The Lowdown
G’day, Rusty here, and I’ve been staring at the charts for our stretch of coast. To be honest, the next week and a half looks pretty average—a lot of small, messy, or onshore slop to wade through. But there is a real window of hope if you’re willing to wait. The standout is going to be that Tuesday, August 4th, where everything lines up for a proper session. Before that, you’ll be battling small, ordinary waves or cross-onshore crud. Let’s get into it.
We’re looking at Praia do Porto (beach/jetty). The water temp is sitting at 65°F, which is basically bang on average for this time of year, so no surprises there.
The next few days are a bit of a write-off. Sunday the 26th has a tiny 3ft southerly swell, but it’s weak (combined energy of 312) and the wind is from the NE, onshore, making for poor conditions. Monday the 27th morning goes glassy with a 2ft S swell (12-second period, 214 energy), and you’ll get surfable but very ordinary little waves. That’s the best we’ve got for a while, but it’s nothing to write home about. Tuesday the 28th picks up to 4ft from the NE, but the period is a short 6 seconds, and the morning is cross-onshore, the afternoon is cleaner but still average. Wednesday the 29th morning is glassy on a tiny 2ft S swell – still just ordinary.
We’ve got a long gap of very weak, small days with poor wind through to the end of July and the start of August. Thursday the 30th and Friday the 31st are mostly onshore and puny. Saturday August 1st sees a 5ft NE swell, but it’s short-period (6-7 seconds) and hammered by a fresh cross-onshore wind – that’s more of a kitesurfing setup than a paddle session. Sunday the 2nd is glassy but tiny at 3ft from the ENE, just surfable.
Now, the real deal. Tuesday, August 4th is what we’ve been waiting for. The morning brings a solid 6ft swell from the SE with a 10-second period, and the combined energy jumps to 1214 – that’s proper, moderate-to-strong energy. The wind is light from the SW, offshore, and clean. Conditions are expected to be *very good*. This is the pick of the entire forecast. It’s a bit on the bigger side for beginners, but for anyone with a bit of experience, it’s going to be firing. The SE direction matches the optimum swell direction for this spot, so it’s lining up perfectly. The afternoon drops a touch to 6ft, still clean, and still very good.
Wednesday the 5th drops back into onshore junk, and Thursday the 6th has a moderate 4ft ESE swell with a clean offshore wind – good conditions, but not the standout. After that, we’re back to small, ordinary, or onshore slop through to the end of the outlook.
So, if you’re patient, hold out for that Tuesday, August 4th. It’s the only true stand-out in the whole 16-day window.

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

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 Praia do Porto 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.
