The Lowdown
Alright, Rusty here. Let’s have a look at what’s cooking for Praia Cardoso.
To be straight with you, the start of this 16-day run is a real struggle. There’s nothing worth paddling out for until Tuesday the 21st of July, and even then it’s marginal at best. We’re talking a solid few days of flat, wind-affected junk. Hold your horses.
The first real glimmer shows up on Wednesday the 22nd, with a pulse of 5ft swell from the S, but the combined energy is moderate (455) and the wind is cross-off, keeping things clean. It’s not a classic, but it’s a start. The water is sitting at 60°, which is a *much colder than normal* for this time of year – we’re talking about 6° below average, so you’ll need a thick suit.
The standout window, and I mean the one to circle on the calendar, is Thursday the 30th of July. The morning brings a solid 8ft S swell, with a long period of 11 seconds – real groundswell. The energy is huge (1412), and with a light offshore breeze from the W, it’ll be glassy and clean. This is a setup for experienced surfers only; it’s too big and powerful for beginners. The combination of size, period, and wind is the best on offer by a long shot.
The Sunday the 26th of July afternoon is also a strong runner-up, with 5ft S swell at 12 seconds and clean, cross-off wind. The energy is very strong (1275), and it’s rated excellent for experienced surfers. That’s a solid session, but the 30th is the big one.
Later on, Friday the 31st of July morning has a clean 4ft SSE swell with light offshore winds – a good, more manageable option for the intermediate crew. The water is still cold, but the conditions are clean.
To wrap it up: the first week is a write-off, but from the 22nd onwards, it starts to build. The 30th of July is the day for the big-wave hunters. For everyone else, the 31st is your best bet for a clean, fun size.
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. If you surf the same spot (Praia Cardoso) 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 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.
