The Lowdown

Alright folks, Rusty here, looking at what's on the menu for Praia do Porto over the next couple of weeks.

We've got a solid run of surf coming up, with a few standout sessions that are going to be well worth the paddle out. The first real action kicks off this Sunday, the 9th of August, and the energy is legit from the get-go. The water is sitting at 67°F, which is pretty much spot on for this time of year, so no surprises there.

Sunday morning starts with a 7ft south swell, but it's a bit short-period at 8 seconds, so it won't have the real grunt. The wind is howling from the SSW at 15 mph, which is offshore for this spot, so it'll be clean. The combined energy is solid at 1157 (moderate), making it a decent warm-up, but not the best of the window.

The real gem is going to be Tuesday, the 11th of August. We've got a 7ft south swell, but this time the period is a long 12 seconds, bringing proper groundswell energy. The morning is calling for glassy conditions, dead calm with a 3 mph offshore breeze from the SW. That's a recipe for perfection. The combined energy is pumping at 1521 (strong). This is the one to circle. For experienced surfers, this is going to be firing. The crowd factor is "sometimes" here, so expect a few others with the same idea.

Monday the 10th is also a great day, with a 8ft south swell and a 12-second period. The wind is a gentle offshore from the WSW at 9 mph, keeping it clean. The energy is even higher at 2707 (strong). This is a proper session, just a notch below the glassy Tuesday morning.

After Tuesday, the quality drops a bit. Wednesday and Thursday see the swell drop to 6ft and the wind turns more onshore, making it less ideal. There's a few windows of glassy conditions on Friday the 14th and Saturday the 15th, with smaller 4ft to 5ft swells. These are good for a beginner-plus surfer, clean and fun, but not the heavy hitters.

There's a rough patch from Sunday the 16th through Wednesday the 19th, where onshore winds and poor conditions make it a write-off. The swell is there, but the wind is trashing it. Then things start to look up again on Tuesday the 18th with a 7ft ENE swell and a clean cross-off breeze from the south. The energy jumps back to 1423 (strong), and it's a good option for experienced surfers, but the wind is a bit more tricky.

From the 20th onward, it fades. The last week shows small, weak swells with poor winds. The 23rd has a tiny 2ft south swell with a very long 12-second period, but the energy is a weak 187. It's not worth getting wet for.

Bottom line: Lock in Tuesday morning, the 11th of August, for the best chance at a glassy, powerful session. Monday the 10th is a very close second. If you're a beginner, Friday the 14th and Saturday the 15th are your best bet for clean, smaller waves.

Rusty.

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. If you surf the same spot (Praia do Porto) 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 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.
