Alright, Rusty here again, same story but in feet and miles per hour.
Let’s be straight: Trestraou ain’t firing for the next couple of weeks. There’s surf on the charts, sure, but it’s mostly small—knee to waist high for most days—and the wind is just plain wrong. A persistent cross-onshore or onshore breeze is chopping up what little wave there is. Water temp is about 64°, which is a touch warmer than usual, but that’s the only good news.
Monday the 6th of July starts with a WNW swell around 3ft and a 9-second period. Morning is glassy with light east winds at 3 mph, combined swell energy is weak (108). It’s clean but there’s no push. By afternoon, the wind goes onshore from the NNE at 9 mph and it’s game over. That’s the whole first week: small WNW swell, period 8 to 10 seconds, and wind always cross-onshore or onshore. The afternoon of Saturday the 11th sees combined swell energy hit 166, but it’s still only 2ft with cross-onshore chop. Frustrating.
The second week gets even worse. From the 13th to the 17th of July, the swell drops to almost nothing—0.3ft to 1ft. Wind stays cross-onshore and picks up to 15 to 25 mph. Combined energy drops into single digits. For a solid five to six days, there’s nothing worth paddling for.
Then things build around the 18th of July. Saturday the 18th morning has WNW swell hitting 5ft with a short 7-second period. Combined energy jumps to 200, but it’s cross-onshore and choppy. Sunday the 19th is the standout. Swell peaks at 7ft from the WNW, with moderate cross-onshore wind from the NNW at 15 mph. Combined swell energy is a strong 608. That’s real size. Period is only 8 seconds, so it’s windswell—messy and sectiony. At 7ft, this is big surf for experts only. Crowds are possible at Trestraou.
By Monday the 20th, the swell drops to 4ft to 5ft, energy settles to 164-169. Wind goes cross-shore from the NW on Monday afternoon—better. Tuesday the 21st holds around 4ft to 5ft with gentle cross-onshore winds, energy in the 200s. Doable, but not classic.
Bottom line: the only surf worth getting excited about is the big pulse on Sunday the 19th of July. That’s your day for size and power, even if the wind ain’t perfect. Everything else is too small or blown out. For a beach like Trestraou, those bigger days with short-period swell and cross-onshore wind are messy—maybe better for a kite session.
That’s the long and short of it.
Rusty.

Information about the Trestraou Surf forecast
The above surf forecast table for Trestraou provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Trestraou can be found by selecting the local surf guide option on the grey menu. Our Trestraou 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 (Trestraou) 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 Trestraou 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.
