The Lowdown

Alright folks, Rusty here. Gonna give you the lowdown for the local stretch.

Right off the bat, we’ve got a bit of a slow start. The first real chance to get wet is on Tuesday, the 28th of July. It’s not much to write home about, but it’s something. The swell is a small 2ft from the south with a nice long 12-second period, which is that proper groundswell energy. The water temp is sitting at 66° which is pretty much dead average for this time of year, so no surprises there. The wind is glassy, which is a major positive, meaning the surface will be smooth. But the wave energy is weak (188), so you’re looking at small, slow rollers. It’s surfable, but it’s very ordinary.

Wednesday the 29th is a bit of a mixed bag. The morning session looks similar to Tuesday with glassy 2ft south swell, but the energy is slightly better (209). The afternoon, however, gets blown out with a solid 12 mph southerly cross-offshore wind, making it a write-off.

Thursday the 30th is a bit cleaner in the morning with a light offshore wind from the SW, but the swell drops a little and the period shortens up to 9 seconds. The energy is also weak (132). The wind swings onshore in the afternoon, so that’s a no-go.

Friday the 31st is a total mess. Strong onshore winds from the NNE at 15 to 19 mph are going to ruin what little swell there is. Don’t bother.

The first weekend of August is looking poor. Saturday the 1st has a bump in swell height to 6ft, but it’s coming from the NE with a short, weak 7-second period. The wind is a strong, choppy cross-onshore, making it a complete washout. This is more of a kite-surfing setup than a paddling one. Sunday the 2nd offers a bit of relief with an offshore wind and a smaller 4ft swell, but it’s still short-period and weak.

The next week is a bit of a waiting game. There are a few surfable windows, but nothing that screams “go.” Monday the 3rd and Tuesday the 4th are in the bin due to onshore winds. The energy jumps up on Tuesday though (505), but the onshore wind kills it.

Things start to look up on Wednesday the 5th. The morning is absolutely glassy with a 3ft swell from the SSE. The energy is moderate (239). It’s a small, clean day. The afternoon stays clean with a cross-offshore wind.

Thursday the 6th is a write-off for the morning, but the afternoon is a real highlight. The wind goes glassy, the swell is 2ft from the south with a nice 12-second period, and the energy is moderate (285). This is a good, clean little window.

Now, here’s where we get a proper standout. Friday the 7th of August. The morning is a gem. Glassy conditions, a 5ft swell from the NE. The energy is strong (298). This is going to be a fun, punchy morning on the Praia do Porto beach/jetty setup. It’s a standout because the conditions are clean and the swell has some size. The afternoon gets a bit messy with a cross-shore wind.

The real stunner of the entire forecast period is Saturday the 8th of August. The afternoon session is looking world-class. A solid 5ft south swell with a moderate 9-second period, but the energy is huge (888). The wind is a strong offshore breeze from the SSW creating clean, hollow waves. This is the best on offer.

Sunday the 9th carries the momentum. The morning is a beauty with a 4ft south swell, a very long 13-second period, and a light offshore wind. The energy is very strong (796). The waves will be powerful and well-shaped on this point/reef setup. The afternoon is a bit more marginal.

The following week keeps the good vibes rolling. Monday the 10th is clean and consistent. The real hidden gem is Tuesday the 11th of August. The morning is a dream. Absolutely dead calm, zero wind, glassy as a mirror. The swell is a solid 6ft from the SSE with a short 8-second period. The energy is massive (781). The wind dies completely, so expect clean, powerful sets. This is a morning for experts only, as that 6ft is pushing it for beginners. The afternoon gets blown out by a strong onshore wind.

After that, Wednesday the 12th and Thursday the 13th look like a return to onshore slop, so get your sessions in on the weekend and early next week. The long-range outlook is promising but less certain.

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.

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.
