The Lowdown
Alright, let’s translate that for the tape measure crowd.
The best window is Monday the 7th into Tuesday the 15th. That Monday morning has waves around 6 to 7 feet from the South. The real standout is Tuesday the 15th afternoon – solid 5.5 foot Southern Hemisphere groundswell with a very long period of 14 seconds, and glassy conditions. The water temperature is about 73.6°F, which is a touch warmer than usual.
The rest is small and messy. There’s a late bloomer on Friday the 18th: tiny waves only about 2 feet, but with a huge 19 second period – a oddball that might work on the points. Most other days are best spent doing something else.

Information about the Praia do Aventureiro Surf forecast
The above surf forecast table for Praia do Aventureiro 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 Aventureiro can be found by selecting the local surf guide option on the grey menu. Our Praia do Aventureiro 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 do Aventureiro) 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 do Aventureiro 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.
