The Lowdown
Alright, Rusty here. Let's get straight to it.
This 16-day run for Coqueiros is a tough one to swallow. From the get-go, right through Saturday the 8th, we’ve got weak, short-period waves (combined energy values between 74 and 164) and every single session is blown out by a cross-onshore or onshore breeze. It’s choppy, messy, and a total scratch-fest.
Then we hit a flat spell from Tuesday the 11th through Thursday the 13th where the combined energy drops into the 40s and 80s – barely a bump.
The only flicker of hope is way out at the tail end. On Monday the 17th of August, the afternoon shows a jump to 1.9m from the NE, with a combined energy of 296. That’s the biggest, most powerful surf of the whole period. But with that period stuck at a short 6 seconds and the wind screaming straight onshore, it’s going to be a bumpy, raw, powerful mess. That’s strictly for experts, and even then it’s not clean.
The water temp is a warm 28.1° – a touch warmer than average for the time of year.
Bottom line, every single slot here is marked as “poor surf conditions.” There’s no standout for a clean paddle session. That bigger, onshore pulse on the 17th afternoon might be more up the alley for the kite surfers looking for some juice.
It’s a quiet stretch, folks. Keep your eyes on the long-range charts, things can change fast.

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