The Lowdown
G'day, Rusty here, and I've gotta be straight with you—this outlook for Guarau is a bit of a slow burner. The first week is looking pretty flat and ordinary, but there's a decent pulse of energy building for the second week that could make it worth hanging in there.
The water temp is sitting at 68°F, which is a touch warmer than normal for this time of year, so you won't need a thick wetsuit.
We're kicking off on Saturday morning, 1 August, with tiny 3 ft surf from the ESE at 6 seconds. The combined energy is weak (123) and honestly, it's just surfable but very ordinary. The glassy conditions with no wind are a nice start, but the swell is too small and short-period to get excited about. That afternoon, the wind swings onshore and the waves get a bit messier.
Sunday 2 August and Monday 3 August are more of the same—small, weak swell, mostly glassy mornings but nothing with any punch. Tuesday 4 August sees a drop to 1 ft from the SSE, but the period jumps to 13 seconds, which is a long-period groundswell. The energy is still weak (77), and the waves are tiny, so it's not really doing much for us.
Wednesday 5 August morning has a little more shape with 2 ft from the S at 11 seconds, and a clean cross-off wind. The combined energy is moderate (152), but it's still small. The rest of the week stays frustratingly small, with glassy mornings but waves under 2 ft. The energy is weak, rarely breaking 100.
On Saturday 8 August morning, we finally see a bit more life: 3 ft from the SSE at 9 seconds, with a glassy calm. The combined energy is moderate (161), but it's still on the small side. The afternoon is similar.
Now, Sunday 9 August is where things start to get interesting. The morning brings a solid 8 ft swell from the S at 10 seconds, with a clean cross-off wind from the NNW at 9 mph. The combined energy jumps to 1811—that's strong to very strong wave energy. This is a big swell, too big for beginners, and it's one for the experienced crew. The afternoon cleans up even more with a 5 ft swell from the SSE at 11 seconds, offshore wind, and the comment says "expect very good surf conditions." This is a standout.
But then Monday 10 August gets messy with onshore wind and light rain, dropping the quality.
Tuesday 11 August afternoon is another highlight. We've got a 5 ft swell from the SSE at a very long 14 seconds, with glassy calm conditions. The combined energy is 1050 (strong) and the comment says "excellent surf conditions for experienced surfers." That long-period groundswell will be best at a point or reef, but at Guarau (a river mouth), it might break a bit straight. Still, the potential is there for some quality waves.
The rest of the second week is a mixed bag. Wednesday 12 August has 5 ft from the SSE at 13 seconds, but with cross-shore winds and only moderate energy (610). Thursday 13 August afternoon sees 3 ft from the SSE at 11 seconds, with a clean cross-off wind and moderate energy (200). Friday 14 August is small again.
Then we get another promising window: Saturday 15 August morning. A 7 ft swell from the S at 8 seconds, with glassy calm winds. The combined energy is 993 (moderate to strong). That short period means it'll be a bit weaker on the face, but the glassy conditions make it clean. The afternoon is 6 ft from the S at 9 seconds, still glassy.
Sunday 16 August morning is the final standout. A 6 ft swell from the SSE at 12 seconds, with glassy calm winds. The combined energy is 1136 (strong) and the comment says "excellent surf conditions for experienced surfers." The afternoon gets a bit choppy with onshore winds, but the morning session looks like a ripper.
So, the best of the bunch is Sunday 9 August afternoon and Tuesday 11 August afternoon, with Saturday 15 August and Sunday 16 August mornings also worth a look. The first week is a write-off, but the second week has some real potential.
Rusty.

Information about the Guarau Surf forecast
The above surf forecast table for Guarau provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Guarau can be found by selecting the local surf guide option on the grey menu. Our Guarau 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 (Guarau) 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 Guarau 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.
Guarau is 6 km (4 miles) from the city of Peruibe. If you plan a holiday in São Paulo, look for hotels and other accommodation in Peruibe. Peruibe has rooms for a wide range of budgets as well as car hire and transport links.
