The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming down the line for Praia Cardoso.

We’re in for a bit of a slow burn over the next couple of weeks. The first few days are pretty ordinary, with messy winds and small, weak swell. There’s a gap of several days where the conditions just aren’t worth paddling out. But hold on, because there’s a real standout session on the horizon if you can wait.

Friday morning the 11th is the first chance for a surf, but it’s not much to write home about. We’ve got a small 2ft south swell with a nice long 12-second period, and it’s glassy with very light winds. The water is sitting at 61°, which is a solid 4° colder than normal for this time of year, so you’ll want a good thick wetsuit. The wave energy is weak (136). It’s surfable, but very ordinary.

Saturday the 12th is a write-off. A short-period 7ft swell shows up, but it’s getting hammered by strong cross-onshore winds, making it lumpy and choppy. Combined energy is moderate (392), but the wind ruins it. This kind of setup looks more interesting for kite surfing than paddle surfing.

Sunday morning the 13th is a bit better. The swell drops to a cleaner 4ft from the southeast, period at 8 seconds, and it’s glassy again. The wave energy is moderate (298). It’s a decent window for a beginner-friendly wave, but still nothing to get too excited about.

The following week, Monday through Wednesday, is mostly messy with onshore winds and poor quality. The swell builds a bit but the wind kills it. Another gap of poor conditions.

Then we hit Thursday morning the 17th. This is the standout. The swell is a solid 7ft from the south, period stretching out to a very long 11 seconds, with offshore winds from the north. This is clean, powerful groundswell. The combined energy is strong (1136). This is excellent surf for experienced surfers, but at 7ft it’s getting too big for beginners. The long period will make it break with a lot of punch, best handled on a point or reef setup. This is your best bet across the whole 16 days, but being a week out, it’s promising but not locked in yet.

After that, conditions fade again. Friday the 18th drops to 4ft with clean sideshore winds, but the energy drops to moderate (410). Then from Saturday the 19th, the swell completely backs off, dropping below 2ft for several days with very weak energy. There’s another gap of poor, tiny surf.

Tuesday morning the 22nd shows a spike of 6ft with a short 7-second period and glassy conditions. The combined energy is moderate (369). It’s a fair shot but the period is short, so the waves won’t have much push.

Thursday the 24th morning offers a cleaner 4ft south-east swell with light offshore winds. Combined energy is moderate (247). A decent, clean option but nothing compared to that Thursday the 17th session.

So, overall, there’s a lot of waiting. But if you’re keen, circle Thursday the 17th – that’s the one to aim for.

Rusty.

Information about the Praia Cardoso Surf forecast

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