The Lowdown
Alright, let’s get into it. This is Rusty, looking at the Asturias forecast for the next couple of weeks. Praia de Asturias is a beach and reef setup, sheltered from the swell, and it’s an inconsistent spot that sometimes draws a crowd. The water is sitting at 71°, which is a touch warmer than normal for this time of year – nothing crazy, but you’ll notice it’s a bit more pleasant than usual.
Honestly, the first week is a real struggle. We’ve got tiny, weak swell with combined energy readings mostly under 250 (weak wave energy) and the wind just won’t cooperate. Thursday the 10th is the only thing worth paddling out for, and even then it’s just “surfable but very ordinary.” Thursday morning you get glassy conditions with a 2 ft SSE swell, 12-second period – that’s a clean, small wave for a beginner, but don’t expect much push. The wind is glassy, which is a major positive for the surface, but the swell direction is wrong for this spot (it wants east), so it’s going to be weak and soft. After that, we get a long run of poor surf right through until the 17th. Friday the 11th through Sunday the 13th is all onshore wind and messy, with a pulse of 6 ft on Sunday morning but with a 12 mph onshore wind ruining it – that’s just blown-out junk. The combined energy on Sunday morning jumps to 827 (moderate energy) but the wind kills it.
The second week is where we start to see some life, but it’s still not a standout. Friday the 18th and Saturday the 19th have glassy mornings with 2 ft to 3 ft south swells and 11-12 second periods. Combined energy is still weak (around 181 to 241), but the glassy wind makes it clean. The best of the whole forecast actually lands on Friday the 25th. That afternoon you get a glassy 3 ft SSE swell with a 13-second period, and combined energy hits 497 (moderate wave energy). The wind is glassy, so the surface will be like a mirror. That’s your window – small but clean, and the longer period means better-shaped waves, though it’s a beach and reef setup so it might break a bit straight. It’s not a big swell, but for this inconsistent spot, it’s the pick of the bunch.
If you’re a beginner, the swell never really gets above 5 ft in any clean window, so it’s safe. If you’re an expert, you’re going to be bored unless you just want a longboard session on the 25th.
So, to sum it up: the first week is a write-off with a tiny window on Thursday the 10th. The second week has a few glassy mornings, but the real highlight is Friday the 25th afternoon – small, clean, and with a bit of period. Don’t hold your breath for anything big. This place is inconsistent, and this forecast shows why.

Information about the Praia de Asturias Surf forecast
The above surf forecast table for Praia de Asturias provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Praia de Asturias can be found by selecting the local surf guide option on the grey menu. Our Praia de Asturias 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 de Asturias) 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 de Asturias 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.
Praia de Asturias is 14 km (9 miles) from the city of Praia Grande. If you plan a holiday in São Paulo, look for hotels and other accommodation in Praia Grande. Praia Grande has rooms for a wide range of budgets as well as car hire and transport links.
