. There’s a long, painful gap of days with no surf worth paddling out for, so don’t rush to wax your board.
From now through the 20th of August, it’s a total write-off. We’re talking about day after day of poor surf conditions: cross-onshore winds, choppy bumpy waves, and heights that barely crawl to 5 ft, but even that is a bumpy, short-period mess (combined energy 349) that’s better suited for kites than paddle surfing. The water is much warmer than normal at 67°F with a 5°F anomaly, which is notable, but it doesn’t help the waves. The 20th afternoon shows a small window of 4 ft swell from the WNW with a 9-second period on lighter winds, but the forecast still calls it poor surf, so I’m not getting excited.
The first real chance of a surfable wave comes on the morning of Friday, the 21st of August. It’s not a standout, but it’s the best we’ve got. We’ll see a 3 ft groundswell from the west at 8 seconds, with combined energy 158, and the wind goes glassy — that’s a major plus, making it clean. The swell is small, but for a beginner-friendly break like Trevone Bay, it might be a fun little session. After that, it’s back to the grind with onshore winds and smaller waves.
The following week, from the 22nd through the 29th, is a flat, choppy, or windy wasteland. There’s a brief moment on the morning of the 28th of August with a 2 ft west swell and light offshore winds from the southeast, giving clean 2 ft waves and a score of 1 — surfable but very ordinary. The afternoon of the 28th offers glassy conditions again, but the swell is tiny. For the 29th, we get a 3 ft west swell with a 9-second period and cross-offshore winds, which keeps the face clean, but the combined energy is 129 and the conditions are still rated poor. Honestly, the whole run is a flat spell.
The water temperature anomaly isn’t provided for later sessions, but the first mention of break Trevone Bay already showed it being much warmer than normal. The break is fairly consistent, but the swell just isn’t there. Given the long gaps and poor quality, this is a time to leave the board in the shed and check back next week. Forecasts can change, but right now, there’s nothing to get hyped about.

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.
