The Lowdown
Alright, Rusty here. Let’s talk about what’s happening at Praia da Cal. The first week is a real slow one. Nothing worth getting wet for from now until the 9th of August. The surf is flat or tiny, the energy is low, and conditions are mostly poor or just ordinary. It’s a quiet start.
Then, on Monday the 10th of August, we finally see some life. The morning has a clean 5ft swell from the south, with a light offshore breeze. The energy is moderate (339). That afternoon, the swell jumps to 8ft from the SSW, but it gets a bit lumpy with a cross-onshore wind. The real standout, though, is Tuesday the 11th of August. You’re looking at a solid 7ft swell from the south with a long 13-second period. That’s proper groundswell, and the energy is strong (1609). The wind is glassy in the morning, making it clean. This is the best session for experienced surfers.
Wednesday the 12th of August keeps it going with a glassy 5ft south swell (12 seconds) in the morning. Good energy (759) and clean conditions. The water is about 64°, which is normal for this time of year.
Into the second week, Thursday the 13th of August offers another glassy morning with a 5-6ft SSE swell and an 11-second period. Solid energy (699). It’s a good option, but that Tuesday morning is the clear winner. After that, the surf fades out again with smaller, messy waves and stronger winds through to the end of the forecast.
So, if you’ve got one day to save, make it the morning of Tuesday the 11th of August at Praia da Cal. The 7ft south swell, long period, and glassy conditions will be the pick of the bunch. The Wednesday morning on the 12th is also worth a look. The rest of the window is a waiting game.
Rusty.

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