The Lowdown
Alright folks, Rusty here. Let’s be straight with you – Trestraou’s got a long, quiet stretch ahead. The first week and a half is basically a write-off: tiny, weak, onshore‑blown slop with next to no energy. The water’s sitting at 64.2°, which is pretty average for this time of year, so no surprises there.
Starting Monday 20 July, we’ve got a pitiful 0.7ft of WNW groundswell with a period of 11 seconds, but the wind is onshore from the NE at 15.5 mph, and the combined energy is just 27 – barely a ripple. Tuesday stays similar: 1.3ft, onshore, energy around 45, and the wind is still messing it up. Wednesday’s morning looks glassy with only 3.1 mph of onshore breeze, but the swell is still only 1.3ft at 10 seconds, so it’s flat and featureless. The whole week through to Saturday 25 July stays under 1.3ft, with the wind mostly cross‑onshore or onshore, and energy dropping as low as 14. Nothing to get

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.
