The Lowdown
G'day, Rusty here, with a look at what's coming up at Riozinho over the next couple of weeks. To be honest, it's a slow start, and we're looking at a proper dry spell before anything really gets going.
The first bit of action worth paddling out for isn't until the morning of Sunday, the 2nd of August. We've got a 3 ft easterly swell with a short period, and the great news is clean conditions with a light cross-offshore breeze. The combined energy is moderate at 120. It's not a world-beater, but after the wait, it'll feel good to get wet.
The real standout, the one that's got me buzzing, is Monday the 10th of August. The morning is looking minty. The swell jumps to 5 ft from the SSE with a solid 13-second period, which is proper groundswell. The energy is very strong (738), and the wind is light and offshore from the SW. That's a recipe for clean, lined-up waves at this break. This is the session to circle on the calendar.
We also have a couple of other moments that look promising. Tuesday the 4th of August sees a 2 ft glassy morning with a decent 12-second period, offering some clean little waves. Then on Friday the 7th of August, the morning brings a 4 ft swell with glassy conditions, and the energy is building (278). Not a standout, but a solid session.
Later on, Wednesday the 12th of August has a 6 ft swell from the NE with glassy conditions and strong energy (430), but the period is short at 7 seconds. It's a good option for the second week, but that Monday the 10th is the one to chase.
The water temperature is sitting at 66°, which is about average for the time of year, nothing to worry about.
So, get through this quiet start, and keep your eyes on Monday the 10th of August. That's the one.
Rusty.

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