Alright folks, Rusty here. Gotta be straight with you – for the next couple of weeks, it’s a tough watch out there.
The Outlook
The whole 16-day window is pretty grim at Bicas. This spot is a reef break that rarely breaks, and looking ahead, it’s not going to be doing much of it. The conditions are just a mess. It’s not until the very end of the period that we see a pulse of energy, but even then, the winds are going to ruin it.
From Wednesday the 8th right through to Monday the 21st of July, it’s all "poor surf conditions". There’s a glimmer of hope on Sunday the 20th and Monday the 21st when the swell bumps up to around 5ft to 6ft from the NNW and NW, and the combined energy gets strong, hitting 370 to 405. But don’t get too excited. That size starts to push into expert-only territory, and more importantly, the wind is cranking onshore from the NNW at up to 25 mph. It’s going to be a lumpy, choppy mess – honestly, that setup looks more interesting for kite surfing than paddle surfing. The water temp is about average for the time of year at 68°.
The very last day, Thursday the 23rd of July, is the only time the swell energy really cranks up to 693, with 6ft swell from the NNW. Again, that is big for this place, expert only, and the cross-onshore wind is still fresh at 19 mph. It’s not going to be clean.
There’s no standout day. No clean windows. If you’re desperate, maybe hope for a lull in the wind, but don’t hold your breath. This is a blank run that feels pretty normal for a spot like this. Forecasts can change though.
Stay loose.

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